corrected for position and instrument error. Calibrated
airspeed is equal to true airspeed in standard atmosphere at
sea level.
KIAS
Knots Indicated Airspeed is the speed shown on the
airspeed indicator. The IAS values published in this
handbook assume no instrument error.
KTAS
Knots True Airspeed is the airspeed expressed in knots
relative to undisturbed air which is KCAS corrected for
altitude and temperature.
VG
Best Glide Speed is the speed at which the greatest flight
distance is attained per unit of altitude lost with power off.
VO
Operating Maneuvering Speed is the maximum speed at
which application of full control movement will not overstress
the airplane.
VFE
Maximum Flap Extended Speed is the highest speed
permissible with wing flaps in a prescribed extended position.
VNO
Maximum Structural Cruising Speed is the speed that
should not be exceeded except in smooth air, and then only
with caution.
VNE

General
VSO
Stalling Speed is the minimum steady flight speed at which
the aircraft is controllable in the landing configuration (100%
flaps) at the most unfavorable weight and balance.
VX
Best Angle of Climb Speed is the speed at which the
airplane will obtain the highest altitude in a given horizontal
distance. The best angle-of-climb speed normally increases
slightly with altitude.
VY
Best Rate of Climb Speed is the speed at which the
airplane will obtain the maximum increase in altitude per unit
of time. The best rate-of-climb speed decreases slightly with
altitude.
Meteorological Terminology
IMC
Instrument Meteorological Conditions are meteorological
conditions expressed in terms of visibility, distance from
cloud, and ceiling less than the minima for visual flight
defined in FAR 91.155.
ISA
International Standard Atmosphere (standard day) is an
atmosphere where (1) the air is a dry perfect gas, (2) the
temperature at sea level is 15° C, (3) the pressure at sea
level is 29.92 in.Hg (1013.2 millibars), and (4) the
temperature gradient from sea level to the altitude at which
the temperature is -56.5° C is -0.00198° C per foot and zero
above that altitude.
MSL
Mean Sea Level is the average height of the surface of the
sea for all stages of tide. In this Handbook, altitude given as
MSL is the altitude above the mean sea level. It is the
altitude read from the altimeter when the altimeter’s
barometric adjustment has been set to the altimeter setting
obtained from ground meteorological sources.
OAT
Outside Air Temperature is the free air static temperature
obtained from inflight temperature indications or from ground
meteorological sources. It is expressed in either degrees
Celsius or degrees Fahrenheit.

•
Pressure Altitude is the altitude read from the altimeter
when the altimeter’s barometric adjustment has been set to
29.92 in.Hg (1013 mb) corrected for position and instrument
error. In this Handbook, altimeter instrument errors are
assumed to be zero.
•
Standard Temperature is the temperature that would be
found at a given pressure altitude in the standard
atmosphere. It is 15° C (59° F) at sea level pressure altitude
and decreases approximately 2° C (3.6° F) for each 1000
feet of altitude increase. See ISA definition.
Engine Power Terminology
HP
Horsepower is the power developed by the engine.
MCP
Maximum Continuous Power is the maximum power that
can be used continuously.
MAP
Manifold Pressure is the pressure measured in the
engine’s induction system expressed as in. Hg.
RPM
Revolutions Per Minute is engine rotational speed.
•
Static RPM is RPM attained during a full-throttle engine
runup when the airplane is on the ground and stationary.
Performance and Flight Planning Terminology
g
One “g” is a quantity of acceleration equal to that of earth’s
gravity.
•
Demonstrated Crosswind Velocity is the velocity of the
crosswind component for which adequate control of the
airplane during taxi, takeoff, and landing was actually
demonstrated during certification testing. Demonstrated
crosswind is not considered to be limiting.
•
Service Ceiling is the maximum altitude at which the
aircraft at maximum weight has the capability of climbing at
a rate of 100 feet per minute.
GPH

NMPG
Nautical Miles Per Gallon is the distance (in nautical miles)
which can be expected per gallon of fuel consumed at a
specific engine power setting and/or flight configuration.
•
Unusable Fuel is the quantity of fuel that cannot be safely
used in flight.
•
Usable Fuel is the fuel available for flight planning.
Weight and Balance Terminology
c.g.
Center of Gravity is the point at which an airplane would
balance if suspended. Its distance from the reference datum
is found by dividing the total moment by the total weight of
the airplane.
•
Arm is the horizontal distance from the reference datum to
the center of gravity (c.g.) of an item. The airplane’s arm is
obtained by adding the airplane’s individual moments and
dividing the sum by the total weight.
•
Basic Empty Weight is the actual weight of the airplane
including all operating equipment that has a fixed location in
the airplane. The basic empty weight includes the weight of
unusable fuel and full oil.
MAC
Mean Aerodynamic Chord is the chord drawn through the
centroid of the wing plan area.
LEMAC
Leading Edge of Mean Aerodynamic Chord is the forward
edge of MAC given in inches aft of the reference datum
(fuselage station).
•
Maximum Gross Weight is the maximum permissible
weight of the airplane and its contents as listed in the aircraft
specifications.
•
Moment is the product of the weight of an item multiplied by
its arm.
•
Useful Load is the basic empty weight subtracted from the
maximum weight of the aircraft. It is the maximum allowable
combined weight of pilot, passengers, fuel and baggage.

•
Station is a location along the airplane fuselage measured
in inches from the reference datum and expressed as a
number. For example: A point 123 inches aft of the reference
datum is Fuselage Station 123.0 (FS 123).
•
Reference Datum is an imaginary vertical plane from which
all horizontal distances are measured for balance purposes.
•
Tare is the weight of all items used to hold or position the
airplane on the scales for weighing. Tare includes blocks,
shims, and chocks. Tare weight must be subtracted from the
associated scale reading.

Emergency Procedures Guidance
Although this section provides procedures for handling most
emergencies and critical flight situations that could arise in the SR22,
it is not a substitute for thorough knowledge of the airplane and
general aviation techniques. A thorough study of the information in this
handbook while on the ground will help you prepare for time-critical
situations in the air.
Preflight Planning
Enroute emergencies caused by weather can be minimized or
eliminated by careful flight planning and good judgment when
unexpected weather is encountered.
Preflight Inspections/Maintenance
In-flight mechanical problems in the SR22 will be extremely rare if
proper preflight inspections and maintenance are practiced. Always
perform a thorough walk-around preflight inspection before any flight
to ensure that no damage occurred during the previous flight or while
the airplane was on the ground. Pay special attention to any oil leaks
or fuel stains that could indicate engine problems.
Methodology
Aircraft emergencies are very dynamic events. Because of this, it is
impossible to address every action a pilot might take to handle a
situation. However, four basic actions can be applied to any
emergency. They are:
Maintain Aircraft Control — Many minor aircraft emergencies turn
into major ones when the pilot fails to maintain aircraft control.
Remember, do not panic and do not fixate on a particular problem.
Over-attention to a faulty warning light during an instrument approach
can lead to a pilot induced unusual attitude and possibly worse. To
avoid this, even in an emergency: aviate, navigate, and communicate,
in this order. Never let anything interfere with your control of the
airplane. Never stop flying.
Analyze the Situation — Once you are able to maintain control of the
aircraft, assess the situation. Look at the engine parameters. Listen to
the engine. Determine what the airplane is telling you.

Emergency Procedures
Cirrus Design
SR22
Take Appropriate Action — In most situations, the procedures listed
in this section will either correct the aircraft problem or allow safe
recovery of the aircraft. Follow them and use good pilot judgment.
The Cirrus Airframe Parachute System (CAPS) should be activated in
the event of a life-threatening emergency where CAPS deployment is
determined to be safer than continued flight and landing. Refer to
Section 10, Safety Information, for CAPS deployment information and
landing considerations.
Land as soon as Conditions Permit — Once you have handled the
emergency, assess your next move. Handle any non-critical “clean-up”
items in the checklist and put the aircraft on the ground. Remember,
even if the airplane appears to be in sound condition, it may not be.

Section 3
Emergency Procedures
Engine Partial Power Loss
Indications of a partial power loss include fluctuating RPM, reduced or
fluctuating manifold pressure, low oil pressure, high oil temperature,
and a rough-sounding or rough-running engine. Mild engine
roughness in flight may be caused by one or more spark plugs
becoming fouled. A sudden engine roughness or misfiring is usually
evidence of a magneto malfunction.
• Note •
Low oil pressure may be indicative of an imminent engine
failure – Refer to Low Oil Pressure procedure in this section
for special procedures with low oil pressure.
• Note •
A damaged (out-of-balance) propeller may cause extremely
rough operation. If an out-of-balance propeller is suspected,
immediately shut down engine and perform Forced Landing
checklist.
If a partial engine failure permits level flight, land at a suitable airfield
as soon as conditions permit. If conditions do not permit safe level
flight, use partial power as necessary to set up a forced landing
pattern over a suitable landing field. Always be prepared for a
complete engine failure and consider CAPS deployment if a suitable
landing site is not available. Refer to Section 10, Safety Information,
for CAPS deployment scenarios and landing considerations.
If the power loss is due to a fuel leak in the injector system, fuel
sprayed over the engine may be cooled by the slipstream airflow which
may prevent a fire at altitude. However, as the Power Lever is reduced
during descent and approach to landing the cooling air may not be
sufficient to prevent an engine fire.
• WARNING •
If there is a strong smell of fuel in the cockpit, divert to the
nearest suitable landing field. Fly a forced landing pattern and
shut down the engine fuel supply once a safe landing is
assured.

The following procedure provides guidance to isolate and correct
some of the conditions contributing to a rough running engine or a
partial power loss:
1. Air Conditioner (if installed) ......................................................OFF
2. Fuel Pump.......................................................................... BOOST
Selecting BOOST on may clear the problem if vapor in the
injection lines is the problem or if the engine-driven fuel pump has
partially failed. The electric fuel pump will not provide sufficient
fuel pressure to supply the engine if the engine-driven fuel pump
completely fails.
3. Fuel Selector ........................................................ SWITCH TANKS
Selecting the opposite fuel tank may resolve the problem if fuel
starvation or contamination in one tank was the problem.
4. Mixture ............................. CHECK appropriate for flight conditions
5. Power Lever ....................................................................... SWEEP
Sweep the Power Lever through range as required to obtain
smooth operation and required power.
6. Alternate Induction Air............................................................... ON
A gradual loss of manifold pressure and eventual engine
roughness may result from the formation of intake ice. Opening
the alternate engine air will provide air for engine operation if the
normal source is blocked or the air filter is iced over.
7. Ignition Switch ...................................................... BOTH, L, then R
Cycling the ignition switch momentarily from BOTH to L and then
to R may help identify the problem. An obvious power loss in
single ignition operation indicates magneto or spark plug trouble.
Lean the mixture to the recommended cruise setting. If engine
does not smooth out in several minutes, try a richer mixture
setting. Return ignition switch to the BOTH position unless
extreme roughness dictates the use of a single magneto.
8. Land as soon as practical.

Emergency Procedures
Low Oil Pressure
If low oil pressure is accompanied by a rise in oil temperature, the
engine has probably lost a significant amount of its oil and engine
failure may be imminent. Immediately reduce engine power to idle and
select a suitable forced landing field.
• WARNING •
Prolonged use of high power settings after loss of oil pressure
will lead to engine mechanical damage and total engine
failure, which could be catastrophic.
• Note •
Full power should only be used following a loss of oil pressure
when operating close to the ground and only for the time
necessary to climb to an altitude permitting a safe landing or
analysis of the low oil pressure indication to confirm oil
pressure has actually been lost.
If low oil pressure is accompanied by normal oil temperature, it
is possible that the oil pressure sensor, gage, or relief valve is
malfunctioning. In any case, land as soon as practical and
determine cause.
1. Power Lever ................................................ MINIMUM REQUIRED
2. Land as soon as possible.
Propeller Governor Failure
If the RPM does not respond to power lever movement or overspeeds,
the most likely cause is a faulty governor or an oil system malfunction.
If moving the power lever is difficult or rough, suspect a power lever
linkage failure and perform the Power Lever Linkage Failure checklist.
Propeller RPM will not increase:
1. Oil Pressure ....................................................................... CHECK
2. Land as soon as practical.
Propeller overspeeds or will not decrease:
1. Power Lever ................................. ADJUST (to keep RPM in limits)

Spins
The SR22 is not approved for spins, and has not been tested or
certified for spin recovery characteristics. The only approved and
demonstrated method of spin recovery is activation of the Cirrus
Airframe Parachute System (See CAPS Deployment, this section).
Because of this, if the aircraft “departs controlled flight,” the CAPS
must be deployed.
While the stall characteristics of the SR22 make accidental entry into a
spin extremely unlikely, it is possible. Spin entry can be avoided by
using good airmanship: coordinated use of controls in turns, proper
airspeed control following the recommendations of this Handbook, and
never abusing the flight controls with accelerated inputs when close to
the stall (see Stalls, Section 4).
If, at the stall, the controls are misapplied and abused accelerated
inputs are made to the elevator, rudder and/or ailerons, an abrupt wing
drop may be felt and a spiral or spin may be entered. In some cases it
may be difficult to determine if the aircraft has entered a spiral or the
beginning of a spin.
• WARNING •
In all cases, if the aircraft enters an unusual attitude from
which recovery is not expected before ground impact,
immediate deployment of the CAPS is required.
The minimum demonstrated altitude loss for a CAPS
deployment from a one-turn spin is 920 feet. Activation at
higher altitudes provides enhanced safety margins for
parachute recoveries. Do not waste time and altitude trying to
recover from a spiral/spin before activating CAPS.

CAPS Deployment
The Cirrus Airframe Parachute System (CAPS) should be activated in
the event of a life-threatening emergency where CAPS deployment is
determined to be safer than continued flight and landing.
• WARNING •
CAPS deployment is expected to result in loss of the airframe
and, depending upon adverse external factors such as high
deployment speed, low altitude, rough terrain or high wind
conditions, may result in severe injury or death to the
occupants. Because of this, CAPS should only be activated
when any other means of handling the emergency would not
protect the occupants from serious injury.
• Caution •
Expected impact in a fully stabilized deployment is equivalent
to a drop from approximately 13 feet.
• Note •
Several possible scenarios in which the activation of the
CAPS would be appropriate are discussed in Section 10 Safety Information, of this Handbook. These include:
• Mid-air collision
• Structural failure
• Loss of control
• Landing in inhospitable terrain
• Pilot incapacitation
All pilots should carefully review the information on CAPS
activation and deployment in Section 10 before operating the
airplane.
Once the decision is made to deploy CAPS, the following actions
should be taken:

Generally, a distressed airplane will be safer for its occupants if
the engine is not running.
3. Activation Handle Cover.................................................. REMOVE
The cover has a handle located at the forward edge. Pull cover
down to expose activation T-handle.
4. Activation Handle (Both Hands) ............. PULL STRAIGHT DOWN
Pull the activation T-handle from its holder. Clasp both hands
around the handle and pull straight down in a strong, steady, and
continuous motion. Maintain maximum pull force until the rocket
activates. Pull forces up to, or exceeding, 45 pounds may be
required. Bending of the handle-housing mount is to be expected.
• WARNING •
Jerking or rapidly pulling the activation T-handle will greatly
increase the pull forces required to activate the rocket. Use a
firm and steady pulling motion – a “chin-up” type pull
enhances successful activation.
After Deployment:

conditions or terrain does not permit a safe landing, CAPS deployment
may be required. Refer to Section 10, Safety Information, for CAPS
deployment scenarios and landing considerations.
A suitable field should be chosen as early as possible so that
maximum time will be available to plan and execute the forced landing.
For forced landings on unprepared surfaces, use full flaps if possible.
Land on the main gear and hold the nose wheel off the ground as long
as possible. If engine power is available, before attempting an “off
airport” landing, fly over the landing area at a low but safe altitude to
inspect the terrain for obstructions and surface conditions.

Primary Flight Display System
In the unlikely event of a PFD failure, the pilot may lose the ability to
control the autopilot through the PFD controls. If this malfunction
occurs, the PFD circuit breakers may be pulled and the airplane flown
using the mechanical standby instruments. With the PFD circuit
breakers pulled, autopilot lateral control is available in GPSS steering
mode through GPS 1 and autopilot vertical control is available through
the Vertical Speed (VS) and Altitude (ALT) modes on the autopilot
head. Dim brightness level to black if PFD is found distracting.
PFD - Loss of Air Data
In the event the PFD detects a loss of air data, the affected indicator is
removed from the display and replaced with a red “X”. If loss of air data

message. In the event of a power loss greater than 20
seconds, a warm start is unlikely, and the power interruption
will result in loss of attitude information until the PFD can be
restarted on the ground.
Power Lever Linkage Failure
If the Power Lever linkage fails in flight, the engine will not respond to
power lever control movements. Use power available and flaps as
required to safely land the airplane.
If the power lever is stuck at or near the full power position, proceed to
a suitable airfield. Fly a forced landing pattern. With landing assured,
shut down engine by moving mixture control full aft to CUTOFF. If
power is needed again, return mixture control to full RICH and regain
safe pattern parameters or go-around. If airspeed cannot be
controlled, shut engine down and perform the Forced Landing
checklist. After landing, bring the airplane to a stop and complete the
Emergency Engine Shutdown on Ground checklist.
If the power lever is stuck at or near the idle position and straight and
level flight cannot be maintained, establish glide to a suitable landing
surface. Fly a forced landing pattern.
1. Power Lever Movement...................................................... VERIFY
2. Power .............................................................................SET if able

Abnormal Procedures Guidance
Although this section provides procedures for handling most abnormal
system and/or flight conditions that could arise in the SR22, it is not a
substitute for thorough knowledge of the airplane and general aviation
techniques. A thorough study of the information in this handbook while
on the ground will help you prepare for time-critical situations in the air.
Sound judgement as well as thorough knowledge of the aircraft, its
characteristics, and the flight manual procedures are essential in the
handling of any abnormal system and/or flight condition. In addition to
the outlined items in the Abnormal Procedures, the following steps are
considered part of all abnormal situations:
• Maintain Aircraft Control
• Analyze the Situation
• Take Appropriate Action

Ground Procedures
Brake Failure During Taxi
Ground steering is accomplished by differential braking. However,
increasing power may allow some rudder control due to increased
groundspeed and airflow over the rudder.
1. Engine Power......................................................... AS REQUIRED
• To stop airplane - REDUCE
• If necessary for steering - INCREASE
2. Directional Control ............................... MAINTAIN WITH RUDDER
3. Brake Pedal(s) ......................................................................PUMP
If directional control can not be maintained:
4. Mixture ..............................................................................CUTOFF
Aborted Takeoff
Use as much of the remaining runway as needed to safely bring the
airplane to a stop or to slow the airplane sufficiently to turn off the
runway.
1. Power Lever ............................................................................ IDLE
2. Brakes.................................................................... AS REQUIRED
• Caution •
For maximum brake effectiveness, retract flaps, hold control
yoke full back, and bring the airplane to a stop by smooth,
even application of the brakes to avoid loss of control and/or a
blown tire.
After a high-speed aborted takeoff, brake temperatures will be
elevated; subsequent aborted takeoffs or other high-energy
use of the brakes may cause brake overheat, failure and
possibly even fire. A 25-minute cooling time is recommended
following high-energy use of the brake system before
attempting to conduct operations that may require further
high-energy braking. Brake temperature indicator should be
inspected prior to flight following a high-energy brake event
(refer to Preflight Walk-Around Checklist for detail).

In-Flight Procedures
Inadvertent Icing Encounter
Flight into known icing conditions is prohibited. However, If icing is
inadvertently encountered:
1. Pitot Heat .................................................................................. ON
2. Exit icing conditions. Turn back or change altitude.
3. Cabin Heat .................................................................... MAXIMUM
4. Windshield Defrost ...................................................... FULL OPEN
5. Alternate Induction Air............................................................... ON
Inadvertent IMC Encounter
Upon entering IMC, a pilot who is not completely proficient in
instrument flying should rely upon the autopilot to execute a 180° turn
to exit the conditions. Immediate action should be made to turn back
as follows:
1. Airplane Control ........................Establish Straight and Level Flight
2. Autopilot ............................... Engage to hold Heading and Altitude
3. Heading.................................................. Reset to initiate 180° turn
Door Open In Flight
The doors on the airplane will remain 1-3 inches open in flight if not
latched. If this is discovered on takeoff roll, abort takeoff if practical. If
already airborne do not allow efforts to close the door interfere with the
primary task of maintaining control of the airplane. Do not attempt to
hold door closed. Upon landing flare door may swing open - do not
attempt to close door.
1. Airplane Control ............................................................. MAINTAIN

System Malfunctions
Alternator Failure
Steady illumination of either ALT caution light in the annunciator panel
indicates a failure of the corresponding alternator. The most likely the
cause of the alternator failure is a wiring fault, a malfunctioning
alternator, or a malfunctioning control unit. Usually, electrical power
malfunctions are accompanied by an excessive rate of charge or a
discharge rate shown on the ammeter.
• Caution •
Alternators in this airplane are self-exciting. These alternators
require battery power for alternator starting; however, once
started, the alternators will provide self-generated field power
to continue operation in case of a battery failure. To assure
alternator restart power is available if the alternators fail, the
batteries should not be turned off during flight.
Serials 0002 thru 1643 and 1645 thru 1666: A flashing ALT 1 light
indicates an excessive charging rate. This could occur with a very low
BAT 1 and heavy equipment loads. Since the loads on ALT 2 are much
lower, it is unlikely that a flashing ALT 2 light could occur, even with a
very low BAT 2.
The Power Distribution Schematic shows the electrical system power
distribution. Individual loads on each circuit breaker panel bus are
shown in the same order as they are on the panel. Note that items on
the circuit breaker panel Essential buses are powered from ALT 1, ALT
2, BAT 1, and BAT 2. The circuit breaker panel Main buses and NonEssential buses are powered from ALT 1 and BAT 1 only.
• Note •
If it is necessary to reduce electrical loads due to an alternator
malfunction, switch off electrical components and/or systems
that are not essential for the current flight conditions rather
than pulling circuit breakers. Load shedding in this manner will
prevent accidental circuit breaker disconnection and loss of
power to flight-critical systems. See Figure Electrical Power
Distribution, for details on electrical busses and what
components/systems they power.

ALT 1 Light Steady
Steady illumination indicates a failure of ALT 1. Attempt to bring
alternator back on line. If alternator cannot be brought back, reduce
loads and use Main Bus or Non-Essential loads only as necessary for
flight conditions.
1. ALT 1 Master Switch ................................................................OFF
2. Alternator 1 Circuit Breaker............................ CHECK and RESET
3. ALT 1 Master Switch ................................................................. ON
If alternator does not reset:
4. Switch off unnecessary equipment on Main Bus 1, Main Bus 2,
and the Non-Essential Buses to reduce loads. Monitor voltage.
5. ALT 1 Master Switch ................................................................OFF
6. Land as soon as practical.
ALT 1 Light Flashing
Serials 0002 thru 1643 and 1645 thru 1666: The most likely cause is a
severely discharged battery along with heavy equipment loads. In this
event, reduce loads on Main and Non-Essential buses and monitor
amperage until charging rate is within normal limits. Then loads can be
added as required.
1. Ammeter Switch ..................................................................... BATT
2. If charging rate is greater than 30 amps, reduce load on Main Bus
1, Main Bus 2, and Non-Essential buses.
3. Monitor ammeter until battery charge rate is less than 15 amps.
4. When battery charge rate is within limits, add loads as necessary
for flight conditions.
ALT 2 Light Steady
Except during low RPM operations, steady illumination indicates a
failure of ALT 2. If alternator cannot be brought back, Essential bus
loads will be powered from ALT 1, BAT 1, and BAT 2.
• Note •
ALT 2 light will illuminate steady and ALT 2 will not come on
line until 1700 - 2200 RPM.
1. ALT 2 Master Switch ................................................................OFF

Engine Indicating System Failure
Serials 1644, 1663 and Subsequent: In the event of an Data
Acquisition Unit (DAU) failure, the engine indications displayed on the
MFD and PFD will be disabled. Numeric readouts will display as three
white dashes, the CHT and EGT bar graphs will be removed, and
indicator needles displayed on the simulated gages will be removed.
In the event of DAU failure, pull and reset the ANNUN / ENGINE INST
circuit breaker. If the engine indicating system fails to reset, land as
soon as practical.
1. ANNUN / ENGINE INST Circuit Breaker ............................... Cycle
2. Land as soon as practical.
LOW VOLTS Warning Light Illuminated
Illumination of the LOW VOLTS light indicates that the voltage
measured at the Essential Bus is 24.5 volts or less. Typically, this
indicates that the airplane is operating on battery power only and both
alternators have failed or are off. If both alternators have failed:
1. Land as soon as practical.

Abnormal Procedures
Pitot Static Malfunction
Static Source Blocked
If erroneous readings of the static source instruments (airspeed,
altimeter and vertical speed) are suspected, the alternate static source
valve, on side of console near pilot’s right ankle, should be opened to
supply static pressure from the cabin to these instruments.
• Note •
If selecting the alternate static source does not work, in an
emergency, cabin pressure can be supplied to the static
pressure instruments by breaking the glass in the face of the
vertical speed indicator. When static pressure is supplied
through the vertical speed indicator, the vertical speed UPDOWN indications will be reversed (i.e., the needle will
indicate UP for descent and DOWN for climb).
With the alternate static source on, adjust indicated airspeed slightly
during climb or approach according to the Airspeed Calibration
(Alternate Static Source) table in Section 5 as appropriate for vent/
heater configuration.
1. Pitot Heat ...................................................................................ON
2. Alternate Static Source ......................................................... OPEN
Pitot Tube Blocked
If only the airspeed indicator is providing erroneous information, and in
icing conditions, the most probable cause is pitot ice. If setting Pitot
Heat ON does not correct the problem, descend to warmer air. If an
approach must be made with a blocked Pitot tube, use known pitch
and power settings and the GPS groundspeed indicator, taking
surface winds into account.

Before carrying out preflight inspections, ensure that all required
maintenance has been accomplished. Review your flight plan and
compute weight and balance.
• Note •
Throughout the walk-around: check all hinges, hinge pins, and
bolts for security; check skin for damage, condition, and
evidence of delamination; check all control surfaces for proper
movement and excessive free play; check area around liquid
reservoirs and lines for evidence of leaking.
In cold weather, remove all frost, ice, or snow from fuselage,
wing, stabilizers and control surfaces. Ensure that control
surfaces are free of internal ice or debris. Check that wheel
fairings are free of snow and ice accumulation. Check that
pitot probe warms within 30 seconds of setting Pitot Heat to

Normal Procedures
Starting Engine
If the engine is warm, no priming is required. For the first start of the
day and in cold conditions, prime will be necessary.
Weak intermittent firing followed by puffs of black smoke from the
exhaust stack indicates over-priming or flooding. Excess fuel can be
cleared from the combustion chambers by the following procedure:
• Turn fuel pump off.
• Allow fuel to drain from intake tubes.
• Set the mixture control full lean and the power lever full open.
• Crank the engine through several revolutions with the starter.
• When engine starts, release ignition switch, retard power lever,
and slowly advance the mixture control to FULL RICH position.
If the engine is under-primed, especially with a cold soaked engine, it
will not fire, and additional priming will be necessary. As soon as the
cylinders begin to fire, open the power lever slightly to keep it running.
Refer to Cold Weather Operation in this section or additional
information regarding cold weather operations.
• WARNING •
If airplane will be started using external power, keep all
personnel and power unit cables well clear of the propeller
rotation plane.
• Caution •
Alternators should be left OFF during engine starting to avoid
high electrical loads.
After starting, if the oil gage does not begin to show pressure
within 30 seconds in warm weather and about 60 seconds in
very cold weather, shut down engine and investigate cause.
Lack of oil pressure indicates loss of lubrication, which can
cause severe engine damage.

Taxiing
When taxiing, directional control is accomplished with rudder

as much power as is necessary to achieve forward movement.
Deceleration or taxi speed control using brakes but without a reduction
in power will result in increased brake temperature. Taxi over loose
gravel at low engine speed to avoid damage to the propeller tips.
• WARNING •
Maximum continuous engine speed for taxiing is 1000 RPM
on flat, smooth, hard surfaces. Power settings slightly above
1000 RPM are permissible to start motion, for turf, soft
surfaces, and on inclines. Use minimum power to maintain taxi
speed.
If the 1000 RPM taxi power limit and proper braking
procedures are not observed, the brake system may overheat
and result in brake damage or brake fire.

Normal Procedures
Takeoff
Power Check: Check full-throttle engine operation early in takeoff run.
The engine should run smoothly and turn approximately 2700 RPM.
All engine parameters should read in the green. Discontinue takeoff at
any sign of rough operation or sluggish acceleration. Make a thorough
full-throttle static run-up before attempting another takeoff.
For takeoff over a gravel surface, advance Power Lever slowly. This
allows the airplane to start rolling before high RPM is developed, and
gravel will be blown behind the propeller rather than pulled into it.
Flap Settings: Normal and short field takeoffs are accomplished with
flaps set at 50%. Takeoffs using 0% are permissible, however, no
performance data is available for takeoffs in the flaps up configuration.
Takeoffs with 100% flaps are not approved.
Soft or rough field takeoffs are performed with 50% flaps by lifting the
airplane off the ground as soon as practical in a tail-low attitude. If no
obstacles are ahead, the airplane should be leveled off immediately to
accelerate to a higher climb speed.
Takeoffs into strong crosswinds are normally performed with the flaps
set at 50% to minimize the drift angle immediately after takeoff. With
the ailerons fully deflected into the wind, accelerate the airplane to a
speed slightly higher than normal while decreasing the aileron
deflection as speed increases then - with authority - rotate to prevent
possibly settling back to the runway while drifting. When clear of the
ground, make a coordinated turn into the wind to correct for drift.
• Note •
Fuel BOOST should be left ON during takeoff and for climb as
required for vapor suppression with hot or warm fuel.

speeds give the best combination of performance, visibility and engine
cooling.
For maximum rate of climb, use the best rate-of-climb speeds shown
in the rate-of-climb chart in Section 5. If an obstruction dictates the use
of a steep climb angle, the best angle-of-climb speed should be used.
Climbs at speeds lower than the best rate-of-climb speed should be of

Cruise
Normal cruising is performed between 55% and 85% power. The
engine power setting and corresponding fuel consumption for various
altitudes and temperatures can be determined by using the cruise data
in Section 5.
The selection of cruise altitude is made based on the most favorable
wind conditions and the desired power settings. These significant
factors should be considered on every trip to reduce fuel consumption.
• Note •
For engine break-in, cruise at a minimum of 75% power until
the engine has been operated for at least 25 hours or until oil
consumption has stabilized. Operation at this higher power will
ensure proper seating of the rings, is applicable to new
engines, and engines in service following cylinder

Cruise Leaning
Exhaust gas temperature (EGT) may be used as an aid for mixture
leaning in cruise flight. For “Best Power” use 75% power or less.
For “Best Economy” use 65% power or less. To adjust the mixture,
lean to establish the peak EGT as a reference point and then adjust
the mixture by the desired increment based on the following table:

Landing
• Caution •
Landings should be made with full flaps. Landings with less
than full flaps are recommended only if the flaps fail to deploy
or to extend the aircraft’s glide distance due to engine
malfunction. Landings with flaps at 50% or 0%; power should
be used to achieve a normal glidepath and low descent rate.
Flare should be minimized.
Before landing, verify aircraft Center of Gravity does not fall in
the landing limitation zone as depicted in the C.G. Envelope in
section 2. Allow flight time for fuel burn so the landing C.G.
falls outside of this zone.
Normal Landing
Normal landings are made with full flaps with power on or off. Surface
winds and air turbulence are usually the primary factors in determining
the most comfortable approach speeds.
Actual touchdown should be made with power off and on the main
wheels first to reduce the landing speed and subsequent need for
braking. Gently lower the nose wheel to the runway after airplane
speed has diminished. This is especially important for rough or soft
field landings.
Short Field Landing
For a short field landing in smooth air conditions, make an approach at
77 KIAS with full flaps using enough power to control the glide path
(slightly higher approach speeds should be used under turbulent air
conditions). After all approach obstacles are cleared, progressively
reduce power to reach idle just before touchdown and maintain the
approach speed by lowering the nose of the airplane. Touchdown
should be made power-off and on the main wheels first. Immediately
after touchdown, lower the nose wheel and apply braking as required.
For maximum brake effectiveness, retract the flaps, hold the control
yoke full back, and apply maximum brake pressure without skidding.
Crosswind Landing
Normal crosswind landings are made with full flaps. Avoid prolonged
slips. After touchdown, hold a straight course with rudder and brakes

as required. The maximum allowable crosswind velocity is dependent
upon pilot capability as well as aircraft limitations. Operation in direct
crosswinds of 20 knots has been demonstrated.
Balked Landing/Go-Around
In a balked landing (go around) climb, disengage autopilot, apply full
power, then reduce the flap setting to 50%. If obstacles must be
cleared during the go around, climb at 75-80 KIAS with 50% flaps.
After clearing any obstacles, retract the flaps and accelerate to the

Stalls
SR22 stall characteristics are conventional. Power-off stalls may be
accompanied by a slight nose bobbing if full aft stick is held. Power-on
stalls are marked by a high sink rate at full aft stick. Power-off stall
speeds at maximum weight for both forward and aft C.G. positions are
presented in Section 5 - Performance Data.
When practicing stalls at altitude, as the airspeed is slowly reduced,
you will notice a slight airframe buffet and hear the stall speed warning
horn sound between 5 and 10 knots before the stall. Normally, the stall
is marked by a gentle nose drop and the wings can easily be held level
or in the bank with coordinated use of the ailerons and rudder. Upon
stall warning in flight, recovery is accomplished by immediately by
reducing back pressure to maintain safe airspeed, adding power if
necessary and rolling wings level with coordinated use of the controls.
• WARNING •
Extreme care must be taken to avoid uncoordinated,
accelerated or abused control inputs when close to the stall,
especially when close to the ground.

Environmental Considerations
Cold Weather Operation
Starting
If the engine has been cold soaked, it is recommended that the
propeller be pulled through by hand several times to break loose or
limber the oil. This procedure will reduce power draw on the battery if a
battery start is made.
When the engine has been exposed to temperatures at or below 20°
Fahrenheit (-7° C) for a period of two hours or more, the use of an
external pre-heater and external power is recommended. Failure to
properly preheat a cold-soaked engine may result in oil congealing
within the engine, oil hoses, and oil cooler with subsequent loss of oil
flow, possible internal damage to the engine, and subsequent engine
failure.
If the engine does not start during the first few attempts, or if engine
firing diminishes in strength, the spark plugs have probably frosted
over. Preheat must be used before another start is attempted.
• WARNING •
If airplane will be started using external power, keep all
personnel and power unit cables well clear of the propeller
rotation plane.
• Caution •
Inadequate application of preheat to a cold soaked engine
may warm the engine enough to permit starting but will not decongeal oil in the sump, lines, cooler, filter, etc. Congealed oil
in these areas will require considerable preheat.
An engine that has been superficially warmed, may start and
appear to run satisfactorily, but can be damaged from lack of
lubrication due to the congealed oil blocking proper oil flow
through the engine. The amount of damage will vary and may
not become evident for many hours. However, the engine may
be severely damaged and may fail shortly following application
of high power. Proper procedures require thorough application
of preheat to all parts of the engine. Hot air must be applied
directly to the oil sump and external oil lines as well as the

be ON for engine start and takeoff, and should be ON during climb for
vapor suppression which could occur under hot ambient conditions or
after extended idle.
Ground Operation of Air Conditioning System (Optional)
• Note •
To facilitate faster cabin cooling, prior to engine start leave the
cabin doors open for a short time to allow hot air to escape
cabin.

No determination has been made by the Federal Aviation
Administration that the noise levels of this airplane are or should be
acceptable or unacceptable for operation at, into, or out of, any airport.
The above noise levels were established at 3400 pounds takeoff
weight and 2700 RPM.
Recently, increased emphasis on improving environmental quality
requires all pilots to minimize the effect of airplane noise on the public.
The following suggested procedures minimize environmental noise
when operating the SR22.
• Note •
Do not follow these noise abatement procedures where they
conflict with Air Traffic Control clearances or instructions,
weather considerations, or wherever they would reduce safety.
1. When operating VFR over noise-sensitive areas, such as outdoor
events, parks, and recreational areas, fly not less than 2000 feet
above the surface even though flight at a lower level may be
allowed.
2. For departure from or approach to an airport, avoid prolonged
flight at low altitude near noise-sensitive areas.

Section 5
Performance Data
Introduction
Performance data in this section are presented for operational
planning so that you will know what performance to expect from the
airplane under various ambient and field conditions. Performance data
are presented for takeoff, climb, and cruise (including range &
endurance).
Associated Conditions Affecting Performance
Computed performance data in this section are based upon data
derived from actual flight testing with the airplane and engine in good
condition and using average piloting techniques. Unless specifically
noted in the “Conditions” notes presented with each table, ambient
conditions are for a standard day (refer to Section 1). Flap position as
well as power setting technique is similarly noted with each table.
The charts in this section provide data for ambient temperatures from
–20° C (–4° F) to 40° C (104° F). If ambient temperature is below the
chart value, use the lowest temperature shown to compute
performance. This will result in more conservative performance
calculations. If ambient temperature is above the chart value, use
extreme caution as performance degrades rapidly at higher
temperatures.
All fuel flow data for cruise is based on the recommended lean mixture
setting detailed in Section 4 – Normal Procedures.
Aircraft with optional Air Conditioning System; Brake Horsepower is
reduced by approximately 6 BHP.
Demonstrated Operating Temperature
Satisfactory engine cooling has been demonstrated for this airplane
with an outside air temperature 23° C above standard. The value given
is not considered an operating limitation. Reference should be made
to Section 2 for engine operating limitations.

• Runway.........................................................................................Dry, Level, Paved
• Flaps................................................................................................................. 50%
• Air Conditioner.................................................................................................. OFF
• Power:
• Throttle ................................................................................................Full Open
• Mixture ...................................................................................... Set per Placard
Set prior to brake release for short field takeoff.
The following factors are to be applied to the computed takeoff distance for
the noted condition:
• Headwind - Subtract 10% from computed distance for each 12 knots headwind.
• Tailwind - Add 10% for each 2 knots tailwind up to 10 knots.
• Grass Runway, Dry - Add 20% to ground roll distance.
• Grass Runway, Wet - Add 30% to ground roll distance.
• Sloped Runway - Increase table distances by 22% of the ground roll distance at
Sea Level, 30% of the ground roll distance at 5000 ft, 43% of the ground roll
distance at 10,000 ft for each 1% of upslope. Decrease table distances by 7% of
the ground roll distance at Sea Level, 10% of the ground roll distance at 5000 ft,
and 14% of the ground roll distance at 10,000 ft for each 1% of downslope.
• Caution •
The above corrections for runway slope are required to be included herein.
These corrections should be used with caution since published runway slope
data is usually the net slope from one end of the runway to the other. Many
runways will have portions of their length at greater or lesser slopes than the
published slope, lengthening (or shortening) takeoff ground roll estimated
from the table.
• If brakes are not held while applying power, distances apply from point where full
throttle and mixture setting is complete.
• For operation in outside air temperatures colder than this table provides, use
coldest data shown.
• For operation in outside air temperatures warmer than this table provides, use
extreme caution.

to 50 FT obstacle, then reduce power passing the estimated 50 foot point and
smoothly continue power reduction to reach idle just prior to touchdown.
• Note •
The following factors are to be applied to the computed landing distance for
the noted condition:
• Headwind - Subtract 10% from table distances for each 13 knots headwind.
• Tailwind - Add 10% to table distances for each 2 knots tailwind up to 10 knots.
• Grass Runway, Dry - Add 20% to ground roll distance.
• Grass Runway, Wet - Add 60% to ground roll distance.
• Sloped Runway - Increase table distances by 27% of the ground roll distance for
each 1% of downslope. Decrease table distances by 9% of the ground roll
distance for each 1% of upslope.
• Caution •
The above corrections for runway slope are required to be included herein.
These corrections should be used with caution since published runway slope
data is usually the net slope from one end of the runway to the other. Many
runways will have portions of their length at greater or lesser slopes than the
published slope, lengthening (or shortening) landing ground roll estimated
from the table.
• For operation in outside air temperatures colder than this table provides, use
coldest data shown.
• For operation in outside air temperatures warmer than this table provides, use
extreme caution.

Airplane Weighing Procedures
A basic empty weight and center of gravity were established for this
airplane when the airplane was weighed just prior to initial delivery.
However, major modifications, loss of records, addition or relocation of
equipment, accomplishment of service bulletins, and weight gain over
time may require re-weighing to keep the basic empty weight and
center of gravity current. The frequency of weighing is determined by
the operator. All changes to the basic empty weight and center of
gravity are the responsibility of the operator. Refer to Section 8 for
specific servicing procedures.
1. Preparation:
a. Inflate tires to recommended operating pressures.
b.
Service brake reservoir.
c.
Drain fuel system.
d. Service engine oil.
e. Move crew seats to the most forward position.
f.
Raise flaps to the fully retracted position.
g. Place all control surfaces in neutral position.
h. Verify equipment installation and location by comparison to
equipment list.
2. Leveling (Figure 6-2):
a. Level longitudinally with a spirit level placed on the pilot door
sill and laterally with of a spirit level placed across the door
sills. Alternately, level airplane by sighting the forward and aft
tool holes along waterline 95.9.
b.
Place scales under each wheel (minimum scale capacity, 500
pounds nose, 1000 pounds each main).
c.
Deflate the nose tire and/or shim underneath scales as
required to properly center the bubble in the level.
3. Weighing (Figure 6-3):
a. With the airplane level, doors closed, and brakes released,
record the weight shown on each scale. Deduct the tare, if
any, from each reading.

Section 6
Weight & Balance
Cirrus Design

4. Measuring (Figure 6-3):
a. Obtain measurement ‘x’ by measuring horizontally along the
airplane center line (BL 0) from a line stretched between the
main wheel centers to a plumb bob dropped from the forward
side of the firewall (FS 100). Add 100 to this measurement to
obtain left and right weighing point arm (dimension ‘A’).
Typically, dimension ‘A’ will be in the neighborhood of 157.5.
b.
Obtain measurement ‘y’ by measuring horizontally and
parallel to the airplane centerline (BL 0), from center of
nosewheel axle, left side, to a plumb bob dropped from the
line stretched between the main wheel centers. Repeat on
right side and average the measurements. Subtract this
measurement from dimension ‘A’ to obtain the nosewheel
weighing point arm (dimension ‘B’).
5. Determine and record the moment for each of the main and nose
gear weighing points using the following formula:
Moment = Net Weight x Arm
6. Calculate and record the as-weighed weight and moment by
totaling the appropriate columns.
7. Determine and record the as-weighed C.G. in inches aft of datum
using the following formula:
C.G. = Total Moment / Total Weight
8. Add or subtract any items not included in the as-weighed condition
to determine the empty condition. Application of the above C.G.
formula will determine the C.G for this condition.
9. Add the correction for engine oil (15 lb at FS 78.4), if the airplane
was weighed with oil drained. Add the correction for unusable fuel
(18.0 lb at FS 154.9) to determine the Basic Empty Weight and
Moment. Calculate and record the Basic Empty Weight C.G. by
applying the above C.G. formula.
10. Record the new weight and C.G. values on the Weight and
Balance Record.

Weight & Balance
The above procedure determines the airplane Basic Empty Weight,
moment, and center of gravity in inches aft of datum. C.G. can also be
expressed in terms of its location as a percentage of the airplane
Mean Aerodynamic Cord (MAC) using the following formula:
C.G. % MAC = 100 x (C.G. Inches – LEMAC) / MAC
Where:
LEMAC = 133.1
MAC = 47.7

Loading Instructions
It is the responsibility of the pilot to ensure that the airplane is properly
loaded and operated within the prescribed weight and center of gravity
limits. The following information enables the pilot to calculate the total
weight and moment for the loading. The calculated moment is then
compared to the Moment Limits chart or table for a determination of
proper loading.
Airplane loading determinations are calculated using the Weight &
Balance Loading Form (Figure 6-6), the Loading Data chart and table
(Figure 6-7), and the Moment Limits chart and table (Figure 6-8).
1. Basic Empty Weight – Enter the current Basic Empty Weight and
Moment from the Weight & Balance Record.
2. Front Seat Occupants – Enter the total weight and moment/1000
for the front seat occupants from the Loading Data.
3. Rear Seat Occupants – Enter the total weight and moment/1000
for the rear seat occupants from the Loading Data.
4. Baggage – Enter weight and moment for the baggage from the
Loading Data.
• If desired, subtotal the weights and moment/1000 from steps 1
through 4. This is the Zero Fuel Condition. It includes all useful
load items excluding fuel.
5. Fuel Loading – Enter the weight and moment of usable fuel
loaded on the airplane from the Loading Data.
• Subtotal the weight and moment/1000. This is the Ramp
Condition or the weight and moment of the aircraft before taxi.
6. Fuel for start, taxi, and runup – This value is pre-entered on the
form. Normally, fuel used for start, taxi, and runup is approximately
9 pounds at an average moment/1000 of 1.394.
7. Takeoff Condition – Subtract the weight and moment/1000 for
step 8 (start, taxi, and runup) from the Ramp Condition values
(step 7) to determine the Takeoff Condition weight and moment/
1000.
• The total weight at takeoff must not exceed the maximum
weight limit of 3400 pounds.

Airframe
Fuselage
The SR22 monocoque fuselage is constructed primarily of composite
materials and is designed to be aerodynamically efficient. The cabin
area is bounded on the forward side by the firewall at fuselage station
100, and on the rear by the aft baggage compartment bulkhead at
fuselage station 222. Comfortable seating is provided for four adults. A
composite roll cage within the fuselage structure provides roll
protection for the cabin occupants. The cabin and baggage
compartment floors are constructed of a foam core composite with
access to under-floor components.
All flight and static loads are transferred to the fuselage structure from
the wings and control surfaces through four wing attach points in two
locations under the front seats and two locations on the sidewall just
aft of the rear seats.
Serials 0795, 0820 and subsequent: The lower firewall employes a 20°
bevel to improve crashworthiness. In addition, an avionics bay is
located aft of bulkhead 222 and accessible through an access panel
installed on the RH side of the aft fuselage.
• Note •
Refer to Airplane Cabin description in this section for a
complete description of doors, windows, baggage
compartment, seats, and safety equipment.
Wings
The wing structure is constructed of composite materials producing
wing surfaces that are smooth and seamless. The wing cross section
is a blend of several high performance airfoils. A high aspect ratio
results in low drag. Each wing provides attach structure for the main
landing gear and contains a 42-gallon fuel tank.
The wing is constructed in a conventional spar, rib, and shear section
arrangement. The upper and lower skins are bonded to the spar, ribs,
and shear sections (rear spars) forming a torsion box that carries all of
the wing bending and torsion loads. The wing spar is manufactured in
one piece and is continuous from wing tip to wing tip. The shear webs
(rear spars) are similar in construction but do not carry through the

fuselage. The main wing spar passes under the fuselage below the
two front seats and is attached to the fuselage in two locations. The
rear shear webs are attached to the fuselage sidewalls just aft of the
rear seats.
Empennage
The empennage consists of a horizontal stabilizer, a two-piece
elevator, a vertical fin and a rudder. All of the empennage components
are conventional spar (shear web), rib, and skin construction.
The horizontal stabilizer is a single composite structure from tip to tip.
The two-piece elevator, attached to the horizontal stabilizer, is
aluminum.
The vertical stabilizer is composite structure integral to the main
fuselage shell for smooth transfer of flight loads. The rudder is
aluminum and is attached to the vertical stabilizer rear shear web at
three hinge points.

Flight Controls
The SR22 uses conventional flight controls for ailerons, elevator and
rudder. The control surfaces are pilot controlled through either of two
single-handed side control yokes mounted beneath the instrument
panel. The location and design of the control yokes allow easy, natural
use by the pilot. The control system uses a combination of push rods,
cables and bell cranks for control of the surfaces.
Roll trim and pitch trim are available through an electric button on the
top of each control yoke. Electric yaw trim, if installed, is accomplished
by operating a switch on the forward console immediately to the left of
the Flaps switch.
Elevator System
The two-piece elevator provides airplane pitch control. The elevator is
of conventional design with skin, spar and ribs manufactured of
aluminum. Each elevator half is attached to the horizontal stabilizer at
two hinge points and to the fuselage tailcone at the elevator control
sector.
Elevator motion is generated through the pilot's control yokes by
sliding the yoke tubes forward or aft in a bearing carriage. A push-pull
linkage is connected to a cable sector mounted on a torque tube. A
single cable system runs from the forward elevator sector under the
cabin floor to the aft elevator sector pulley. A push-pull tube connected
to the aft elevator sector pulley transmits motion to the elevator
bellcrank attached to the elevators.

Aileron System
The ailerons provide airplane roll control. The ailerons are of
conventional design with skin, spar and ribs manufactured of
aluminum. Each aileron is attached to the wing shear web at two hinge
points.
Aileron control motion is generated through the pilot's control yokes by
rotating the yokes in pivoting bearing carriages. Push rods link the
pivoting carriages to a centrally located pulley sector. A single cable
system runs from the sector to beneath the cabin floor and aft of the
rear spar. From there, the cables are routed in each wing to a vertical
sector/crank arm that rotates the aileron through a right angle conical
drive arm.

Rudder System
The rudder provides airplane directional (yaw) control. The rudder is of
conventional design with skin, spar and ribs manufactured of
aluminum. The rudder is attached to the aft vertical stabilizer shear
web at three hinge points and to the fuselage tailcone at the rudder
control bell crank.
Rudder motion is transferred from the rudder pedals to the rudder by a
single cable system under the cabin floor to a sector next to the
elevator sector pulley in the aft fuselage. A push-pull tube from the
sector to the rudder bell crank translates cable motion to the rudder.
Springs and a ground adjustable spring cartridge connected to the
rudder pedal assembly tension the cables and provide centering force.
A rudder-aileron interconnect is installed to provide a maximum of 5°
down aileron with full rudder deflection. Right rudder input will cause
right roll input and left rudder input will cause left roll input. With
neutral aileron trim, aileron inputs will not cause rudder deflection.
On some airplanes, an electrically operated trim tab on the trailing
edge of the rudder allows pilot-operated rudder trim. Airplanes without
electric rudder trim have a ground adjustable trim tab installed.
Control Locks
The Cirrus SR22 control system is not equipped with gust locks. The
trim spring cartridges have sufficient power to act as a gust damper
without rigidly locking the position.

Trim Systems
Roll and pitch trim are provided by adjusting the neutral position of a
compression spring cartridge in each control system by means of an
electric motor. The electric roll trim is also used by the autopilot to
position the ailerons. An electrically actuated trim tab on the rudder, if
installed, provides rudder trim. It is possible to easily override full trim
or autopilot inputs by using normal control inputs.
Ground adjustable trim tabs are installed on the elevator and right
aileron to provide small adjustments in neutral trim. On airplanes
without electric rudder trim, a ground adjustable trim tab is installed on
the rudder. These tabs are factory set and do not normally require
adjustment.
Pitch Trim Control System
An electric motor changes the neutral position of the spring cartridge
attached to the elevator control horn. A conical trim button located on
top of each control yoke controls the motor. Moving the switch forward
will initiate nose-down trim and moving the switch aft will initiate noseup trim. Neutral (takeoff) trim is indicated by the alignment of a
reference mark on the yoke tube with a tab attached to the instrument
panel bolster. The elevator trim also provides a secondary means of
aircraft pitch control in the event of a failure in the primary pitch control
system not involving a jammed elevator. Elevator (pitch) trim operates
on 28 VDC supplied through the 2-amp PITCH / YAW TRIM circuit
breaker on Main Bus 1.
Roll Trim Control System
An electric motor changes the neutral position of a spring cartridge
attached to the left actuation pulley in the wing. A conical trim button
located on top of each control yoke controls the motor. Moving the
switch left will initiate left-wing-down trim and moving the switch right
will initiate right-wing-down trim. Neutral trim is indicated by the
alignment of the line etched on the control yoke with the centering
indication marked on the instrument panel. The aileron trim also
provides a secondary means of aircraft roll control in the event of a
failure in the primary roll control system not involving jammed ailerons.
Aileron trim operates on 28 VDC supplied through the 2-amp ROLL
TRIM circuit breaker on Main Bus 1.

Airplane Description
Yaw Trim System
Yaw trim is provided by spring cartridge attached to the rudder pedal
torque tube and console structure. The spring cartridge provides a
centering force regardless of the direction of rudder deflection. The
yaw trim is ground adjustable only.
On airplanes with electric rudder (yaw) trim, trim changes are pilot
controlled through a linear actuator connected to a hinged trim tab on
the rudder trailing edge. The actuator is installed in the rudder. A
RUDDER TRIM indicator with integral rocker switch is mounted in the
console immediately adjacent to the FLAP control switch. Pressing the
left half of the switch initiates Nose L trim and pressing the right half
initiates Nose R trim. A needle sweeps the trim indicator scale to
indicate trim position. The full Nose Right trim tic is labeled TAKEOFF.
Rudder (yaw) trim operates on 28 VDC supplied through the 2-amp
PITCH / YAW TRIM circuit breaker on Main Bus 1. The switch and
indicator are not internally illuminated.

Primary Flight Display - Serials 0435 and Subsequent
The Primary Flight Display (PFD) provides the functions of the attitude
indicator, heading indicator, airspeed indicator, altimeter, vertical
speed indicator, directional gyro, course deviation indicator, and
altitude pre-select controller onto a single electronic display. In
addition, the PFD communicates with GPS1, GPS2, NAV1, NAV2, the
Multifunction Display, and Autopilot System.
An integral air data/attitude and heading reference system (ADAHRS)
uses a 3-axis solid state gyro and accelerometer system combined
with a magnetometer to replace the vertical and directional gyros.
ADAHRS also provides roll, pitch, heading data and continually
updates the winds aloft and true airspeed (TAS) indications on the
PFD. The magnetometer assembly mounted in the wing also provides
outside air temperature (OAT) data.
The airplane’s Pitot-Static system is connected to the PFD to provide
airspeed, altitude, and vertical speed.
Standby instruments for airspeed, attitude and altitude are mounted on
the LH bolster panel and are on separate power sources than the PFD.
Redundant power sources provide 28 VDC for system operation.
Power is supplied through the 10-amp PFD1 circuit breaker on the
Essential Bus and the 10-amp PFD2 circuit breaker on Main Bus 2.
Either circuit is capable of powering the PFD. System start-up is
automatic once power is applied. The display presents the Initialization
Display immediately after power is applied. Power-on default is 75%
brightness. Typical alignment times are 3 minutes from battery turn on.

Horizontal Situation Indicator (HSI)
Heading Data
Magnetic heading is represented in boxed numeric form at the top of
the compass rose. Heading rate (Rate of Turn Indicator) takes the form
of a blue arcing arrow that begins behind the magnetic heading
indicator and moves left or right accordingly. Graduations are provided
on the rate-of-turn indicator scale to indicate half and full standard-rate
turns. A heading bug is also provided on the compass rose.
Navigation Data
Navigation data on the PFD takes several forms. A course deviation
indicator (CDI) is always provided on the HSI and a bearing pointer
can be optionally selected for display on the HSI by the pilot. Controls
for selecting the source of navigation data, selecting the display format
of the navigation data, and for selecting the type of compass rose and
moving map to be displayed are along the left side of the PFD. The
active flight plan contained in the GPS Nav/Com unit selected as the
primary navigation source (Nav) can be optionally selected for display
on the HSI as well as the desired range of the optionally selectable
moving map display. If a localizer or ILS frequency is tuned and
captured in the GPS Nav/Com selected as the Nav source, a vertical
deviation indicator (VDI) and horizontal deviation indicator (HDI) are
automatically displayed on the ADI.
• Note •
In the event glide slope or localizer signals are lost, the HDI
and/or VDI will be displayed as red-“X”s to indicate loss of
signal. The red-“X”-ed indicator will only be removed if the
signal is regained, the Nav Source is changed on the PFD, or
if the GPS Nav/Com is retuned to another frequency.
Appropriate action must be taken by the pilot if on an
approach.
For a detailed description of the PFD, refer to the Avidyne FlightMax
Entegra-Series PFD Pilot’s Guide.

Attitude Indicator
• Note •
Serials 0435 and subsequent with PFD: The attitude indicator
is mounted on the LH bolster panel.
The attitude indicator gives a visual indication of flight attitude. Bank
attitude is indicated by a pointer at the top of the indicator relative to
the bank scale with index marks at 10°, 20°, 30°, 60°, and 90° either
side of the center mark. A fixed miniature airplane superimposed over
a movable mask containing a white symbolic horizon bar, which
divides the mask into two sections, indicates pitch and roll attitudes.
The upper “blue sky” section and the lower “earth” sections have pitch
reference lines useful for pitch attitude control. The indicator can follow
maneuvers through 360° in roll and 360° in pitch. A knob at the bottom
of the instrument allows adjustment of the miniature airplane to the
horizon bar for a more accurate flight attitude indication.
A PULL TO CAGE knob on the indicator is used for quick erection of
the gyro. When the caging knob is pulled, the pitch and roll indications
will align to within 2° of their respective fixed references.
The instrument is electrically driven and a red GYRO flag indicates
loss of electrical power. Redundant circuits paralleled through diodes
at the indicator supply DC electrical power for gyro operation. 28 VDC
for attitude gyro operation is supplied through the 3-amp Attitude #1
circuit breaker on the Essential Bus and the 3-amp Attitude #2 circuit
breaker on the Main Bus 2.

reference pressure and displays the result in climb or descent feet per
minute (FPM). Climb is indicated by clockwise rotation of the pointer
from zero and descent is indicated by counter clockwise rotation. The
'0' (zero) reference point is at the 9 o'clock position. The scale is
calibrated from 0 to 2000 FPM in 100-FPM increments in both the 'UP'
and 'DOWN' directions.
Altimeter
• Note •
Serials 0435 and subsequent with PFD: The standby altimeter
is mounted on the LH bolster panel.
Airplane altitude is depicted on a conventional, three-pointer, internally
lit barometric altimeter installed in the pilot's instrument panel. The
instrument senses the local barometric pressure adjusted for altimeter
setting and displays the result on the instrument in feet. The altimeter
is calibrated for operation between -1000 and 20,000 feet altitude. The
scale is marked from 0 to 10 in increments of 2. The long pointer
indicates hundreds of feet and sweeps the scale every 1000 feet (each
increment equals 20 feet). The short, wide pointer indicates thousands
of feet and sweeps the scale every 10,000 feet (each increment equals
200 feet). The short narrow pointer indicates tens of thousands feet
and sweeps from 0 (zero) to 2 (20,000 feet with each increment equal

Wing Flaps
The electrically controlled, single-slotted flaps provide low-speed lift
enhancement. Each flap is manufactured of aluminium and connected
to the wing structure at three hinge points. Rub strips are installed on
the top leading edge of each flap to prevent contact between the flap
and wing flap cove. The flaps are selectively set to three positions: 0%,
50% (16° ) and 100% (32° ) by operating the FLAP control switch. The
FLAP control switch positions the flaps through a motorized linear
actuator mechanically connected to both flaps by a torque tube.
Proximity switches in the actuator limit flap travel to the selected
position and provide position indication. The wing flaps and control
circuits are powered by 28 VDC through the 15-amp FLAPS circuit
breaker on the Non-Essential Bus.
Flap Control Switch
An airfoil-shaped FLAPS control switch is located at the bottom of the
vertical section of the center console. The control switch is marked
and has detents at three positions: UP (0%), 50% and 100% (Down).
The appropriate VFE speed is marked at the Flap 50% and 100%
switch positions. Setting the switch to the desired position will cause
the flaps to extend or retract to the appropriate setting. An indicator
light at each control switch position illuminates when the flaps reach
the selected position. The UP (0%) light is green and the 50% and
FULL (100%) lights are yellow.

belts are attached to fittings on the floorboard and the forward seat
belts are attached to the seat frame. The shoulder harnesses are
attached to inertia reels mounted in the seat back for the front seats
and on the baggage compartment rear bulkhead for the rear seats.
Each harness is attached to the seat belt. The buckle half of each
assembly is on the left-hand side and the link half is on the right-hand
side. The inertia reels allow complete freedom of movement of the
occupant’s upper torso. In the event of a sudden deceleration, the
reels lock automatically to protect the occupants. It is recommended
that the seat belts be stowed in the latched position when not in use.
Serials 0002 through 1499, 1501 through 1519 after SB 2X-25-14 and
serials 1500, 1520 and subsequent; An inflatable shoulder harness is
integral to each crew seat harness. The electronic module assembly,
mounted below the cabin floor, contains a crash sensor, battery, and
related circuitry to monitor the deceleration rate of the airplane. In the
event of a crash, the sensor evaluates the crash pulse and sends a
signal to an inflator assembly mounted to the aft seat frame. This
signal releases the gas in the inflator and rapidly inflates the airbag
within the shoulder harness cover, After airbag deployment, the airbag
deflates to enable the pilot/co-pilot to egress the aircraft without
obstruction.
The crash sensor’s predetermined deployment threshold does not
allow inadvertent deployment during normal operations, such as hard
landings, strikes on the seat, or random vibration.
• Caution •
No slack may exist between the occupant’s shoulder and
restraint harness shoulder strap.
Stow the seat belts in the latched position when not in use.

The extinguisher must be visually inspected before each flight to
assure that it is available, charged, and operable. The preflight
inspection consists of ensuring that the nozzle is unobstructed, the pin
has not been pulled, and the canister has not been damaged.
Additionally, the unit should weigh approximately 1.5 lb (0.7 kg). For
preflight, charge can be determined by ‘hefting’ the unit.

Airplane Description
Engine
The SR22 is powered by a Teledyne Continental IO-550-N, sixcylinder, normally aspirated, fuel-injected engine rated to 310 hp at
2700 RPM. The engine has a 2000-hour Time Between Overhaul
(TBO). Dual, conventional magnetos provide ignition.
Serials 0002 through 0819 before Service Bulletin SB 2X-71-06; The
engine is attached to the firewall by a four-point steel engine mount.
Serials 0002 through 0819 after Service Bulletin SB 2X-71-06 and
airplane serials 0820 and subsequent: The engine is attached to the
firewall by a six-point steel engine mount.
The firewall attach points are structurally reinforced with gusset-type
attachments that transfer thrust and bending loads into the fuselage
shell.
Engine Oil System
The engine is provided with a wet-sump, high-pressure oil system for
engine lubrication and cooling. Oil for engine lubrication is drawn from
an eight-quart capacity sump through an oil suction strainer screen
and directed through the oil filter to the engine-mounted oil cooler by a
positive displacement oil pump. The oil pump is equipped with a
pressure relief valve at the pump output end to bypass oil back to the
pump inlet should the pump exceed limits. The oil cooler is equipped
with a temperature control valve set to bypass oil if the temperature is
below 180°F (82° C). Bypass or cooled oil is then directed through oil
galleries to the engine rotating parts and piston inner domes. Oil is
also directed to the propeller governor to regulate propeller pitch. The
complete oil system is contained in the engine. An oil filler cap and
dipstick are located at the left rear of the engine. The filler cap and
dipstick are accessed through a door on the top left side of the engine
cowling.
• Caution •
The engine should not be operated with less than six quarts of
oil. Seven quarts (dipstick indication) is recommended for
extended flights.

Engine Cooling
Engine cooling is accomplished by discharging heat to the oil and then
to the air passing through the oil cooler, and by discharging heat
directly to the air flowing past the engine. Cooling air enters the engine
compartment through the two inlets in the cowling. Aluminum baffles
direct the incoming air to the engine and over the engine cylinder
cooling fins where the heat transfer takes place. The heated air exits
the engine compartment through two vents in the aft portion of the
cowling. No movable cowl flaps are used.
Engine Fuel Injection
The multi-nozzle, continuous-flow fuel injection system supplies fuel
for engine operation. An engine driven fuel pump draws fuel from the
selected wing tank and passes it to the mixture control valve integral to
the pump. The mixture control valve proportions fuel in response to the
pilot operated mixture control lever position. From the mixture control,
fuel is routed to the fuel-metering valve on the air-induction system
throttle body. The fuel-metering valve adjusts fuel flow in response to
the pilot controlled Power Lever position. From the metering valve, fuel
is directed to the fuel manifold valve (spider) and then to the individual
injector nozzles. The system meters fuel flow in proportion to engine
RPM, mixture setting, and throttle angle. Manual mixture control and
idle cut-off are provided. An electric fuel pump provides fuel boost for
vapor suppression and for priming.
Engine Air Induction System
Induction air enters the engine compartment through the two inlets in
the forward cowling. The air passes through a dry-foam induction filter,
through the throttle butterfly, into the six-tube engine manifold, and
finally through the cylinder intake ports into the combustion chambers.
Should the dry induction filter become clogged, a pilot controlled
alternate induction air door can be opened, allowing engine operation
to continue. Refer to Engine Controls, Alternate Air Control.
Engine Fuel Ignition
Two engine-driven magnetos and two spark plugs in each cylinder
provide fuel ignition. The right magneto fires the lower right and upper
left spark plugs, and the left magneto fires the lower left and upper
7-42

Airplane Description
right spark plugs. Normal operation is conducted with both magnetos,
as more complete burning of the fuel-air mixture occurs with dual
ignition.
Engine Exhaust
Engine exhaust gases are routed through a tuned exhaust system.
After leaving the cylinders, exhaust gases are routed through the
exhaust manifold, through a muffler located on the right side of the
engine or, airplane serials 0320 and subsequent, through mufflers
located on either side of the engine, then overboard through an
exhaust pipe(s) exiting through the lower cowling. A muff type heat
exchanger, located around the right muffler, provides cabin heat.
Engine Controls
Engine controls are easily accessible to the pilot on a center console.
They consist of a single-lever power (throttle) control and a mixture
control lever. A friction control wheel, labeled FRICTION, on the right
side of the console is used to adjust control lever resistance to rotation
for feel and control setting stability. An alternate induction air source
control is also provided.
Power (Throttle) Lever
The single-lever throttle control, labeled MAX-POWER-IDLE, on the
console adjusts the engine throttle setting in addition to automatically
adjusting propeller speed. The lever is mechanically linked by cables
to the air throttle body/fuel-metering valve and to the propeller
governor. Moving the lever towards MAX opens the air throttle butterfly
and meters more fuel to the fuel manifold. A separate cable to the
propeller governor adjusts the governor oil pressure to increase
propeller pitch to maintain engine RPM. The system is set to maintain
approximately 2500 RPM throughout the cruise power settings and
2700 RPM at full power.
Mixture Control
The mixture control lever, labeled RICH-MIXTURE-CUTOFF, on the
console adjusts the proportion of fuel to air for combustion. The
Mixture Control Lever is mechanically linked to the mixture control
valve in the engine-driven fuel pump. Moving the lever forward
(towards RICH) repositions the valve allowing greater proportions of
fuel and moving the lever aft (towards CUTOFF) reduces (leans) the

valve.
Start/Ignition Switch
• Note •
Airplane serials 0435 and subsequent with PFD: The Start/
Ignition Switch is located on the instrument panel.
A rotary-type key switch, located on the left bolster, controls ignition
and starter operation. The switch is labeled OFF-R-L- BOTH-START.
In the OFF position, the starter is electrically isolated, the magnetos
are grounded and will not operate. Normally, the engine is operated on
both magnetos (switch in BOTH position) except for magneto checks
and emergency operations. The R and L positions are used for
individual magneto checks and for single magneto operation when
required. When the battery master switch is ON, rotating the switch to
the spring loaded START position energizes the starter and activates
both magnetos. The switch automatically returns to the BOTH position
when released.
Alternate Air Control
An Alternate Induction Air Control knob, labeled ALT AIR – PULL, is
installed on the left console near the pilot’s right ankle. To operate the
control, depress the center lock button, pull the knob to the open
position, and then release the lock button. Pulling the knob opens the
alternate air induction door on the engine induction air manifold,
bypasses the air filter, and allows warm unfiltered air to enter the
engine. Alternate induction air should be used if blocking of the normal
air source is suspected. Operation using alternate induction air should
be minimized and the cause of filter blocking corrected as soon as
practical.
Engine Indicating
The SR22 is equipped with engine instrumentation and warning lights
to monitor the engine performance.

Airplane Description
Propeller
The airplane is equipped with a constant-speed, aluminum-alloy
propeller with a three-blade (78" diameter) propeller and governor.
The propeller governor automatically adjusts propeller pitch to
regulate propeller and engine RPM. The propeller governor senses
engine speed by means of flyweights and senses throttle setting
through a cable connected to the power (throttle) control lever in the
cockpit. The propeller governor boosts oil pressure in order to regulate
propeller pitch position. Moving the throttle lever forward causes the
governor to meter less high-pressure oil to the propeller hub allowing
centrifugal force acting on the blades to lower the propeller pitch for
higher RPM operation. Reducing the power (throttle) lever position
causes the governor to meter more high-pressure oil to the propeller
hub forcing the blades to a higher pitch, lower RPM, position. During
stabilized flight, the governor automatically adjusts propeller pitch in
order to maintain an RPM setting (throttle position). Any change in
airspeed or load on the propeller results in a change in propeller pitch.

Fuel System
An 81-gallon usable wet-wing fuel storage system provides fuel for
engine operation. The system consists of a 42-gallon capacity (40.5gallon usable) vented integral fuel tank and a fuel collector/sump in
each wing, a three position selector valve, an electric boost pump, and
an engine-driven fuel pump. Fuel is gravity fed from each tank to the
associated collector sumps where the engine-driven fuel pump draws
fuel through a filter and selector valve to pressure feed the engine fuel
injection system. The electric boost pump is provided for engine
priming and vapor suppression.
Each integral wing fuel tank has a filler cap in the upper surface of
each wing for fuel servicing. Access panels in the lower surface of
each wing allow access to the associated wet compartment (tank) for
inspection and maintenance. Float-type fuel quantity sensors in each
wing tank and each collector tank supply fuel level information to the
fuel quantity indicators. Positive pressure in the tank is maintained
through a vent line from each wing tank. Fuel, from each wing tank,
gravity feeds through strainers and a flapper valve to the associated
collector tank in each wing. Each collector tank/sump incorporates a
flush mounted fuel drain and a vent to the associated fuel tank.
The engine-driven fuel pump pulls filtered fuel from the two collector
tanks through a three-position (LEFT-RIGHT-OFF) selector valve. The
selector valve allows tank selection. From the fuel pump, the fuel is
proportioned to the induction airflow, metered to a flow divider, and
delivered to the individual cylinders. Excess fuel is returned to the
selected tank.
A dual-reading fuel-quantity indicator is located in the center console
next to the fuel selector in plain view of the pilot. Fuel shutoff and tank
selection is positioned nearby for easy access.
Fuel system venting is Essential to system operation. Blockage of the
system will result in decreasing fuel flow and eventual engine fuel
starvation and stoppage. Venting is accomplished independently from
each tank by a vent line leading to a NACA-type vent mounted in an
access panel underneath the wing near each wing tip.

The airplane may be serviced to a reduced capacity to permit heavier
cabin loadings. This is accomplished by filling each tank to a tab
visible below the fuel filler, giving a reduced fuel load of 23.5 gallons
usable in each tank (47 gallons total usable in all flight conditions).
Drain valves at the system low points allow draining the system for
maintenance and for examination of fuel in the system for
contamination and grade. The fuel must be sampled prior to each
flight. A sampler cup is provided to drain a small amount of fuel from
the wing tank drains, the collector tank drains, and the gascolator
drain. If takeoff weight limitations for the next flight permit, the fuel
tanks should be filled after each flight to prevent condensation.

Fuel Quantity Indicator
A dual reading 2¼” fuel quantity indicator is installed on the console
immediately forward of the fuel selector valve. The LEFT pointer
indicates left tank fuel quantity and sweeps a scale marked from 0 to
41 U.S. gallons in 5-gallon increments. The RIGHT pointer sweeps an
identical scale for the right tank. Each scale is marked with a yellow
arc from 0 to 14 U.S. gallons. The indicators are calibrated to read '0'
when no usable fuel remains. Each indicator also provides an output
signal to illuminate the FUEL caution light when the fuel quantity goes
below approximately 14 gallons in each tank. The fuel quantity

Manifold Pressure Gage. Refer to preceding discussion on Fuel Flow
and Manifold Pressure Gage for complete description of fuel flow
indication.
Serials 1602, 1644, 1663 and subsequent: Fuel flow is shown as text
in the fuel data block located in the lower right section of the MFD and
is also continuously displayed in the engine data block located in the
lower right corner of the PFD. The MFD and PFD receives a fuel-flow
rate signal via the DAU from a fuel-flow transducer on the right side of
the engine in the fuel line between the engine driven fuel pump and
throttle body metering valve.
In the event fuel flow exceeds 30.0 gallons per hour, the MFD will
display “Check Fuel Flow” in a red advisory box in the lower right
corner of the MFD.
28 VDC for the digital instrument operation is supplied through the 2amp ANNUN / ENGINE INST circuit breaker on the Essential Bus.
Fuel Caution Light
The amber FUEL caution light in the annunciator panel comes on to
indicate a low fuel condition. The light is illuminated by switches in the
fuel quantity indicator if the fuel quantity in both tanks drops below
approximately 14 gallons (28 gallons total with tanks balanced in level
flight). Since both tanks must be below 14 gallons to illuminate the
light, the light could illuminate with as little as 14 gallons in one tank
during level flight if the other tank is allowed to run dry. If the FUEL
caution light comes on in flight, refer to the Fuel Quantity gages to
determine fuel quantity. The light is powered by 28 VDC through the 2amp ANNUN / ENGINE INST circuit breaker on the Essential Bus.

Boost Pump Switch
Boost pump operation and engine prime is controlled through the Fuel
Pump BOOST-PRIME switch located adjacent to the fuel selector
valve. The PRIME position is momentary and the BOOST position is
selectable. A two-speed prime allows the fuel pressure to rapidly
achieve proper starting pressure.
Serials 0002 through 0277 before SB 22-73-01: For engine starting,
pressing PRIME causes the boost pump to operate at high speed until
the fuel pressure reaches 2-4 psi. When the fuel pressure reaches the
2-4 psi range, a pressure switch in the fuel injection line switches the
boost pump to the low-speed mode to provide a 4-6 psi fuel pressure
boost. Selecting BOOST energizes the boost pump in low-speed
mode to deliver a continuous 4-6 psi boost to the fuel flow for vapor
suppression in a hot fuel condition.
Serials 0278 and subs, and serials 0002 through 0277 after SB 22-7301: An oil pressure based system is used to control boost pump
operation. The oil pressure/oil temperature sensor provides a signal to
the starting circuit/DAU to generate a ground for the oil annunciator
and the fuel system. This system allows the fuel pump to run at high
speed (PRIME) when the engine oil pressure is less than 10 PSI.
Whenever the engine oil pressure exceeds 10 PSI, pressing PRIME
will have no effect. Selecting BOOST energizes the boost pump in lowspeed mode regardless of oil pressure to deliver a continuous 4-6 psi
boost to the fuel flow for vapor suppression in a hot fuel condition.
The boost pump operates on 28 VDC supplied through the 5-amp
FUEL PUMP circuit breaker on Main Bus 2.

Brake System
The main wheels have hydraulically operated, single-disc type brakes,
individually activated by floor mounted toe pedals at both pilot stations.
A parking brake mechanism holds induced hydraulic pressure on the
disc brakes for parking.
The brake system consists of a master cylinder for each rudder pedal,
a hydraulic fluid reservoir, a parking brake valve, a single disc brake
assembly on each main landing gear wheel, and associated hydraulic
plumbing. Braking pressure is initiated by depressing the top half of a
rudder pedal (toe brake). The brakes are plumbed so that depressing
either the pilot’s or copilot’s left or right toe brake will apply the
respective (left or right) main wheel brake. The reservoir is serviced
with Mil-H-5606 hydraulic fluid.
Brake system malfunction or impending brake failure may be indicated
by a gradual decrease in braking action after brake application, noisy
or dragging brakes, soft or spongy pedals, excessive travel, and/or
weak braking action. Should any of these symptoms occur, immediate
maintenance is required. If, during taxi or landing roll, braking action
decreases, let up on the toe brakes and then reapply the brakes with
heavy pressure. If the brakes are spongy or pedal travel increases,
pumping the pedals may build braking pressure.
Refer to Section 10, Safety Information, for Brake System operational
considerations.

Parking Brake
• Caution •
Do not pull the PARK BRAKE knob in flight. If a landing is
made with the parking brake valve set, the brakes will maintain
any pressure applied after touchdown.
The main wheel brakes are set for parking by using the PARK BRAKE
knob on the left side of the console near the pilot’s right ankle. Brake
lines from the toe brakes to the main wheel brake calipers are
plumbed through a parking brake valve. For normal operation, the
knob is pushed in. With the knob pushed in, poppets in the valve are
mechanically held open allowing normal brake operation. When the
handle is pulled out, the parking brake valve holds applied brake
pressure, locking the brakes. To apply the parking brake, set the
brakes with the rudder-pedal toe brakes, and then pull the PARK
BRAKE knob aft.

Airplane Description
Electrical System
The airplane is equipped with a two-alternator, two-battery, 28-volt
direct current (VDC) electrical system designed to reduce the risk of
electrical system faults. The system provides uninterrupted power for
avionics, flight instrumentation, lighting, and other electrically operated
and controlled systems during normal operation.
Power Generation
Primary power for the SR22 is supplied by a 28-VDC, negative-ground
electrical system. The electrical power generation system consists of
two alternators controlled by a Master Control Unit (MCU) mounted on
the left side of the firewall and two batteries for starting and electrical
power storage.
Alternator 1 (ALT 1) is a gear-driven, internally rectified, 60-amp
alternator mounted on the right front of the engine. Alternator 2 (ALT 2)
is a gear-driven, internally rectified, 20-amp alternator mounted on the
accessory drive at the rear of the engine. ALT 1 is regulated to 28 volts
and ALT 2 is regulated to 28.75 volts. The output from ALT 1 is
connected to the Main Distribution Bus in the MCU through an 80-amp
fuse. The output from ALT 2 is connected to the Essential Distribution
Bus in the MCU through a 40-amp fuse. Both alternators are selfexciting (not self-starting) and require battery voltage for field
excitation in order to start up - for this reason, the batteries should not
be turned off in flight.
Battery 1 (BAT 1) is an aviation grade 12-cell, lead-acid, 24-volt, 10amp-hour battery mounted on the right firewall. BAT 1 is charged from
the Main Distribution Bus in the MCU. Battery 2 (BAT 2) is composed
of two 12-volt, 7-amp-hour, sealed, lead-acid batteries connected in
series to provide 24 volts. Both BAT 2 units are located in a vented,
acid-resistant container mounted behind the aft cabin bulkhead (FS
222) below the parachute canister. BAT 2 is charged from the circuit
breaker panel Essential Bus.
The Master Control Unit (MCU) is located on the left firewall. The MCU
controls ALT 1, ALT 2, starter, landing light, external power, and power
generation functions. In addition to ALT 1 and ALT 2 voltage
regulation, the MCU also provides external power reverse polarity
protection, alternator overvoltage protection, as well as alternator fail

and overcurrent annunciations. Power is distributed to the airplane
circuit panel buses through Main and Essential buses in the MCU.
During normal operation, the alternators feed their respective
Distribution Bus independently (ALT 1 feeds Main Distribution Bus and
ALT 2 feeds the Essential Distribution Bus). The distribution busses
are interconnected by two 50-amp fuses and a diode. The diode
prevents ALT 2 from feeding the Main Distribution Bus. Additionally,
since ALT 2 / Essential Distribution Bus voltage is slightly higher than
ALT 1 / Main Distribution Bus voltage, ALT 1 will not feed the Essential
Distribution Bus unless ALT 2 fails.
Power Distribution
The power distribution system for the SR22 consists of the Main
Distribution Bus and the Essential Distribution Bus in the MCU and
associated buses in the Circuit Breaker panel. The circuit breaker
panel is located on the left side of the console next to the pilots right
knee.
For normal operation, the Essential Buses in the circuit breaker panel
are powered from the Essential Distribution Bus in the MCU through
25-amp circuit breakers. BAT 2 is connected directly to the Essential
Bus in the circuit breaker panel and will power the bus should the
voltage coming from the MCU distribution buses drop below the
battery voltage. Additionally, in the event of an ALT 2 failure, the circuit
breaker panel Essential Bus will be powered from ALT 1 through the
Main distribution and Essential distribution buses in the MCU. Main
Bus 1, Main Bus 2, and the equipment Non-Essential Bus in the circuit
breaker panel are powered from ALT 1 through the Main Distribution
Bus in the MCU. The Avionics Non-Essential Bus in the circuit breaker
panel is powered from Main Bus 1.

BAT & ALT Master Switches
The rocker type electrical system MASTER switches are ON in the up
position and OFF in the down position. The switches, labeled BAT 2,
BAT 1, ALT 1, ALT 2 are located in the bolster switch panel
immediately below the instrument panel. These switches, along with
the AVIONICS power switch, control all electrical power to the
airplane.
Battery Switches
The BAT 1 and BAT 2 switches control the respective battery. Setting
the BAT 1 switch 'on' energizes a relay connecting BAT 1 to the MCU
Distribution Buses (also energizing the circuit breaker panel buses)
and the open contacts of the starter relay. Setting the BAT 2 switch 'on'
energizes a relay connecting BAT 2 to the circuit breaker panel
Essential Buses. Normally, for flight operations, all master switches will
be 'on.' However, the BAT 1 and BAT 2 switches can be turned 'on'
separately to check equipment while on the ground. Setting only the
BAT 2 switch 'on' will energize those systems connected to the circuit
breaker panel Essential Bus. If any system on the other buses is
energized, a failure of the Distribution Bus interconnect isolation diode
is indicated. When the BAT 1 switch is set to 'on,' the remaining
systems will be energized. To check or use avionics equipment or
radios while on the ground, the AVIONICS power switch must also be
turned on.

Alternator Switches
The ALT 1 and ALT 2 switches control field power to the respective
alternator. For ALT 1 to start, the BAT 1 switch must be 'on.' Setting the
ALT 1 switch 'on' energizes a relay allowing 28 VDC from the ALT 1
circuit breaker (Main Bus 2) to be applied to voltage regulator for ALT
1. For ALT 2 to start, either the BAT 1 switch or the BAT 2 switch must
be 'on.' Setting the ALT 2 switch 'on' energizes a relay allowing 28
VDC from the ALT 2 circuit breaker (Essential Bus) to be applied to
voltage regulator for ALT 2. Positioning either ALT switch to the OFF
position removes the affected alternator from the electrical system.
• Note •
Continued operation with the alternators switched off will
reduce battery power low enough to open the battery relay,
remove power from the alternator field, and prevent alternator
restart.
Avionics Power Switch
A rocker switch, labeled AVIONICS, controls electrical power from the
circuit breaker panel bus to the Avionics Bus. The switch is located
next to the ALT and BAT Master switches. Typically, the switch is used
to energize or de-energize all avionics on the Avionics Non-Essential
and Essential Buses simultaneously. With the switch in the OFF
position, no electrical power will be applied to the avionics equipment,
regardless of the position of the master switch or the individual
equipment switches. For normal operations, the AVIONICS switch
should be placed in the OFF position prior to activating the MASTER
switches, starting the engine, or applying an external power source.
Volts and Ampere Meter/Indication
Serials 0002 through 1601, 1603 through 1643 and 1645 through
1662: A 2¼” combination Volts and Ampere meter is mounted on the
right instrument panel outboard of the oil temperature and pressure
indicator. The indicator is internally lighted. 28 VDC for instrument
lighting is supplied through the 2-amp INST LIGHTS circuit breaker on
Main Bus 1.
The VOLT pointer sweeps a scale from 16 to 32 volts. Refer to Section
2, Limitations, in basic POH for instrument limit markings. The voltage
indication is measured off the Essential Bus.

The AMP pointer sweeps a scale from -100 to +100 amps with zero at
the 9 o'clock position. The amps indication is derived from current
transducers located in the MCU. Output from each alternator and BAT
1 is measured. The panel mounted AMMETER SELECT switch is
used to select the desired indication. When the engine is operating
and the ALT 1 and ALT 2 Master switches are 'on,' the ammeter
indicates the charging rate applied to the batteries. In the event the
alternators are not functioning or the electrical load exceeds the output
of the alternators, the ammeter indicates BAT 1 discharge rate.
Alternator ammeter indications are positive only.

parameters block located in the upper left corner of the PFD when
voltages fall outside typical operating parameters. The MFD and PFD
receive the voltage signals via the DAU as measured directly off the
Main and Essential Buses.
In the event Main Bus voltage is less than 24.5v or exceeds 32.0v the
MFD will display “Check Main Bus” in a yellow advisory box in the
lower right corner of the MFD.
In the event Essential Bus voltage is less than 24.5v or exceeds 32.0v

Environmental System
Cabin heating and ventilation is accomplished by supplying
conditioned air for heating and windshield defrost and fresh air for
ventilation. Ventilation air is provided by ducting ram air from air inlets
to eyeball outlets for each occupant. Each occupant can direct the
fresh air flow by positioning the nozzle or control flow rate from 'off' to
maximum by rotating the nozzle.
Heating is accomplished by mixing ram air from the fresh air inlets with
heated air from the heat exchanger and then distributing the
'conditioned' air to the occupants and/or the windshield diffuser. Air for
heating is supplied by an inlet in the engine compartment to a mufftype heat exchanger surrounding the right engine exhaust muffler.
Conditioned air outlets for the forward occupants are directionally
controllable and are located beneath the instrument panel at each
position at knee level. Outlets for the rear occupants are at floor level.
The temperature, volume, and flow selection are regulated by
manipulation of the cabin temperature and cabin air selector knobs on
the lower right side of the instrument panel.

the windshield diffuser. Rotating the knob full clockwise shuts off
airflow to the windshield diffuser and allows maximum airflow to the
passenger air distribution system. The control can be positioned to
allow any proportion of windshield and passenger air. Conditioned air
for the forward seats is routed to outlets under the instrument panel at
knee level. Conditioned air for the aft seats is routed to outlets beneath
the forward seats near the door posts and exits at floor level.
Cabin Heat Control
The amount of heated air allowed into the air mixing plenum is
controlled by rotating the Cabin Heat Control. The control is
mechanically linked to a door in a heater box between the heater muff
and the mixing plenum. Rotating the control full counterclockwise
(HEAT OFF) bypasses heated air from the heater muff into the engine
compartment. Rotating the control clockwise opens the door in the
heater box allowing heated air to enter the mixing plenum.
Cabin Cooling Control
The amount of cooling air allowed into the air mixing plenum is
controlled by rotating the cabin cool control, located outboard of the
cabin air selector. The control is mechanically linked to a butterfly
valve at the fresh air entrance to the mixing plenum. Rotating the
control full counterclockwise shuts down cooling airflow to the mixing
plenum from the fresh air inlet in the right wing root. Rotating the
control clockwise opens the butterfly allowing fresh cooling air to enter
the mixing plenum. Rotating the knob to the full clockwise (COLD)
position provides maximum cooling airflow to the mixing plenum.

Distribution
Ventilation and cooling is provided by ducting fresh air from a NACA
inlet on the RH cowl to the mixing chamber located on the lower RH
portion of the firewall. Depending on operating mode and temperature
selection, the air in the mixing chamber is ducted directly into the
distribution system or, if in Air Conditioning mode (optional), is further
cooled as it passes through the evaporator assembly located under
the front passenger seat.
Heating is accomplished by mixing ventilation air from the fresh air
inlet with heated air provided by the heat exchanger in the mixing
chamber on the firewall. From the mixing chamber - which also
controls airflow into the cabin compartment - the conditioned air is
forced by ram air pressure or by blower fan into a distribution manifold
mounted to the center, aft side of the firewall. The distribution manifold
uses butterfly valves to control airflow to the floor and defrost vents.
Airflow is ducted directly to all panel air vents.
Crew panel air vents are located inboard on the RH and LH bolster
panels and on the outboard section of the instrument panel. The crew
floor air vents are mounted to the bottom of each kick plate. The
passenger panel air vents are chest high outlets mounted in the
armrests integral to the LH and RH cabin wall trim panels. The
passenger floor air vents are mounted to the bottom portion of the LH
and RH cabin wall trim panels. The windshield diffuser, located in the
glareshield assembly, directs conditioned air to the base of the
windshield.
Heating
Ram air from the NACA inlet flows through the upper cowl and is
ducted to the heat exchanger. The heated air is then routed to the hot
air valve, mounted to the forward side of the firewall, which controls
entry of hot air into the cabin distribution system. When the valve is
open, the air flows into the cabin mixing chamber. When the valve is
closed, the heated air exits into the engine compartment and is
exhausted overboard with the engine cooling airflow. Cabin heat is
regulated by controlling the volume of hot air admitted into the
distribution system’s air mixing chamber. The proportion of heated air
to fresh air is accomplished using the temperature selector mounted
on the RH instrument panel.

Airplane Description
Cooling
Standard cabin cooling is provided by ram air admitted through the
NACA inlet on the RH cowl to the fresh air valve, mounted to the
forward side of the firewall. When the fresh air valve is open, the air
flows into the cabin mixing chamber. When the fresh air valve is
closed, the cooled air exits into the engine compartment and is
exhausted overboard with the engine cooling airflow.
In Air Conditioning mode (optional), R134A refrigerant enters the
engine mounted compressor as a vapor and is pressurized until the
heat-laden vapor reaches a point much hotter than the outside air. The
compressor then pumps the vapor to the condenser where it cools,
changes to a liquid, and passes to the receiver-drier. The receiverdrier’s function is to filter, remove moisture, and ensure a steady flow
of liquid refrigerant into the evaporator through the expansion valve - a
temperature controlled metering valve which regulates the flow of
liquid refrigerant to the evaporator. Inside the evaporator, the liquid
refrigerant changes state to a gas and in doing so, absorbs heat. The
evaporator then absorbs the heat from the air passing over the coils
and the moisture from the air condenses and is drained overboard
through the belly of the aircraft. From the evaporator, the refrigerant
vapor returns to the compressor where the cycle is repeated. During
normal air conditioning operation, ram air from the fresh air intake
flows into the evaporator assembly, is cooled as it passes through the
evaporator coils, and is then ducted forward to the distribution
manifold.

Airflow Selection
Serials 1602, 1821, 1840, 1863 thru 2437: The airflow selector
regulates the volume of airflow allowed into the cabin distribution
system through mechanical linkage to a butterfly valve in the
distribution manifold. If option installed, the blower fan is turned on
when the selector dial exceeds the full open position.
Serials 2438 and subs: The airflow selector on the system control
panel regulates the volume of airflow allowed into the cabin distribution
system. When the airflow selector is moved past the OFF position an
electro-mechanical linkage actuates a valve in the mixing chamber on
the forward firewall to the full open position. The air is then distributed
by either ram air or by an optional blower fan to the distribution
manifold mounted to the center, aft side of the firewall. The optional
blower fan system includes 0 (ram air), 1 (low fan), 2 (med fan), and 3
(high fan) airflow settings.
Vent Selection
Conditioned air from the distribution manifold can be proportioned and
directed to passengers and/or the windshield by manipulating the
cabin vent selector. The selector is mechanically linked to butterfly
valves at the entrances to the windshield diffuser and the cabin floor
ducting. There is continuous airflow to the panel and armrest eyeball
outlets. Each occupant can control the flow rate from 'off' to maximum
by rotating the nozzle.
When the selector is in the far left position, both butterfly valves are
closed providing maximum airflow to the panel and armrest eyeball
outlets.
Rotating the selector a quarter-turn clockwise opens the cabin floor
butterfly valve allowing airflow to the rear seat foot warmer diffusers
and the front seat outlets mounted to the underside of each kickplate.
Rotating the selector another quarter-turn clockwise opens the
windshield diffuser butterfly valve which permits shared airflow to the
defrosting mechanism and cabin floor outlets.
When the selector is in the far right position, the cabin floor butterfly
valve is closed providing maximum airflow to the windshield diffuser.

Pitot-Static System
The Pitot-Static system consists of a single heated Pitot tube mounted
on the left wing and dual static ports mounted in the fuselage. The
Pitot heat is pilot controlled through a panel-mounted switch. An
internally mounted alternate static pressure source provides backup
static pressure should that the primary static source becomes blocked.
Water traps with drains, under the floor in the cabin, are installed at
each Pitot and static line low point to collect any moisture that enters
the system. The traps should be drained at the annual inspection and
when water in the system is known or suspected.
Pitot Heat Switch
The heated Pitot system consists of a heating element in the pitot
tube, a rocker switch labeled PITOT HEAT, and associated wiring. The
switch and circuit breaker are located on the left side of the switch and
control panel. When the pitot heat switch is turned on, the element in
the Pitot tube is heated electrically to maintain proper operation in
possible icing conditions. Pitot heat should be used only when
required. The Pitot heat system operates on 28 VDC supplied through
the 7.5-amp PITOT HEAT/COOLING FAN circuit breaker on the NonEssential Bus.
Pitot Heat Light
Illumination of the amber PITOT HEAT caution light indicates that the
Pitot Heat switch is in the 'on' position and the Pitot heater is not
receiving electrical current. A current sensor on the Pitot heater power
supply wire provides current sensing. The PITOT HEAT warning light
operates on 28 VDC supplied through the 2-amp ANNUN / ENGINE

Alternate Static Source
An alternate static pressure source valve is installed on the switch and
control panel to the right of the pilot's leg. This valve supplies static
pressure from inside the cabin instead of the external static port. If
erroneous instrument readings are suspected due to water or ice in
the pressure line going to the standard external static pressure source,
the alternate static source valve should be turned on. Pressures within
the cabin will vary with open heater/vents. Whenever the alternate
static pressure source is selected, refer to Section 5 airspeed
calibration and altitude for corrections to be applied.
Stall Warning System
The airplane is equipped with an electro-pneumatic stall warning
system to provide audible warning of an approach to aerodynamic
stall. The system consists of an inlet in the leading edge of the right
wing, a pressure switch and associated plumbing, and a piezoceramic horn behind the instrument panel. As the airplane approaches
a stall, the low pressure on the upper surface of the wings moves
forward around the leading edge of the wings. As the low pressure
area passes over the stall warning sense inlet, a slight negative
pressure is sensed by the pressure switch. The pressure switch
completes a ground circuit causing the warning horn to sound, and
Serials 2044 and subsequent; the autopilot system to disconnect. The
warning horn provides a 94dB continuous 2800 Hz tone. The warning
sounds at approximately 5 knots above stall with full flaps and power
off in wings level flight and at slightly greater margins in turning and
accelerated flight. The system operates on 28 VDC supplied though
the 2-amp STALL WARNING circuit breaker on the Essential Bus.
With battery power on, the stall warning system preflight check is
accomplished as follows:
Stall warning system preflight check:
1. Use small suction cup and apply suction. A sound from the
warning horn will confirm that the system is operative.

Airplane Description
Cirrus Airplane Parachute System
The SR22 is equipped with a Cirrus Airplane Parachute System
(CAPS) designed to bring the aircraft and its occupants to the ground
in the event of a life-threatening emergency. The system is intended to
saves the lives of the occupants but will most likely destroy the aircraft
and may, in adverse circumstances, cause serious injury or death to
the occupants. Because of this it is important to carefully read the
CAPS descriptions in this section, section 3 Emergency Procedures
and Section 10, Safety and consider when and how you would use the
system.
• WARNING •
The parachute system does not require electrical power for
activation and can be activated at any time. The solidpropellant rocket flight path is upward from the parachute
cover. Stay clear of parachute canister area when aircraft is
occupied. Do not allow children in the aircraft unattended.
System Description
The CAPS consists of a parachute, a solid-propellant rocket to deploy
the parachute, a rocket activation handle, and a harness imbedded
within the fuselage structure.
A composite box containing the parachute and solid-propellant rocket
is mounted to the airplane structure immediately aft of the baggage
compartment bulkhead. The box is covered and protected from the
elements by a thin composite cover.
The parachute is enclosed within a deployment bag that stages the
deployment and inflation sequence. The deployment bag creates an
orderly deployment process by allowing the canopy to inflate only after
the rocket motor has pulled the parachute lines taut.
The parachute itself is a 2400-square-foot round canopy equipped with
a slider, an annular-shaped fabric panel with a diameter significantly
less than the open diameter of the canopy. The slider has grommets
spaced around its perimeter. The canopy suspension lines are routed
through these grommets so that the slider is free to move along the
suspension lines. Since the slider is positioned at the top of the
suspension lines near the canopy, at the beginning of the deployment

Section 7
Airplane Description

SR22
sequence the slider limits the initial diameter of the parachute and the
rate at which the parachute inflates. As the slider moves down the
suspension lines the canopy inflates.
A three-point harness connects the airplane fuselage structure to the
parachute. The aft harness strap is stowed in the parachute canister
and attached to the structure at the aft baggage compartment
bulkhead. The forward harness straps are routed from the canister to
firewall attach points just under the surface of the fuselage skin. When
the parachute deploys, the forward harness straps pull through the
fuselage skin covering from the canister to the forward attach points.
Activation Handle
CAPS is initiated by pulling the CAPS Activation T-handle installed in
the cabin ceiling on the airplane centerline just above the pilot’s right
shoulder. A placarded cover, held in place with hook and loop
fasteners, covers the T-handle and prevents tampering with the
control. The cover is be removed by pulling the black tab at the forward
edge of the cover.
Pulling the activation T-handle will activate the rocket and initiate the
CAPS deployment sequence. To activate the rocket, two separate
events must occur:
1. Pull the activation T-handle from its receptacle. Pulling the Thandle removes it from the o-ring seal that holds it in place and
takes out the slack in the cable (approximately two inches (5 cm)
of cable will be exposed). Once the slack is removed, the T-handle
motion will stop and greater force will be required to activate the
rocket.
2. Clasp both hands around activation T-handle and pull straight
downward with a strong, steady, and continuous force until the
rocket activates. A chin-up type pull works best. Up to 45.0 pounds
(20.4 Kg) force, or greater, may be required to activate the rocket.
The greater force required occurs as the cable arms and then
releases the rocket igniter firing pin. When the firing pin releases,
two primers discharge and ignite the rocket fuel.

Airplane Description
• Note •
Jerking or rapidly pulling on the activation T-handle greatly
increases the pull forces required to activate the rocket.
Attempting to activate the rocket by pushing the activation Thandle forward and down limits the force that can be applied.
Pulling the activation T-handle straight down generates the
greatest force.
A maintenance safety pin is provided to ensure that the activation
handle is not pulled during maintenance. However, there may be some
circumstances where an operator may wish to safety the CAPS
system; for example, the presence of unattended children in the
airplane, the presence of people who are not familiar with the CAPS
activation system in the airplane, or during display of the airplane.
The pin is inserted through the handle retainer and barrel locking the
handle in the “safe” position. A “Remove Before Flight” streamer is
attached to the pin.
• WARNING •
After maintenance has been performed or any other time the
system has been safetied, operators must verify that the pin
has been removed before further flight.
Deployment Characteristics
When the rocket launches, the parachute assembly is extracted
outward due to rocket thrust and rearward due to relative wind. In
approximately two seconds the parachute will begin to inflate.
When air begins to fill the canopy, forward motion of the airplane will
dramatically be slowed. This deceleration increases with airspeed but
in all cases within the parachute envelope should be less than 3 g’s.
During this deceleration a slight nose-up may be experienced,
particularly at high speed; however, the rear riser is intentionally
snubbed short to preclude excessive nose-up pitch. Following any
nose-up pitching, the nose will gradually drop until the aircraft is
hanging nose-low beneath the canopy.
Eight seconds after deployment, the rear riser snub line will be cut and
the aircraft tail will drop down into its final approximately level attitude.
Once stabilized in this attitude, the aircraft may yaw slowly back and

forth or oscillate slightly as it hangs from the parachute. Descent rate
is expected to be less than 1700 feet per minute with a lateral speed
equal to the velocity of the surface wind. In addition, surface winds
may continue to drag the aircraft after ground impact.
• Caution •
Ground impact is expected to be equivalent to touchdown
from a height of approximately 13 feet. While the airframe,
seats and landing gear are designed to accommodate this
stress, occupants must prepare for it in accordance with the
CAPS Deployment procedure in Section 3 - Emergency
Procedures.
• Note •
The CAPS is designed to work in a variety of aircraft attitudes,
including spins. However, deployment in an attitude other than
level flight may yield deployment characteristics other than
those described above.

Airworthiness Directives
The Federal Aviation Administration (FAA) publishes Airworthiness
Directives (AD’s) that apply to specific aircraft and aircraft appliances
or accessories. AD’s are mandatory changes and must be complied
with within a time limit set forth in the AD. Operators should
periodically check with Cirrus Service Centers or A&P mechanic to
verify receipt of the latest issued AD for their airplane.
Airplane Inspection Periods
• Note •
FAR 1.1 defines time in service, with respect to maintenance
time records, as “the time from the moment an aircraft leaves
the surface of the earth until it touches it at the next point of
landing.”
Serials 1821, 1840, 1863 and subsequent: The #2 Hour
Meter, located in the center console and labeled FLIGHT,
begins recording when the airplane reaches approximately 35
KIAS and should be used to track maintenance time intervals
as it more accurately records time in service than the #1 Hour
Meter which begins recording when the BAT 1 switch is ON
and either the ALT 1 or ALT 2 switch is ON.
The inspection items specified in the Annual/100 Inspection
have been determined by the average aircraft use rate of the
typical owner. Non-commercially operated aircraft that are
flown significantly more than 100 hours per year should
consider additional inspections commensurate with the hours
flown. 100-Hour Inspection or enrollment in a Progressive
Inspection Program should be considered in addition to the
normally required Annual Inspection. The Annual Inspection
interval may also be shortened to accommodate high
utilization rate.
Annual Inspection
Unless enrolled in a Progressive Inspection Program, The U.S.
Federal Aviation Regulations require all civil aircraft must undergo a
thorough Annual Inspection each twelve calendar months. Annual
Inspections are due on the last day of the twelfth month following the
8-6
P/N 20880-001 Info Manual
September 2011
Cirrus Design
SR22
Section 8
Handling, Servicing, Maintenance
last Annual Inspection. For example: If an Annual Inspection were
performed on 19 November 1998, the next Annual Inspection will be
due 30 November 1999. Annual Inspections must be accomplished
regardless of the number of hours flown the previous year and can
only be performed by a licensed Airframe and Powerplant (A&P)
mechanic holding an Inspection Authorization (IA). All Cirrus
Authorized Service Centers can perform Annual Inspections. The
inspection is listed, in detail, in Chapter 5 of the Aircraft Maintenance
Manual.
100-Hour Inspection
If the airplane is used commercially, in addition to the Annual
Inspection requirement, the Federal Aviation Regulations requires that
the airplane undergo a 100-Hour Inspection each 100 hours of flight
operation. The scope of the 100-Hour Inspection is identical to the
Annual Inspection except that it can be accomplished by a licensed
A&P mechanic. The 100-hour interval may be exceeded by not more
than 10 flight hours in order to reach a place where the inspection can
be accomplished. Any flight hours used to reach an inspection station
must be deducted from the next 100-Hour Inspection interval. The
inspection is listed, in detail, in Chapter 5 of the Aircraft Maintenance
Manual.
Cirrus Design Progressive Inspection Program
In lieu of the above requirements, an airplane may be inspected using
a Progressive Inspection Program in accordance with the Federal
Aviation Regulation Part 91.409.
The Cirrus Design Progressive Inspection Program provides for the
complete inspection of the airplane utilizing a five-phase cyclic
inspection program. A total of eight inspections are accomplished over
the course of 400 flight hours, with an inspection occurring every 50
flight hours. The inspection items to be covered in the Progressive
Inspection are very similar to the Annual Inspection items. The
Progressive Inspection will accomplish a full Inspection of the airplane
at 400 flight hours or at 12 calendar months. The inspection is listed, in
detail, in Chapter 5 of the Aircraft Maintenance Manual.

Ground Handling
Application of External Power
A ground service receptacle, located just aft of the cowl on the left side
of the airplane, permits the use of an external power source for cold
weather starting and maintenance procedures.
• WARNING •
If external power will be used to start engine, keep yourself,
others, and power unit cables well clear of the propeller
rotation plane.
To apply external power to the airplane:
• Caution •
Do not use external power to start the airplane with a ‘dead’
battery or to charge a dead or weak battery in the airplane.
The battery must be removed from the airplane and battery
maintenance performed in accordance with the appropriate
Airplane Maintenance Manual procedures.
1. Ensure that external power source is regulated to 28 VDC.
2. Check BAT and AVIONICS power switches are ‘off.’
3. Plug external power source into the receptacle.
4. Set BAT 1 switch to ON. 28 VDC from the external power unit will
energize the main distribution and essential distribution buses.
The airplane may now be started or electrical equipment
operated.
5. If avionics are required, set AVIONICS power switch ON.
• Caution •
If maintenance on avionics systems is to be performed, it is
recommended that external power be used. Do not start or
crank the engine with the AVIONICS power switch ‘on.’
To remove external power from airplane:
1. If battery power is no longer required, set BAT 1 switch ‘off.’
2. Pull external power source plug.

The airplane may be moved on the ground by the use of the nose
wheel steering bar that is stowed in the rear baggage compartment or
by power equipment that will not damage or excessively strain the
nose gear assembly. The steering bar is engaged by inserting it into
lugs just forward of the nose wheel axle.
• Caution •
While pushing the aircraft backward, the tow bar must be
installed to keep the nose wheel from turning abruptly.
Do not use the vertical or horizontal control surfaces or
stabilizers to move the airplane. If a tow bar is not available,
use the wing roots as push points.
Do not push or pull on control surfaces or propeller to
maneuver the airplane.
Do not tow the airplane when the main gear is obstructed with
mud or snow.
If the airplane is to be towed by vehicle, do not turn the nose
wheel more than 90 degrees either side of center or structural
damage to the nose gear could result.
1. Refer to Airplane Three View (Section 1, Figure 1-1) and Turning
Radius (Section 1, Figure 1-2) or clearances. Be especially
cognizant of hangar door clearances.
2. Insert tow bar into the lugs just forward of the nose wheel axle.

Landing Gear Servicing
The main landing gear wheel assemblies use 15 x 6.00 x 6, six-ply
rating tires and tubes. The nose wheel assembly uses a 5.00 x 5 fourply rating, type III tire and tube. Always keep tires inflated to the rated
pressure to obtain optimum performance and maximum service. The
landing gear struts do not require servicing. With the exception of
replenishing brake fluid, wheel and brake servicing must be
accomplished in accordance with Airplane Maintenance Manual
procedures.
Brake Servicing
Brake Replenishing
The brake system is filled with MIL-H-5606 hydraulic brake fluid. The
fluid level should be checked at every oil change and at the annual/
100-hour inspection, replenishing the system when necessary. The
brake reservoir is located on the right side of the battery support
frame. If the entire system must be refilled, refer to the Airplane
Maintenance Manual.
To replenish brake fluid:
1. Chock tires and release parking brake.
2. Remove top engine cowling to gain access to hydraulic fluid
reservoir.
3. Clean reservoir cap and area around cap before opening reservoir
cap.
4. Remove cap and add MIL-H-5606 hydraulic fluid as necessary to

Brake Inspection
The brake assemblies and linings should be checked at every oil
change (50 hours) for general condition, evidence of overheating, and
deterioration. Serials 0002 thru 3450 before SB 2X-05-01: At every
annual/100-hour inspection the brakes should be disassembled, the
brake linings should be checked and the O-rings replaced.
The aircraft should not be operated with overheated, damaged, or
leaking brakes. Conditions include, but are not limited to:
• Leaking brake fluid at the caliper. This can be observed by
checking for evidence of fluid on the ground or deposited on the
underside of the wheel fairing. Wipe the underside of the fairing
with a clean, white cloth and inspect for red colored fluid
residue.
• Overheated components, indicated by discoloration or warping
of the disk rotor. Excessive heat can cause the caliper
components to discolor or cause yellowing of the part
identification label.
To inspect the brake assemblies:
1. Remove main gear fairing. (Refer to AMM 32-10)
2. Wipe off any debris from brake caliper assembly that may obstruct
inspection.
3. Check brake linings for deterioration and maximum permissible
wear. Replace lining when worn to 0.100 inch (2.54 mm).
4. Inspect temperature indicator(s):
a. Clean and inspect temperature indicators installed to brake
caliper assembly.
b.
Verify temperature indicators are firmly adhered to piston
housing.
c.
If either temperature indicator is black, the brake assembly
has overheated. The brake linings must be inspected and the
O-rings replaced.
5. Check brake assemblies for evidence of overheating and/or
deterioration.
6. Install main gear fairing. (Refer to AMM 32-10)

Tire Inflation
For maximum service from the tires, keep them inflated to the proper
pressure. When checking tire pressure, examine the tires for wear,
cuts, nicks, bruises and excessive wear.
To inflate tires:
1. Remove inspection buttons on wheel pants to gain access to
valve stems. It may be necessary to move airplane to get valve
stem aligned with the access hole.
2. Remove valve stem cap and verify tire pressure with a dial-type
tire pressure gage.
3. Inflate nose tire to 40 psi (275 kPa) and main wheel tires to 62 psi
(427 kPa).
4. Replace valve stem cap and inspection buttons.
All wheels and tires are balanced before original installation and the
relationship of tire, tube, and wheel should be maintained upon
reinstallation. In the installation of new components, it may be
necessary to rebalance the wheels with the tires mounted.
Unbalanced wheels can cause extreme vibration in the landing gear.
Propeller Servicing
The spinner and backing plate should be cleaned and inspected for
cracks frequently. Before each flight the propeller should be inspected
for nicks, scratches, and corrosion. If found, they should be repaired as
soon as possible by a rated mechanic, since a nick or scratch causes
an area of increased stress which can lead to serious cracks or the
loss of a propeller tip. The back face of the blades should be painted
when necessary with flat black paint to retard glare. To prevent
corrosion, the surface should be cleaned and waxed periodically.

Fuel Requirements
Aviation grade 100 LL (blue) or 100 (green) fuel is the minimum octane
approved for use in this airplane.
• Caution •
Use of lower grades can cause serious engine damage in a
short period. The engine warranty is invalidated by the use of
lower octane fuels.
Filling Fuel Tanks
Observe all safety precautions required when handling gasoline. Fuel
fillers are located on the forward slope of the wing. Each wing holds a
maximum of 40.5 U.S. gallons. When using less than the standard
81.0 U.S. gallon capacity, fuel should be distributed equally between
each side.
• WARNING •
Have a fire extinguisher available.
Ground fuel nozzle and fuel truck to airplane exhaust pipe and
ground fuel truck or cart to suitable earth ground.

a suitable earth ground.
3. Place rubber protective cover over wing around fuel filler.
• Note •
Do not permit fuel nozzle to come in contact with bottom of
fuel tanks. Keep fuel tanks at least half full at all times to
minimize condensation and moisture accumulation in tanks. In
extremely humid areas, the fuel supply should be checked
frequently and drained of condensation to prevent possible
distribution problems.
4. Remove fuel filler cap and fuel airplane to desired level.
• Note •
If fuel is going to be added to only one tank, the tank being
serviced should be filled to the same level as the opposite
tank. This will aid in keeping fuel loads balanced.
5. Remove nozzle, install filler cap, and remove protective cover.
6. Repeat refuel procedure for opposite wing.
7. Remove ground wires.
8. Remove fire extinguisher.

Fuel Contamination and Sampling
Typically, fuel contamination results from foreign material such as
water, dirt, rust, and fungal or bacterial growth. Additionally, chemicals
and additives that are incompatible with fuel or fuel system
components are also a source of fuel contamination. To assure that
the proper grade of fuel is used and that contamination is not present,
the fuel must be sampled prior to each flight.
Each fuel system drain must be sampled by draining a cupful of fuel
into a clear sample cup. Fuel drains are provided for the fuel
gascolator, wing tanks, and collector tank drains. The gascolator drain
exits the lower engine cowl just forward of the firewall near the airplane
centerline. Fuel tank and collector tank drains are located at the low
spot in the respective tank.
If sampling reveals contamination, the gascolator and tank drains must
be sampled again repeatedly until all contamination is removed. It is
helpful to gently rock the wings and lower the tail slightly to move
contaminates to the drain points for sampling. If after repeated
samplings (three or more), evidence of significant contamination
remains, do not fly the airplane until a mechanic is consulted, the fuel
system is drained and purged, and the source of contamination is
determined and corrected.
Airplane serials 2710 thru 3420 before SB 2X-28-08 R1; The
gascolator incorporates a filter bypass that activates a red, pop-up tab
when pressure drop across the gascolator reaches 0.8 ± 0.2 PSI. The
filter is bypassed when the pressure drop reaches 1.20 ± 0.2 PSI.
Once the pop-up tab is activated, the fuel filter element must be
replaced and the pop-up tab manually reset. Do not attempt to clean
the filter element.
If sampling reveals the airplane has been serviced with an improper
fuel grade, do not fly the airplane until the fuel system is drained and
refueled with an approved fuel grade.
To help reduce the occurrence of contaminated fuel coming from the
supplier or fixed based operator, pilots should assure that the fuel
supply has been checked for contamination and that the fuel is
properly filtered. Also, between flights, the fuel tanks should be kept as
full as operational conditions permit to reduce condensation on the
inside of fuel tanks.

Draining Fuel System
The bulk of the fuel may be drained from the wing fuel tanks by the use
of a siphon hose placed in the cell or tank through the filler neck. The
remainder of the fuel may be drained by opening the drain valves. Use
the same precautions as when refueling airplane. Refer to the SR22
Maintenance Manual for specific procedures.
Battery Service
Battery #1 is mounted to the forward right side of the firewall and
access is gained by removing the upper cowl. The battery vent is
connected to an acid resistant plastic tube that vents gases and
electrolyte overflow overboard. Battery #2 is located behind the
baggage compartment aft bulkhead below the parachute canister.
Battery #2 consists of two sealed, maintenance-free units and is not
considered pilot serviceable.
Battery #1 fluid level must not be brought above the baffle plates. Until
experience indicates a longer interval is justified, the battery should be
checked every 30 days or 25 flight hours to determine that the fluid
level is proper and the connections are tight and free of corrosion. Do
not fill the battery with acid use distilled water only. If the battery is not
properly charged, recharge it starting with a rate of four amperes and
finishing with a rate of two amperes in accordance with Airplane
Maintenance Manual procedures. The battery should be removed
from the airplane for charging, and quick charges are not
recommended.
Battery 2 is a maintenance free, rechargeable, sealed, lead acid
batter. Mounted in the empennage just aft of bulkhead 222, there is no
need to check the specific gravity of the electrolyte or add water to
these batteries during their service life. Refer to the Airplane
Maintenance Manual for Overhaul and Replacement Schedule.
The external power receptacle is located on the left side of the
fuselage just aft of the firewall. Refer to the Airplane Maintenance
Manual for battery servicing procedures.

abrasives or alkaline soaps or detergents could make scratches on
painted or plastic surfaces or could cause corrosion of metal. Cover
static ports and other areas where cleaning solution could cause
damage. Be sure to remove the static port covers before flight. To
wash the airplane, use the following procedure:
1. Flush away loose dirt with water.
2. Apply cleaning solution with a soft cloth, a sponge or a soft bristle
brush.
3. To remove exhaust stains, allow the solution to remain on the
surface longer.
4. To remove stubborn oil and grease, use a cloth dampened with
naphtha.
5. Rinse all surfaces thoroughly.
Any good silicone free automotive wax may be used to preserve
painted surfaces. Soft cleaning cloths or a chamois should be used to
prevent scratches when cleaning or polishing. A heavier coating of
wax on the leading surfaces will reduce the abrasion problems in these
areas.

A fail-safe circuit connects the pilot’s headset directly to the COM1
transceiver in the event of a power failure to the audio control panel or
the panel is switched ‘OFF.’
Test
Pressing the TEST button illuminates all Panel LEDs and the Marker
Beacon Annunciators full bright. During normal operation, a photocell
mounted at the approximate center of the control panel senses
ambient light to allow automatic LED and annunciator intensity
adjustment. Nomenclature dimming is controlled by the INST lights
control on the instrument panel bolster.
Audio/Transceiver Selection
Audio selection is performed through the eight selector push buttons in
the center of the Audio Control Panel. All audio selector push buttons
are push-on, push-off. Selecting an audio source supplies audio to the
headphones or cabin speaker. Selected audio sources are indicated
by illumination of the push-button switch.
Navigation receiver audio source is selected by depressing NAV1,
NAV2 (if installed), MKR, DME (if installed), or ADF (if installed) will
select that radio or device as the audio source. Audio level of
navigation receivers is controlled through the selected radio volume
control.
Transceiver audio is selected by depressing COM1, COM2, or COM3
(if installed). When the audio source is selected using the COM1,
COM2, and COM3 buttons, the audio source will remain active
regardless of which transceiver is selected as the active MIC source.
Both transceiver audio and MIC (microphone) can be selected by
depressing COM1 MIC, COM2 MIC, or COM3 MIC (if installed). Both
pilot and copilot are connected to the selected transceiver and both
have transmit and receive capabilities. Pilot and copilot must use their
respective Push-To-Talk (PTT) switch to transmit. The intercom will
function normally. During transmissions the active transmitter’s COM
MIC button LED blinks at a 1 Hz rate indicating active transmission.
Split COM Function
Pressing the COM 1/2 button activates the split COM function. When
split COM is active, COM 1 is the pilot mic/audio source and COM2 is

the copilot mic/audio source. The pilot has receive and transmit
capabilities on COM1 and the copilot has receive and transmit
capabilities on COM2. While split COM is active, simultaneous
transmission from COM1 and COM2 is not possible.The pilot and
copilot can still listen to COM3, NAV1, NAV2, DME, ADF, and MKR.
Pressing the COM 1/2 button a second time will deactivate the split
COM function. While split COM is active, the copilot is able to make PA
announcements over the cabin speaker allowing the pilot to continue
using COM1 independently. This is accomplished by depressing the
PA button while split COM is active. Pressing the PA button a second
time deactivates this feature and returns the system to normal split
COM as described above.
COM Swap Mode
COM swap mode is not available in this installation.
Speaker Output
Pressing the SPKR button will cause the selected airplane radios to be
heard over the cabin speaker. Speaker output is muted when a COM
microphone is keyed. Speaker level is adjustable through an access
hole in the top of the unit (refer to Garmin installation manual or AMM).
Public Address (PA) Function
Pressing the PA button on the audio control panel activates the PA
function. When PA is activated and either the pilot’s or copilot’s
microphone is keyed (PTT pressed), the corresponding mic audio is
output over the cabin speaker. If the SPKR button is also active, any
previously active speaker audio will be muted while the microphone is
keyed. Pilot and copilot PA microphone speaker levels are adjustable
through an access hole in the top of the unit (refer to Garmin
installation manual or AMM).

The Audio Control Panel has provisions for up to two separate
personal entertainment input (music) devices. These devices are
plugged into the AUDIO INPUT jacks in the center console jack
panels. Music1 is connected at the AUDIO INPUT jack near the
convenience outlet. Music2 is connected to the jack on the aft console.
Music1 is soft-muted during all airplane radio activity. Music1 and
Music2 have characteristics affected by the active ICS isolation mode.
• Pressing the PILOT ICS Isolation button isolates the pilot from
the copilot and passengers. Music1 is available to copilot and
passengers.
• Pressing the CREW ICS Isolation button isolates the crew from
the passengers and allows the pilot and copilot to listen to
Music1 and the passengers to listen to Music2. Radio activity,
MKR activity, and pilot or copilot ICS activity will mute Music1.
Music2 is not muted.
• When both the PILOT and CREW ICS Isolation mode are not
selected, Music1 is available to crew and passengers. Radio
activity and MKR activity will mute Music1.
Intercom
Intercom controls are located towards the left side of the Audio Control
Panel. The controls consist of a Volume control for the pilot and
copilot, a Squelch control for all occupants, and an Intercom Mode
Selector switch.
Volume & Squelch Control
ICS volume and voice operated relay (VOX) squelch control is
controlled through the left (PILOT) and right (COPILOT) control knobs
on the Audio Control Panel Control. Knob control is as follows:
• Left Inner Knob – On/Off power control and pilot ICS volume.
Full CCW is ‘OFF’ position (click).
• Left Outer Knob – Pilot ICS mic VOX level. CW rotation
increases the amount of mic audio (VOX level) required to
break squelch. Full CCW is the ‘hot mic’ position.
• Right Inner Knob – When pushed in, rotation controls copilot
ICS volume. When out, rotation controls passenger ICS
volume.

• Right Outer Knob – Copilot and passenger mic VOX level. CW
rotation increases the amount of mic audio (VOX level) required
to break squelch. Full CCW is the ‘hot mic’ position.
Each microphone input has a dedicated VOX circuit to assure that only
the active microphone(s) is/are heard when squelch is broken. After
the operator has stopped talking, the intercom channel remains
momentarily open to avoid closure between words or normal pauses.
Control
The Audio Control Panel provides an adjustable Voice Operated Relay
(VOX) Squelch Control for the pilot, copilot, and passengers. Since the
VOX circuits reduce the number of microphones active at any one
time, the amount of unwanted background noise in the headphones is
diminished. This also allows the use of dissimilar headsets with the
same intercom. Because the user can adjust the trip level of the VOX
squelch to fit the individual voice and microphone, this helps eliminate
the frustration of clipping the first syllables. There is a slight delay after
a person stops talking before the channel closes. This prevents
closure between words and eliminates choppy communications.
To adjust squelch:
1. With the engine running, set the VOX trip level by slowly rotating
the SQL control knob clockwise until you no longer hear the
engine noise in the headphones.
2. Position microphone near your lips and speak into microphone.
Verify that normal speech levels open the channel.
Intercom Modes
The GMA 340 provides three intercom (ICS) modes to further simplify
workload and minimize distractions during all phases of flight: PILOT,
CREW, and ALL. The mode selection is accomplished using the
PILOT and CREW push-buttons. Pressing a button activates the
corresponding ICS mode and pressing the button a second time
deactivates the mode. The operator can switch modes (PILOT to
CREW or CREW to PILOT) by pressing the desired modes push-

button. ALL mode is active when neither PILOT or CREW have been
selected.
PILOT
The pilot is isolated from the intercom. The pilot can hear
radio and sidetone only during radio transmissions. Copilot
and passengers can hear the intercom and music but not the
airplane radio receptions or pilot transmissions.
CREW
Pilot and copilot are connected on one intercom channel and
have exclusive access to the aircraft radios. They may also
listen to Music1. Passengers can continue to communicate
with themselves without interrupting the Crew and also may
listen to Music2.
ALL
All parties will hear the aircraft radio, intercom, and Music1.
The music volume increases gradually back to the original
level after communications have been completed. Both pilot
and copilot have access to the COM transceivers.

GARMIN GTX 327 Mode A/C Transponder Pilots Guide, p/n
190-00187-00 September 2011 (Feb 2000) or later revision.
The Garmin GTX 327 transponder system consists of the integrated
receiver/transmitter control unit, an antenna, and an altitude digitizer.
The receiver/transmitter receives interrogations from a ground-based
secondary surveillance radar transmitter and then transmits to the
interrogating Air Traffic Control Center. Digitized altitude information is
provided by the altitude digitizer (encoder) plumbed into the airplane
static system. The transponder and integrated controls are mounted in
the center console. The transponder control provides active code
display, code selection, IDENT button, and test functions. The display
is daylight readable and is automatically dimmed through a photocell.
The controller buttons are dimmed through the INST lights control on
the instrument panel bolster. The transponder antenna is mounted on
the underside of the fuselage just aft of the firewall. 28 VDC for
transponder operation is controlled through the Avionics Master
Switch on the bolster switch panel. 28 VDC for receiver, transmitter,
and altitude encoder operation is supplied through the 2-amp
ENCODER/XPONDER circuit breaker on the Avionics Non-Essential.

from ±1 (100 FPM) to ±16 (1600 FPM) is selectable.
• Note •
If an altitude is selected that requires an opposite vertical
speed from that selected, the system will automatically select
the correct sign (‘+’ for climb, ‘-‘for descent) and a vertical
speed of 500 FPM.
6. After takeoff, press and hold the VS button and then press the ALT
button to engage the autopilot VS mode and arm the autopilot
altitude hold mode to capture and hold the selected altitude. If the
altitude selector ALR button is pressed, the system will provide
alarms at 1000 feet and 300 feet from the selected altitude. As the
airplane’s altitude nears the selected altitude, the system

GPSS mode on the autopilot programmer/computer. When
the on-course intercept turn begins the HDG mode will
disengage and the annunciator will go out.
During the intercept sequence, the autopilot operates at
maximum gain and sensitivity (90% of standard rate turn).
When the selected course is intercepted, course deviation
needle centered, the course-tracking program is activated.
The system will remain at maximum sensitivity for
approximately 15 seconds while the wind correction angle is

Autopilot
The airplane is equipped with an S-Tec System 55X two-axis
Automatic Flight Control System (Autopilot). The autopilot
programmer/computer is installed in the center console radio stack.
The autopilot roll axis uses an inclined gyro in the turn coordinator
case as the primary turn and roll rate sensor. In addition to the turn
coordinator instrument, the roll axis computer receives signals from
the HSI and the #1 NAV/GPS radio. The roll computer computes roll
steering commands for turns, radio intercepts, and tracking. Roll axis
P/N 13772-108

SR22
steering is accomplished by autopilot steering commands to the
aileron trim motor and spring cartridge.
The pitch computer receives altitude data from the altitude encoder
pressure transducer plumbed into the static system, an accelerometer,
and glideslope information from the HSI and #1 NAV radio. Pitch axis
command for altitude hold, vertical speed hold, and glideslope tracking
is accomplished by pitch computer commands to the autopilot pitch
servo.
The altitude selector provides altitude and vertical speed pre-select
capability for the autopilot. A pre-programmed altitude and vertical
speed can be input into the altitude selector/alerter and then coupled
to the autopilot. The autopilot will then follow the selected vertical
speed until the selected altitude is reached. Then the altitude selector
will signal the autopilot to hold the selected altitude. The altitude
selector/alerter receives uncorrected altitude data from the same
altitude encoder used by the transponder. In addition to the preselect
functions, the altitude selector provides altitude alert, decision height,
and altitude readout.
28 VDC for autopilot and altitude selector/alerter is supplied through
the 5-amp AUTOPILOT circuit breaker on the Essential Bus.
All Autopilot mode selection is performed by using the mode select
buttons and VS knob on the autopilot programmer/computer in the
center console. Annunciators in the programmer/computer display
window annunciate modes. Refer to Figure 1 for an illustration of the
programmer/computer.
RDY (Ready)– Illuminates when autopilot is ready for engagement.
When the airplane’s Battery Master switch is turned on and the rate
gyro RPM is correct, the RDY annunciator will come on indicating the
autopilot is ready for the functional check and operation. The autopilot
cannot be engaged unless the RDY light is illuminated.

HDG (Heading) Mode – When HDG is selected, the autopilot will
engage the HDG mode, fly the airplane to, and hold the heading set on
the HSI. Subsequent heading changes are made using the HDG knob
on the HSI. For smoothest transition to HDG mode, it is recommended
that the airplane be aligned to within 10° of the selected heading
before engaging HDG. The HDG mode is also used in combination
with the NAV mode to set up a pilot selected intercept angle to a
course.
GPSS (GPS Steering) – Pressing NAV twice will cause the autopilot
to go to GPSS for smoother tracking and transitions. When GPSS is
selected, the autopilot can be switched between heading and GPSS
modes of operation. In the heading mode, the converter receives a
heading error signal from the heading bug on the Horizontal Situation
Indicator. GPSS converts this information and sends this heading error
directly to the autopilot.
In the GPSS mode, the converter receives ground speed and bank
angle digital signals that are calculated and converted to a
commanded turn rate. The turn rate is then scaled and converted to a
DC heading error signal that is compatible with the autopilot. The end
result is an autopilot that can be directly coupled to the roll steering
commands produced by the GPS Navigator, eliminating the need for
the pilot to make any further adjustments to the HSI course arrow.
REV (Reverse Course) – When REV is selected, the autopilot will
automatically execute high sensitivity gain for an approach where
tracking the front course outbound or tracking the back course inbound
is required. The APR and REV annunciators will illuminate when REV
is selected.
APR (Approach) – When APR is selected, the autopilot provides
increased sensitivity for VOR or GPS approaches. APR may also be
used to provide increased sensitivity for enroute course tracking.

GS (Glideslope) – The autopilot GS function will capture and track an
ILS glideslope. To arm the GS function, the following conditions must
be met: (1) the NAV receiver must be tuned to the appropriate ILS
frequency; (2) The glideslope signal must be valid – no flag; (3) the
autopilot must be in NAV/APR/ALT modes; and (4) the airplane must
be 60% or more below the glideslope centerline during the approach
to the intercept point, and within 50% needle deviation of the localizer
centerline at the point of intercept – usually the outer marker. When
the above conditions have existed for 10 seconds, the GS annunciator
will illuminate indicating GS arming has occurred (ALT annunciator will
remain on). When the glideslope is intercepted and captured, the ALT
annunciator will go out.
ALT (Altitude Hold), Mode – When ALT is selected, the autopilot will
hold the altitude at the time the mode was selected. Altitude hold will
not engage if an autopilot roll mode is not engaged. Altitude correction
for enroute barometric pressure changes may be made by rotation of
the VS knob on the autopilot programmer/computer. Clockwise
rotation will increase and counterclockwise rotation will decrease
altitude 20 feet for each ‘click.’ The maximum adjustment is ±360 feet.
Adjustments greater than 360 feet can be made by selecting VS mode
and flying the airplane to the new altitude and then re-engaging ALT
mode.
VS (Vertical Speed) Mode – When VS is selected, the autopilot will
synchronize to and hold the vertical speed at the time the mode was
selected. Altitude hold will not engage if an autopilot roll mode is not
engaged. The vertical speed is displayed in 100-foot increments at the
far right of the programmer/computer window next to the VS
annunciation. A plus (+) value indicates climb and a negative or minus
(-) value indicates descent. Vertical speed can be adjusted by rotating
the VS knob on the programmer/computer. Clockwise rotation
increases and counterclockwise rotation decreases rate of climb (or
descent) 100 FPM for each ‘click.’ The maximum adjustment is ±1600
FPM.

Altitude Selector / Alerter
The altitude selector / alerter provides the autopilot with an altitude
preselect function, a programmable vertical speed function, as well as
provides altitude alert, decision height alert, and baro corrected
altitude display. The altitude selector reads and decodes altitude
information from the same altitude encoder that provides altitude
information to the transponder. The decoded altitude is baro corrected
and then compared to the selected altitude setting. When the decoded
and baro corrected altitude matches the selected altitude, the altitude
selector signals the autopilot to engage the ALT hold mode. The
altitude select (ALT SEL) function is operable only when the
transponder and encoder are operating and then both the autopilot
ALT and VS modes are selected.
The altitude selector also provides a vertical speed signal to the
autopilot pitch computer that is proportional to the amplitude and
direction of the selected or computed vertical speed. This signal is not
used by the autopilot until the autopilot VS mode is engaged. When
VS is engaged, the autopilot compares the selected vertical speed
signal with the existing vertical speed derived from the autopilot’s
altitude transducer and maneuvers the airplane to attain the selected
vertical speed. The Vertical Speed (VS) select portion of the altitude
selector / alerter is showing a selected vertical speed (VS annunciator
on) and the autopilot Vertical speed (VS) mode is engaged.
The altitude selector / alerter also provides Decision Height (DH) and
Altitude Alert (ALR) selection. All selector function selection is made
through the altitude selector/alerter. Available functions are as follows:

DTA (Data) – The data entry button is used to select data entry mode.
The first time the DTA button is pressed the selector will enter the data
entry mode, the ENT annunciator will come on, and the SEL
annunciator will flash to indicate the system is ready to accept an
altitude entry. To change baro (BAR) correction, Decision Height (DH),
or Vertical Speed (VS), press the appropriate button on the selector
and rotate the input knob at the right of the display CW to increase the
displayed numbers and CCW to decrease the displayed numbers. Pull
the knob out and rotate as required to change the decimal numbers.
When the system is in the ENT mode, it is not coupled to the autopilot.
In this mode, the autopilot will hold the last vertical speed selected.
• Note •
It is not necessary to enter the DTA mode to change the
vertical speed, if vertical speed is coupled to the autopilot. If
this is the case, vertical speed changes can be made by
rotating the input knob as required to obtain the new vertical
speed.
While in this mode, pressing DTA a second time will toggle the system
to ‘operate’ mode. Repeatedly pressing the DTA button will toggle the
system between ENT and ‘operate’ mode.
BAR (baro) – In this mode, the baro setting used by the altitude
selector may be changed. When the Altitude Selector / Alerter is
initially powered, the BARO mode is displayed automatically at the
completion of the self-test. At other times, it is necessary to enter the
data entry mode by pressing the DTA button and then inputting a new
baro correction. Pressing the DTA button a second time will return the
system to the ‘operate’ mode.

ALT (Altitude) – The ALT button has two functions: Altitude Pre-select
and Altitude readout.
Pre-select - When the ALT button is pressed while the system is in the
Data Entry (DTA) mode the SEL annunciator will flash and a new
altitude can be selected by rotating the input knob CW to increase
altitude and CCW to decrease altitude in thousands of feet. Pull the
knob to input altitude in hundreds of feet. For example: 5500 feet is
input as 5.5. Pressing DTA again will return the system to ‘operate’
mode and the SEL annunciator will stop flashing with the ALT
annunciator remaining on. When a preselect altitude is coupled to the
autopilot by pressing and holding the VS button and then pressing the
ALT button, the airplane will fly at the selected vertical speed until the
selected altitude is intercepted. At that time the altitude selector will
command the autopilot to engage altitude hold.
Readout – When the ALT button is pressed in the ‘operate’ mode, the
SEL annunciator will go out and the display will show the baro
corrected encoder altitude. Repeated pushes of the ALT button will
alternately display baro corrected encoder altitude and pre-selected
altitude.
ALR (Alert Mode) – The ALR button enables the altitude alert system
in conjunction with the ALT SEL mode. Pressing the ALR switch
illuminates the ALR annunciator indicating arming of the alert mode.
Upon entering within 1000 feet of the altitude selected in ALT SEL, the
altitude alert chime will sound in the cabin speaker and headphones
and the ALR annunciator will flash. The chime will sound and the ALR
annunciator will flash again as the airplane approaches within 300 feet
of the selected altitude. If the airplane’s altitude deviates ± 300 feet
from the selected altitude, the chime will sound and the ALR
annunciator will flash to indicate the condition. The ALR function can
be alternately enabled and disabled by repeatedly pressing the ALR
button.

DH (Decision Height) – The DH button allows entry and arming of
altitude alerting at a set decision height. To set a DH, first enter the
data (DTA) entry (ENT) mode, press the DH button, and rotate the
selector knob to input the desired decision height to the nearest 100
feet above the specified decision height. For example, for a DH of
1160 feet set 1.2 (1200 feet). After setting the desired decision height,
press the DTA button again to accept the entered DH. The display will
show the selected DH for approximately 5 seconds and then revert to
Alt mode until the selected DH is reached during descent. The DH
annunciator will remain illuminated indicating a decision height is set.
As the airplane approaches within approximately 50 feet of the
decision height, the alert will sound and the DH light will flash. As the
airplane passes through approximately 50 feet beyond the decision
height, the alert will sound and the light will flash again. Pressing the
DH button again will disable the DH function causing the DH
annunciation to go out. Repeated activation of the DH button
alternately activates and deactivates the DH mode.
VS (Vertical Speed) – At initial start up, after self-test, pressing the
Altitude Selector / Alerter VS button enables vertical speed selector
mode. The initial vertical speed will be set at + 2 indicating a climb at
200 feet per minute. Rotating the selector input knob will change the
selected vertical speed in 100 FPM increments. Rotate CW to
increase vertical speed or CCW to Decrease vertical speed. The
maximum vertical speed is ± 1600 FPM (± 16). Zero vertical speed is
not selectable.
The vertical speed display is the only Altitude Selector / Alerter
function available in the ‘operate’ mode. Therefore, vertical speed
changes can be commanded by rotating the selector input knob.
Vertical speeds can also be entered in the data (DTA) entry (ENT)
mode by pressing the VS button and using the selector input knob to
enter a new vertical speed. The DTA button must be pressed again to
accept the new vertical speed and enter the ‘operate’ mode.
The Altitude Selector / Alerter VS mode can be disabled by pressing
the Altitude Selector / Alerter MAN button.
MAN (Manual) – Vertical Speed selection can be completely
decoupled from the autopilot system by depressing the Altitude
Selector / Alerter MAN button.

Section 4 - Normal Procedures
• Caution •
Prolonged operation of the system in clear air, at very high
altitudes, and very cold temperatures can result in “flash”
evaporation of water and alcohol from the de-icing fluid. This
evaporation results in a glycol rich fluid that could become
“gel” like on the wing surface until the aircraft enters cloud or
descends to warmer temperatures.
• Note •
The Ice Protection System is approved for operation with ice
protection fluid that has a very temperature-dependant
viscosity characteristic. As the temperature of the fluid rises
above freezing (32F / 0C), the fluid becomes much less
viscous (thins) and pass through the porous membrane of the
panels with less resistance (pressure drop). This decrease in
pressure drop reduces the pressure in the panel reservoir
which may not be adequate to wet-out the entire panel if the
Pre-Flight Inspection is performed at warmer temperatures.

Section 5 - Performance
Cruise speed is lower by approximately three knots and range is
reduced by a maximum of 2%.
Experience with your airplane’s power settings may result in more
accurate performance numbers than those given above.
1. Reduce KTAS shown on the Cruise Performance tables and the
Range/Endurance Profile tables by 3 knots.
2. Reduce range shown on the Range/Endurance Profiles by 2%.
• Caution •
During certain flight conditions, such as at higher operating
altitudes and/or higher airspeeds, the stagnation point on the
leading edge of the wing (the point where the airflow splits) will
move up and aft enough to hinder the deicing fluid from
flowing adequately along the top surface of the wing. Airspeed
for optimum system performance is 95-139 KIAS. Do not
exceed 175 KTAS above 14000 ft.

Section 7 - System Description
The Ice Protection System can prevent, and in certain conditions,
remove ice accumulation on the flight surfaces by distributing a thin
film of glycol-based fluid on the wing, horizontal stabilizer, and
propeller. The presence of this fluid lowers the freezing temperature
on the flight surface below that of the ambient precipitation preventing
the formation and adhesion of ice.
Ice Protection System - Serials before G3 Wing
The system consists of six porous panels, propeller slinger ring, four
proportioning units, metering pump, filter, outlet strainer, fluid tank,
filler cap, electrical switching, and system plumbing. The system
operates on 28 VDC supplied through the 5-amp ICE PROTECTION
circuit breaker on Main Bus 1.
Storage and Distribution
The deicing fluid tank is serviced through a filler located on the LH side
of the fuselage, just forward of the baggage door. The fluid tank,
located behind the LH rear cabin trim panel, has a total capacity of
2.96 gallons (11.2L). A fine-mesh outlet strainer mounted internal to
the tank protects the metering pump from damage by contaminates.
Upon activation, a two-speed metering pump, mounted below the LH
passenger seat, draws fluid from the tank and provides fluid pressure
to the system at a constant-volume flow rate. Low pump speed
provides the required flow during NORMAL operation and high pump
speed during MAXIMUM operation. The manifold of the Metering
Pump is primed by actuating the gravity-fed Drain Valve located on the
lower fuselage skin.
From the metering pump, deicing fluid is pushed through a filter,
mounted adjacent to the pump, and then carried to the proportioning
units located in the wing, empennage, and cabin floor-forward through
nylon tubing.
• The LH and RH Wing proportioning units distributes fluid to the
Inboard and Outboard wing panels.
• The empennage proportioning unit distributes fluid to the LH
and RH horizontal panels.

• A cabin floor-forward proportioning unit distributes fluid to the
propeller slinger ring assembly.
In addition to distributing fluid to the porous panels and propeller
slinger ring, the proportioning units provide an additional, distinct
pressure drop to the supply lines such that a specific flow rate is
provided to each protected surface. Small, flap-type check valves
positioned on the outlet of each proportioning unit port prevent the
back-flow of fluid from the associated panel
Porous Panels
The proportioned fluid enters the leading edge panels through the inlet
fitting(s) on the inboard end of the wing panels, and outboard end of
the horizontal panels. The outer surface of the panels is perforated
with very small openings to distribute the deicing fluid along their
entire length. The panels contain a porous membrane whose pores
are nearly 100 times smaller than the openings of the outer surface.
The leading edge panel serves as a reservoir as fluid entering the
panel fills the cavity behind the porous membrane then overcomes this
resistance to be distributed by the openings in the external surface.
Each panel incorporates a vent opposite the inlet which provides a
relatively large opening to release air from within the panel. A check
valve prevents air from entering the panel through the vent which
slows the "leak-down" of the panel during periods of inactivity.
Propeller Slinger Ring
Deicing fluid protects the propeller by a slinger ring mounted to the
spinner backing plate where the fluid is distributed by centrifugal
action onto grooved rubber boots fitted to the root end of the propeller
blades.
System Control
System operation is controlled by, Serials 22-0334 thru 22-0434; a
three-position switch mounted on the center console panel which
allows the user to select OFF, NORMAL, or MAXIMUM positions.
Serials 22-0435 & subs; two switches located on the bolster panel.
The first switch controls system operation through ON and OFF
positions, the second switch controls the system mode (flow rate)
through NORMAL and HIGH positions.

Ice Protection System - Serials with G3 Wing
The system consists of six porous panels, propeller slinger ring, two
proportioning units, metering pump, priming pump, filter, in-line
strainer, fluid tank, filler cap and neck, test port assembly, electrical
switching, system plumbing, and (Serials w/ Perspective Avionics)
deicing fluid level sensor. The system operates on 28 VDC supplied
through 5-amp ICE PROTECTION circuit breaker on Main Bus 1.
Storage and Distribution
The 3.5 gallons (13.2L) deicing fluid tank is serviced through a filler
located on the upper LH wing skin. The tank is a sealed wet bay,
integral to the wing structure, bounded by the upper and lower wing
skins, main spar web, and the inboard, outboard, and lateral tank ribs.
The tank is vented from the outboard rib to a NACA style duct attached
to an access panel on the lower wing skin, just outboard of the tank. A
course-mesh outlet strainer mounted internal to the tank prevents
large objects from obstructing the tank outlet, while a fine-mesh in-line
strainer protects the metering pump and primping pump from damage
by contaminates.
Upon activation, a two-speed metering pump, mounted below the LH
passenger seat, draws fluid from the tank and provides fluid pressure
to the system at a constant-volume flow rate. Low pump speed
provides the required flow during NORMAL operation and high pump
speed during HIGH/MAXIMUM operation. The manifold of the
metering pump is primed by an integral priming pump which draws
fluid through the manifold and returns it to the tank. A check valve
between the priming pump and the tank prevents back-flow of fluid to
the metering pump. The priming pump operates for the first 10
seconds of system operation. In the event of the loss of prime, the
priming pump can be activated to draw fluid from the tank to prime the
metering pump manifold.
From the metering pump, deicing fluid is pushed through a filter,
mounted adjacent to the pump, and then carried through nylon tubing
to the proportioning units located in the cabin floor-forward and
empennage.
• The cabin floor-forward proportioning unit distributes fluid to the

The inlet fitting of the Inboard wing porous panel also supplies fluid to
the porous stall strip through an additional capillary tube which further
proportions the fluid to provide a specific flow rate to the stall strip.
Each panel incorporates a vent opposite the inlet which provides a
relatively large opening to release air from within the panel. A check
valve prevents air from entering the panel through the vent which
slows the "leak-down" of the panel during periods of inactivity.
Propeller Slinger Ring
Deicing fluid protects the propeller by a slinger ring mounted to the
spinner backing plate where the fluid is distributed by centrifugal
action onto grooved rubber boots fitted to the root end of the propeller
blades.
System Control
System operation is controlled by two switches located on the bolster
panel. The first switch controls system operation through ON and OFF
positions, the second switch controls the system mode (flow rate)
through NORMAL and HIGH positions.

• Caution •
During long periods of non-use, the porous panel membranes
may dry out which could cause uneven fluid flow during
subsequent operation. Perform the Pre-Flight Inspection every
30 days to keep porous panel membranes wetted.
Use only approved deicing fluid. See Section 2, Limitations. To
prevent fluid contamination, maintain a clean, dedicated
measuring container and ensure mouth of fluid container is
clean before dispensing. Secure the filler cap immediately
after filling
Certain solvents may damage the panel membrane. Use only
soap and water, isopropyl alcohol, or ethyl alcohol to clean
panels. Do not wax leading edge porous panels.
Storage
To prepare the Ice Protection System for flyable storage, fill the deicing
fluid tanks and perform the Pre-Flight Inspection to verify evidence of
ice protection fluid along the length of all porous panels. The tanks
may then be drained until the next service interval (30 days minimum)
or operation of the system is desired.
Servicing
De-Icing Fluid Tank
Serials before G3 Wing: The ice protection fluid tank is serviced
through a filler cap located on the LH side of the fuselage, just forward
of the baggage door. The tank is drained by actuating the Drain Valve
on the lower LH side of fuselage skin, just forward of fluid tank.
Serials w/ G3 Wing: The ice protection fluid tank is serviced through a
filler cap located on the upper LH wing skin. The tank is drained by a
lock-open/lock-close drain valve, located on an access panel in the
lower LH wing skin.
Porous Panels
Periodically clean porous panels with soap and water using a clean,
lint-free cloth. Isopropyl alcohol may be used to remove oil or grease.

Metering Pump Priming - Serials before G3 Wing
If air enters the system due to the fluid tank running dry during system
operation, the metering pump may not be capable of priming itself. To
draw fluid from the tank to prime the metering pump manifold and
remove any entrapped air between the metering pump and the fluid
tank:
1. Locate de-icing fluid drain on LH side of fuselage belly just forward
of fluid tank.
2. Sample de-icing fluid until fluid stream shows no evidence of air
bubbles for at least three seconds.
3. Set ICE PROTECT Mode Switch to MAXIMUM and verify
evidence of fluid at each of the protected locations.
4. If necessary, repeat steps 2 and 3
Metering Pump Priming - Serials with G3 Wing
If air entered the system due to the fluid tank running dry during
system operation, it may require several cycles of the priming pump to
prime the metering pumps.
In the event that the metering pump cannot prime itself, the priming
pump may be activated by cycling the ICE PROTECT System Switch,
10s ON, 10s OFF, to draw fluid from the tank to prime the metering
pump manifold and remove any entrapped air between the metering
pump and the fluid tank.
System Priming
For optimal performance, the system should be primed on the ground
by performing the preflight inspection to verify all protected surfaces
wet-out fully.

Section 10 – Safety Information
The Ice Protection System is not intended to remove ice from the
aircraft on the ground. Do not attempt to take off with frost, ice, or
snow on flying surfaces.
Flight into known icing is prohibited. The Ice Protection System has
not been evaluated in known icing conditions. Therefore, the affects of
known icing on the system is unknown. Its purpose is to provide some
protection from the effects of ice, should an unexpected encounter
with icing conditions occur. At the first indication of icing, the most
expeditious and safest course of exiting the icing conditions should be
taken. The decision should be based on weather briefings, recent pilot
reports, ATC observations, and may include course changes or
altitude changes.
During simulated icing encounters, stall speed increases of
approximately 12 knots in the clean configuration and 3 knots in the
landing configuration were observed. In addition, cruise speed was
reduced by at least 20 KCAS and the airplanes rate of climb
diminished by at least 20%.
Even with the protected flight surfaces totally clear of ice, performance
degradation will occur due to ice on unprotected regions. The amount
of the degradation cannot be accurately predicted and it is therefore,
depending on circumstances, advisable to increase approach and
landing speeds while using the Ice Protection System. Use extreme
caution during approach and landing, being alert to the first signs of
pre-stall buffet and an impending stall.

Section 1 - General
The airplane is equipped with an Honeywell KGP 560 Terrain
Awareness and Warning System that performs the functions of a
Class C Terrain Awareness and Warning System (TAWS) in
accordance with TSO C151b.
Incorporating much of the technology found in TAWS for air transport
aircraft, the KPG 560 supports:
• Alerting for premature descent.
• Alerting for excessive rate of climb/descent.
• Altitude callout (500 ft) and alerting within 5 nm of 2000 ft public
runways.
• Look-ahead
database.
algorithms
and
integrated
terrain/obstacle
The system consists of the 560 GA-EGPWS Processor mounted on
the underside of the pilot-side kickplate, a Terrain/Obstacle Database
integral to the processor, the Configuration Module integral to the
system’s wire harness, and the TAWS annunciator panel mounted on
the lower LH portion of the instrument panel.
The KGP 560 receives data from the GPS sensor, Transponder,
Primary Flight Display, and the Multifunction Display (MFD). Aural
alerts are communicated to the pilot via the GMA 340 Audio Panel. To
enhance the situational awareness to the pilot, color-coded terrain
display is interfaced on the MFD.
For specific MFD operational details refer to the Avidyne FlightMax
EX5000C Pilot’s Guide.

1. Do not use the Terrain Awareness Display for navigation of the
aircraft. The KGP 560 Terrain Awareness and Warning System is
intended to serve as a situational awareness tool only and may not
provide the accuracy fidelity on which to solely base terrain or
obstacle avoidance maneuvering decisions.
Section 3 - Emergency Procedures
Off-Airport Landings
1. For ditching or other off-airport landings, inhibit the Terrain
Awareness System functions by selecting the TERR INHIBIT
switch on the annunciator panel to prevent unwanted aural
alerting.
Section 4 - Normal Procedures
• Note •
Only vertical maneuvers are recommended responses to
warnings and alerts unless operating in VMC or the pilot
determines, using all available information and instruments,
that a turn, in addition to the vertical escape maneuver, is the
safest course of action.
During certain operations, warning thresholds may be
exceeded due to specific terrain or operating procedures.
During day VFR flight, these warnings may be considered as a
cautionary.
If the TAWS issues an alert when the Terrain Awareness
Display Page is not selected, a pop up message will appear
on the active display page of the MFD. To clear the alert, the
pilot must acknowledge the pop up message by pressing the
Soft Key next to the displayed “OK”.
Pilots are authorized to deviate from their current air traffic
control (ATC) clearance to the extent necessary to comply
with a TAWS warning.

Section 7 - Systems Description
The Honeywell KGP 560 Terrain Awareness and Warning System
compares GPS information from the Garmin Navigator (GPS 1) to the
integrated Terrain/Obstacle Database to produce a real-time model of
the surrounding terrain. This “virtual” picture is then sent to the MFD to
provide enhanced situational awareness to the pilot.
The system consists of the 560 GA-EGPWS Processor mounted on
the underside of the pilot-side kickplate, a Terrain/Obstacle Database
integral to the processor, the Configuration Module integral to the
system’s wire harness, and the TAWS annunciator panel mounted on
the lower LH portion of the instrument panel.
The 560 GA-EGPWS Processor is powered by 28 VDC through the 5amp SKYWATCH/TAWS circuit breaker on the Avionics Nonessential
Bus.
For a additional system information, refer to the KGP 560 & 860
EGPWS Pilot’s Guide, P/N 006-18254-001, Revision 04 or later.
System Constraints
• If there is no terrain data in the database for a particular area,
then TAWS alerting is not available for that area. The affected
area on the Terrain Awareness Display Page will be colored a
MAGENTA dot pattern.
• If the TAWS has been inhibited (e.g. the pilot selected TERR
INHIBIT) the system will not give aural alerts. The MFD will
display a purple message block with cyan text reading, “TAWS
Inhibited”.
• The TAWS will not be available and the TERR INOP
annunciator will illuminate if any of the following components
are inoperative: MFD, PFD, GPS 1, Transponder, or Attitude
Encoder.

into the Annunciator Panel. The panel consists of a momentary
pushbutton switch (SELF TEST), an illuminated pushbutton switch
(TERR INHIBIT), and three LEDS for Terrain Warning (TERR WARN),
Terrain Caution (TERR CAUT), Terrain Inoperative (TERR INOP).
• SELF TEST - Provides test function for the TAWS.
• TERR INHIBIT - To inhibit nuisance or unwanted warnings at
airports that are not in the system database, the pilot may
select the TERR INHIBIT switch. Although selection will inhibit
all TAWS visual and aural alerts, the Terrain Awareness Display
will remain functional with the message “Warnings Inhibited”
displayed on the MFD. When activated the switch will illuminate
amber.
• TERR INOP - Indicates the TAWS inoperative. When activated
the LED will illuminate amber.
• TERR CAUT - Indicates a possible terrain or obstacle conflict
within 40-60 seconds. When activated the LED will illuminate
amber.
• TERR WARN - Indicates a possible terrain or obstacle conflict
within 30 seconds. When activated the LED will illuminate red.
The annunciators are dimmed via the instrument panel lighting
dimmer switch. The TAWS annunciator panel is powered by 28 VDC
through the 2-amp ANNUN circuit breaker on the Essential Bus
Alert Priority
When any of the TAWS aural alerts are in progress, all aural TRAFFIC
alerts are inhibited.

MFD Terrain Awareness Display
• WARNING •
Do not use the Terrain Awareness Display for navigation of the
aircraft. The TAWS is intended to serve as a situational
awareness tool only and may not provide the accuracy fidelity
on which to solely base terrain or obstacle avoidance
maneuvering decisions.
To select the Terrain Awareness Display Page on the MFD, rotate the
page knob to TAWS.
Terrain and obstacle alerts are the most critical situations displayed by
TAWS. There are two levels of alerts:
• Caution Alert - Possible terrain or obstacle conflict within 4060 seconds. When triggered, the terrain or obstacle that
caused the alert is displayed in bright yellow. In addition, a
message describing the nature of the alert is presented in the
MFD message bar.
• Warning Alert - Possible terrain or obstacle conflict within 30
seconds. When triggered, the terrain or obstacle that caused
the alert is displayed in bright red. In addition, a message
describing the nature of the alert is presented in the message
bar
When a caution or warning alert is active, the display image
surrounding the target is enlarged somewhat to allow the terrain or
obstacle to be better seen on the display.
If a terrain or obstacle alert occurs while a page other than Terrain
Awareness Display Page is being displayed, a terrain or obstacle alert
message is displayed in the Message Bar. When the pilot
acknowledges this message, the MFD will automatically switch to the
Terrain Awareness Display Page.
The message bar will be removed from the display when the TAWS is
no longer in alert status, or if the pilot acknowledges the message from
the Terrain Awareness Display Page.

Geometric Altitude versus Measured Sea Level
An indication of MSL-G or Geometric Altitude may appear on the left
side of the MFD indicating the height above Measured Sea Level
(MSL) calculated from the GPS.
This data serves as the reference for color-coding for the Terrain
Awareness Display Page and as an input to the TAWS Look-Ahead
algorithm. Because it is derived from GPS, Geometric Altitude may
differ from corrected barometric altitude. Therefore, Geometric Altitude
may be in error by as much as 100 ft and should not be used for
navigation. MSL-G is presented solely to provide the pilot additional
situational awareness regarding the true MSL height upon which the
TAWS Terrain Display and Alerting is based.

Section 1 - General
Avidyne CMax™ Electronic Approach Charts allows the pilot to view
terminal procedure chart data on the EX5000C MFD. If the chart is
geo-referenced, an ownship symbol and flight plan legs can be
overlaid on the chart to further enhance the pilot’s situational
awareness. Most approach charts and airport diagrams are georeferenced; most arrival, departure, and miscellaneous charts are not.

Section 8 - Handling, Servicing & Maintenance
Propeller Servicing
The spinner and backing plate should be cleaned and inspected for
cracks frequently. Before each flight the propeller should be inspected
for nicks, scratches, and gouges. If found, they should be repaired as
soon as possible by a rated mechanic, since a nick or scratch causes
an area of increased stress which can lead to serious cracks or the
loss of a propeller tip.
Propeller blades are painted with a durable specialized coating that is
resistant to abrasion. If this coating becomes eroded, it is necessary to
repaint the blades to provide proper erosion protection. Painting
should be performed by an authorized propeller repair station.
It is permissible to perform a blade touch-up with aerosol paint in
accordance with Hartzell Propeller Owner’s Manual, p/n 145, revision
1 or later.

Section 1 - General
The G3 Wing is constructed in a conventional spar, rib, and shear
section arrangement. The upper and lower skins are bonded to the
spar, ribs, and aft shear web forming a torsion box that carries all of
the wing bending and torsion loads. The rear shear webs are similar in
construction but do not carry through the fuselage. The main spar is
laminated epoxy/carbon fiber in a C-section, and is continuous from
wing tip to wing tip. The wing spar passes under the fuselage below
the two front seats and is attached to the fuselage in two locations. Lift
and landing loads are carried by the single carry-through spar, plus a
pair of rear shear webs (one on each wing) attached to the fuselage.
G3 Wing geometry is slightly changed with an 1° increase in dihedral
which allows for the elimination of the aileron-rudder interconnect
system.
The CG Envelope (Center of Gravity Envelope) is expanded to allow
for slightly more forward loading at higher gross weights.
The main landing gear is moved slightly inboard and the strut angle
increased to achieve an increase in airplane height of 1.5 inches.
The ice protection system’s glycol tank is moved from the fuselage to
an integral tank on the left wing and the porous panels are lengthened
to cover the entire leading edge of the wing.
Other G3 Wing updates include:
• Increased fuel capacity,
• wing tip with integral, leading edge recognition lights.
• relocation of the fresh air inlets to the engine cowl and related
environmental system changes,
• improved trailing edge aerodynamics
• improved wing root fairings,
• relocation of the stall warning port.

Takeoff Distance
Conditions:
• Winds................................................................................................................ Zero
• Runway.........................................................................................Dry, Level, Paved
• Flaps................................................................................................................. 50%
• Power:
• Throttle ................................................................................................Full Open
• Mixture ...................................................................................... Set per Placard
Set prior to brake release for short field takeoff.
The following factors are to be applied to the computed takeoff distance for
the noted condition:
• Headwind - Subtract 10% from computed distance for each 12 knots headwind.
• Tailwind - Add 10% for each 2 knots tailwind up to 10 knots.
• Grass Runway, Dry - Add 20% to ground roll distance.
• Grass Runway, Wet - Add 30% to ground roll distance.
• Sloped Runway - Increase table distances by 22% of the ground roll distance at
Sea Level, 30% of the ground roll distance at 5000 ft, 43% of the ground roll
distance at 10,000 ft for each 1% of upslope. Decrease table distances by 7% of
the ground roll distance at Sea Level, 10% of the ground roll distance at 5000 ft,
and 14% of the ground roll distance at 10,000 ft for each 1% of downslope.
• Caution •
The above corrections for runway slope are required to be included herein.
These corrections should be used with caution since published runway slope
data is usually the net slope from one end of the runway to the other. Many
runways will have portions of their length at greater or lesser slopes than the
published slope, lengthening (or shortening) takeoff ground roll estimated
from the table.
• If brakes are not held while applying power, distances apply from point where full
throttle and mixture setting is complete.
• For operation in outside air temperatures colder than this table provides, use
coldest data shown.
• For operation in outside air temperatures warmer than this table provides, use
extreme caution.

smoothly continue power reduction to reach idle just prior to touchdown.
• Note •
The following factors are to be applied to the computed landing distance for
the noted condition:
• Headwind - Subtract 10% from table distances for each 13 knots headwind.
• Tailwind - Add 10% to table distances for each 2 knots tailwind up to 10 knots.
• Grass Runway, Dry - Add 20% to ground roll distance.
• Grass Runway, Wet - Add 60% to ground roll distance.
• Sloped Runway - Increase table distances by 27% of the ground roll distance for
each 1% of downslope. Decrease table distances by 9% of the ground roll
distance for each 1% of upslope.
• Caution •
The above corrections for runway slope are required to be included herein.
These corrections should be used with caution since published runway slope
data is usually the net slope from one end of the runway to the other. Many
runways will have portions of their length at greater or lesser slopes than the
published slope, lengthening (or shortening) landing ground roll estimated
from the table.
• For operation in outside air temperatures colder than this table provides, use
coldest data shown.
• For operation in outside air temperatures warmer than this table provides, use
extreme caution.

Airplane Weighing Procedures
A basic empty weight and center of gravity were established for this
airplane when the airplane was weighed just prior to initial delivery.
However, major modifications, loss of records, addition or relocation of
equipment, accomplishment of service bulletins, and weight gain over
time may require re-weighing to keep the basic empty weight and
center of gravity current. The frequency of weighing is determined by
the operator. All changes to the basic empty weight and center of
gravity are the responsibility of the operator. Refer to Section 8 for
specific servicing procedures.
1. Preparation:
a. Inflate tires to recommended operating pressures.
b.
Service brake reservoir.
c.
Drain fuel system.
d. Drain ice protection system.
e. Service engine oil.
f.
Move crew seats to the most forward position.
g. Raise flaps to the fully retracted position.
h. Place all control surfaces in neutral position.
i.
Verify equipment installation and location by comparison to
equipment list.
2. Leveling:
a. Level longitudinally with a spirit level placed on the pilot door
sill and laterally with of a spirit level placed across the door
sills. Alternately, level airplane by sighting the forward and aft
tool holes along waterline 95.9.
b.
Place scales under each wheel (minimum scale capacity, 500
pounds nose, 1000 pounds each main).
c.
Deflate the nose tire and/or shim underneath scales as
required to properly center the bubble in the level.

3. Weighing:
a. With the airplane level, doors closed, and brakes released,
record the weight shown on each scale. Deduct the tare, if
any, from each reading.
4. Measuring:
a. Obtain measurement ‘x’ by measuring horizontally along the
airplane center line (BL 0) from a line stretched between the
main wheel centers to a plumb bob dropped from the forward
side of the firewall (FS 100). Add 100 to this measurement to
obtain left and right weighing point arm (dimension ‘A’).
Typically, dimension ‘A’ will be in the neighborhood of 157.5.
b.
Obtain measurement ‘y’ by measuring horizontally and
parallel to the airplane centerline (BL 0), from center of
nosewheel axle, left side, to a plumb bob dropped from the
line stretched between the main wheel centers. Repeat on
right side and average the measurements. Subtract this
measurement from dimension ‘A’ to obtain the nosewheel
weighing point arm (dimension ‘B’).
5. Determine and record the moment for each of the main and nose
gear weighing points using the following formula:
Moment = Net Weight x Arm
6. Calculate and record the as-weighed weight and moment by
totaling the appropriate columns.
7. Determine and record the as-weighed C.G. in inches aft of datum
using the following formula:
C.G. = Total Moment ÷ Total Weight
8. Add or subtract any items not included in the as-weighed condition
to determine the empty condition. Application of the above C.G.
formula will determine the C.G for this condition.
9. Add the correction for engine oil (15 lb at FS 78.4), if the airplane
was weighed with oil drained. Add the correction for unusable fuel
(15.0 lb at FS 154.9) to determine the Basic Empty Weight and
Moment. Calculate and record the Basic Empty Weight C.G. by
applying the above C.G. formula.

10. Record the new weight and C.G. values on the Weight and
Balance Record.
The above procedure determines the airplane Basic Empty Weight,
moment, and center of gravity in inches aft of datum. C.G. can also be
expressed in terms of its location as a percentage of the airplane
Mean Aerodynamic Cord (MAC) using the following formula:
C.G. % MAC = 100 x (C.G. Inches – LEMAC) ÷ MAC
Where:
LEMAC = 133.1
MAC = 47.7

Section 7 - Systems Description
Airframe
Wings
The wing structure is constructed of composite materials producing
wing surfaces that are smooth and seamless. The wing cross section
is a blend of several high performance airfoils. A high aspect ratio
results in low drag. Each wing provides attach structure for the main
landing gear and contains a 47.25-gallon fuel tank.
The G3 Wing is constructed in a conventional spar, rib, and shear
section arrangement. The upper and lower skins are bonded to the
spar, ribs, and aft shear web forming a torsion box that carries all of
the wing bending and torsion loads. The rear shear webs are similar in
construction but do not carry through the fuselage. The main spar is
laminated epoxy/carbon fiber in a C-section, and is continuous from
wing tip to wing tip. The wing spar passes under the fuselage below
the two front seats and is attached to the fuselage in two locations. Lift
and landing loads are carried by the single carry-through spar, plus a
pair of rear shear webs (one on each wing) attached to the fuselage.
Rudder System
G3 Wing geometry is slightly changed with an increase in dihedral of
1° which allows for the elimination of the aileron-rudder interconnect
system.

Fuel System
An 92-gallon usable wet-wing fuel storage system provides fuel for
engine operation. The system consists of a 47.25-gallon capacity (46gallon usable) vented integral fuel tank and a fuel collector/sump in
each wing, a three position selector valve, an electric boost pump, and
an engine-driven fuel pump. Fuel is gravity fed from each tank to the
associated collector sumps where the engine-driven fuel pump draws
fuel through a filter and selector valve to pressure feed the engine fuel
injection system. The electric boost pump is provided for engine
priming and vapor suppression. Each integral wing fuel tank has a filler
cap in the upper surface of each wing for fuel servicing. Access panels
in the lower surface of each wing allow access to the associated wet
compartment (tank) for inspection and maintenance. Float-type fuel
quantity sensors in each wing tank supply fuel level information to the
fuel quantity indicators. Positive pressure in the tank is maintained
through a vent line from each wing tank. Fuel, from each wing tank,
gravity feeds through strainers and a flapper valve to the associated
collector tank in each wing. Each collector tank/sump incorporates a
flush mounted fuel drain and a vent to the associated fuel tank. The
engine-driven fuel pump pulls filtered fuel from the two collector tanks
through a three-position (LEFT-RIGHT-OFF) selector valve.
The selector valve allows tank selection. From the fuel pump, the fuel
is metered to a flow divider, and delivered to the individual cylinders.
Excess fuel is returned to the selected tank. A dual-reading fuelquantity indicator is located in the center console next to the fuel
selector in plain view of the pilot. Fuel shutoff and tank selection is
positioned nearby for easy access. Fuel system venting is essential to
system operation. Blockage of the system will result in decreasing fuel
flow and eventual engine fuel starvation and stoppage. Venting is
accomplished independently from each tank by a vent line leading to a
NACA-type vent mounted in an access panel underneath the wing
near each wing tip. The airplane may be serviced to a reduced
capacity to permit heavier cabin loadings. This is accomplished by
filling each tank to a tab visible below the fuel filler, giving a reduced
fuel load of 30.0 gallons usable in each tank (60 gallons total usable in
all flight conditions). Drain valves at the system low points allow
draining the system for maintenance and for examination of fuel in the
system for contamination and grade. The fuel must be sampled prior

to each flight. A sampler cup is provided to drain a small amount of
fuel from the wing tank drains, the collector tank drains, and the
gascolator drain. If takeoff weight limitations for the next flight permit,
the fuel tanks should be filled after each flight to prevent condensation.
Fuel Quantity Indicator
A dual reading 2¼” fuel quantity indicator is installed on the console
immediately forward of the fuel selector valve. The LEFT pointer
indicates left tank fuel quantity and sweeps a scale marked from 0 to
46 U.S. gallons in 5-gallon increments. The RIGHT pointer sweeps an
identical scale for the right tank. Each scale is marked with a yellow
arc from 0 to 14 U.S. gallons. The indicators are calibrated to read '0'
when no usable fuel remains. Each indicator also provides an output
signal to illuminate the FUEL caution light when the fuel quantity goes
below approximately 14 gallons in each tank. The fuel quantity
indications are derived from float-type fuel-level sensors installed in
each main tank. The indicator is internally lighted. 28 VDC for fuel
quantity system operation is supplied through the 5-amp FUEL QTY /
HOBBS circuit breaker on Main Bus 1.
• Note •
When the fuel tanks are 1/4 full or less, prolonged
uncoordinated flight such as slips or skids can uncover the
fuel tank outlets. Therefore, if operating with one fuel tank dry
or if operating on LEFT or RIGHT tank when 1/4 full or less, do
not allow the airplane to remain in uncoordinated flight for
periods in excess of 30 seconds.
Fuel Caution Light
The amber FUEL caution light in the annunciator panel comes on to
indicate a low fuel condition. The light is illuminated by switches in the
fuel quantity indicator if the fuel quantity in both tanks drops below
approximately 14 gallons (28 gallons total with tanks balanced in level
flight). Since both tanks must be below 14 gallons to illuminate the
light, the light could illuminate with as little as 14 gallons in one tank
during level flight if the other tank is allowed to run dry. If the FUEL
caution light comes on in flight, refer to the Fuel Quantity gages to
determine fuel quantity. The light is powered by 28 VDC through the 2amp ANNUN / ENGINE INST circuit breaker on the Essential Bus.

Section 7 - Systems Description
This airplane is equipped with a self-contained Artex ME406 406 MHz
ELT System. The transmitter unit is automatically activated upon
sensing a change of velocity along its longitudinal axis exceeding 4 to
5 feet per second. Once activated, the transmitter transmits VHF band
audio sweeps at 121.5 Mhz until battery power is gone. In addition, for
the first 24 hours of operation, a 406 MHz signal is transmitted at 50second intervals. This transmission lasts 440 ms and contains
identification data received by Cospas-Sarsat satellites. The
transmitted data is referenced in a database maintained by the
national authority responsible for ELT registration to identify the
beacon and owner. The ELT transmitter is installed immediately
behind the aft cabin bulkhead, slightly to the right of the airplane
centerline. The transmitter and antenna are accessible through the
avionics bay access panel along the aft portion of the RH fuselage or
the lower aft center access panel of baggage compartment. The main
transmitter control switch is labeled “ON” - “ARM”. The transmitter is in
the armed position for normal operations. A red LED annunciator
flashes when the ELT is transmitting. A battery pack consisting of two
“D” cell lithium batteries mounts to a cover assembly within the
transmitter to provide power to the transmitter. The expiration date of
the batteries are indicated on the outside of the ELT battery case and
recorded in the aircraft logs. A warning buzzer is mounted to the
transmitter mounting tray. When the ELT is activated, the buzzer
“beeps” periodically. This buzzer operates in tandem with the ELT
panel indicator and serves as a redundant annunciation. Power to the
buzzer is supplied by the ELT batteries. Serials 22-0002 thru 22-2978,
22-2980 thru 22-2991, and 22-2993 thru 22-3001; The ELT Remote
Switch and Control Panel Indicator (RCPI) is located below the circuit
breakers on the circuit breaker panel or Serials 22-2979, 22-2992, and
22-3002 and subsequent, 22T-0001 and subsequent, below the
Alternate Induction Air Control knob near the pilot’s right knee. The
RCPI provides test and monitoring functions for the transmitter. The
panel contains a switch labeled “ON” - “ARM”, and a red LED
annunciator. The red LED annunciator flashes when the ELT is
transmitting. Power to the LED is supplied by either the clock bus on
the MCU (Serials 22-1863 thru 22-2083) or by a 6V lithium battery in
the RCPI (Serials 22-2084 and subsequent, 22T-0001 and
subsequent).

Section 8 - Handling, Servicing & Maintenance
ELT and RCPI batteries must be inspected in accordance with the
Airplane Maintenances Manual, 5-20 - Scheduled Maintenance
Checks.
The ELT and RCPI batteries must be replaced upon reaching the date
stamped on the batteries, after an inadvertent activation of unknown
duration, or whenever the batteries have been in use for one
cumulative hour.
Inspection / Test
After setting transmitter switch to ARM position, the ELT automatically
enters a self-test mode. The self-test transmits a 406 MHz test coded
pulse that monitors certain system functions before shutting off. The
test pulse is ignored by any satellite that receives the signal, but the
ELT uses this pulse to check output power and frequency. Other
parameters of the ELT are checked and a set of error codes is
generated if a problem is found. The error codes are indicated by a
series of pulses on the transmitter LED, remote control panel indicator
LED, and alert buzzer.
• Note •
FAA regulations require that transmitter tests only be done
during the first 5 minutes of each hour and must not last for
more than 3 audio sweeps (1.5 seconds). If you are at a
location where there is an FAA control tower or other
monitoring facility, notify the facility before beginning the tests.
Never activate the ELT while airborne for any reason.
Operators may wish to use a low quality AM broadcast
receiver to determine if energy is being transmitted from the
antenna. When the antenna of the radio (tuning dial on any
setting) is held about 6 inches from the activated ELT antenna,
the ELT aural tone will be heard on the AM broadcast receiver.
This is not a measured check, but it does provide confidence
that the antenna is radiating sufficient power to aid search and
rescue. The aircraft’s VHF receiver, tuned to 121.5 MHz, may
also be used. This receiver, however, is more sensitive and
could pick up a weak signal even if the radiating ELT’s antenna
is disconnected. Thus it does not check the integrity of the ELT

Section 1 - General
The WAAS-enabled, Garmin 400W-Series GPS Navigator is capable
of providing primary navigation information for enroute, terminal, nonprecision, and precision approaches with typical position accuracies of
1 meter horizontally and 2 meters vertically.
The Wide Area Augmentation System (WAAS) consists of ground
reference stations positioned across the United States that monitor
GPS satellite data. Two master stations, located on either coast,
collect data from the reference stations and create a GPS correction
message. This correction accounts for GPS satellite orbit and clock
drift plus signal delays caused by the atmosphere and ionosphere.
The corrected data is then broadcast through geostationary satellites.
WAAS also provides the capability of quickly determining when signals
from a given satellite are wrong and removing that satellite from the
navigation solution using Receiver Autonomous Integrity Monitoring
(RAIM), a technology developed to assess the integrity of GPS
signals.
• Note •
WAAS satellite coverage is only available in North America.
User in other parts of the world can receive WAAS data,
however, the signal has not been corrected and thus does not
improve the accuracy of your receiver.
Models Covered
Two Garmin 400W-Series GPS Navigators are covered in this
publication; the GNC 420W and GNS 430W. Generally, both models
will be referred to as the Navigator, except where there are physical or
operational differences.

430W units with main software version 5.01 or above and valid
terrain and obstacle databases installed.
Garmin TERRAIN is a terrain awareness system incorporated into
GNS 430W units to increase situational awareness and aid in reducing
controlled flight into terrain. The TERRAIN function displays altitudes
of terrain and obstructions relative to the aircraft’s altitude and are
advisory in nature only. Individual obstructions may be shown if
available in the database, however, not all obstructions may be
available in the database and data may be inaccurate. TERRAIN
information should be used as an aid to visual acquisition and not use
to navigate or maneuver to avoid terrain.

Cirrus Airframe Parachute System (CAPS)
Deployment
The Cirrus Airframe Parachute System (CAPS) is designed to lower
the aircraft and its passengers to the ground in the event of a lifethreatening emergency. However, because CAPS deployment is
expected to result in damage to the airframe and, depending upon
adverse external factors such as high deployment speed, low altitude,
rough terrain or high wind conditions, may result in severe injury or
death to the aircraft occupants, its use should not be taken lightly.
Instead, possible CAPS activation scenarios should be well thought
out and mentally practiced by every SR22 pilot.
The following discussion is meant to guide your thinking about CAPS
activation. It is intended to be informative, not directive. It is the
responsibility of you, the pilot, to determine when and how the CAPS
will be used.
Deployment Scenarios
This section describes possible scenarios in which the activation of the
CAPS might be appropriate. This list is not intended to be exclusive,
but merely illustrative of the type of circumstances when CAPS
deployment could be the only means of saving the occupants of the
aircraft.
Mid-Air Collision
A mid-air collision may render the airplane unflyable by damaging the
control system or primary structure. If a mid-air collision occurs,
immediately determine if the airplane is controllable and structurally
capable of continued safe flight and landing. If it is not, CAPS
activation should be considered.
Structural Failure
Structural failure may result from many situations, such as:
encountering severe gusts at speeds above the airplane’s structural
cruising speed, inadvertent full control movements above the
airplane’s maneuvering speed, or exceeding the design load factor
while maneuvering. If a structural failure occurs, immediately
determine if the airplane is controllable and structurally capable of

continued safe flight and landing. If it is not, CAPS activation should be
considered.
Loss of Control
Loss of control may result from many situations, such as: a control
system failure (disconnected or jammed controls); severe wake
turbulence, severe turbulence causing upset, severe airframe icing, or
sustained pilot disorientation caused by vertigo or panic; or a spiral/
spin. If loss of control occurs, determine if the airplane can be
recovered. If control cannot be regained, the CAPS should be
activated. This decision should be made prior to your pre-determined
decision altitude (2,000’ AGL, as discussed below).
Landing Required in Terrain not Permitting a Safe Landing
If a forced landing is required because of engine failure, fuel
exhaustion, excessive structural icing, or any other condition CAPS
activation is only warranted if a landing cannot be made that ensures
little or no risk to the aircraft occupants. However, if the condition
occurs over terrain thought not to permit such a landing, such as: over
extremely rough or mountainous terrain, over water out of gliding
distance to land, over widespread ground fog or at night, CAPS
activation should be considered.
Pilot Incapacitation
Pilot incapacitation may be the result of anything from a pilot’s medical
condition to a bird strike that injures the pilot. If this occurs and the
passengers cannot reasonably accomplish a safe landing, CAPS
activation by the passengers should be considered. This possibility
should be explained to the passengers prior to the flight and all
appropriate passengers should be briefed on CAPS operation so they
could effectively deploy CAPS if required.
General Deployment Information
Deployment Speed
The maximum speed at which deployment has been demonstrated is
133 KIAS. Deployment at higher speeds could subject the parachute
and aircraft to excessive loads that could result in structural failure.
Once a decision has been made to deploy the CAPS, make all
reasonable efforts to slow to the minimum possible airspeed. However,

if time and altitude are critical, and/or ground impact is imminent, the
CAPS should be activated regardless of airspeed.
Deployment Altitude
No minimum altitude for deployment has been set. This is because the
actual altitude loss during a particular deployment depends upon the
airplane’s airspeed, altitude and attitude at deployment as well as
other environmental factors. In all cases, however, the chances of a
successful deployment increase with altitude. As a guideline, the
demonstrated altitude loss from entry into a one-turn spin until under a
stabilized parachute is 920 feet. Altitude loss from level flight
deployments has been demonstrated at less than 400 feet. With these
numbers in mind it might be useful to keep 2,000 feet AGL in mind as a
cut-off decision altitude. Above 2,000 feet, there would normally be
time to systematically assess and address the aircraft emergency.
Below 2,000 feet, the decision to activate the CAPS has to come
almost immediately in order to maximize the possibility of successful
deployment. At any altitude, once the CAPS is determined to be the
only alternative available for saving the aircraft occupants, deploy the
system without delay.
Deployment Attitude
The CAPS has been tested in all flap configurations at speeds ranging
from Vso to Va. Most CAPS testing was accomplished from a level
attitude. Deployment from a spin was also tested. From these tests it
was found that as long as the parachute was introduced to the free air
by the rocket, it would successfully recover the aircraft into its level
descent attitude under parachute. However, it can be assumed that to
minimize the chances of parachute entanglement and reduce aircraft
oscillations under the parachute, the CAPS should be activated from a
wings-level, upright attitude if at all possible.

Landing Considerations
After a CAPS deployment, the airplane will descend at less than 1700
feet per minute with a lateral speed equal to the velocity of the surface
wind. The CAPS landing touchdown is equivalent to ground impact
from a height of approximately 13 feet. While the airframe, seats, and
landing gear are designed to accommodate the stress, occupants
must be prepared for the landing. The overriding consideration in all
CAPS deployed landings is to prepare the occupants for the
touchdown in order to protect them from injury as much as possible.
Emergency Landing Body Position
The most important consideration for a touchdown with CAPS
deployed is to protect the occupants from injury, especially back injury.
Contacting the ground with the back offset attempting to open a door
or secure items increases the likelihood of back injury. All occupants
must be in the emergency landing body position well before
touchdown. After touchdown, all occupants should maintain the
emergency landing body position until the airplane comes to a
complete stop.
The emergency landing body position is assumed with tightened seat
belt and shoulder harness by placing both hands on the lap, clasping
one wrist with the opposite hand, and holding the upper torso erect
and against the seat backs. The seat cushions contain an aluminum
honeycomb core designed to crush under impact to absorb downward
loads and help protect the spine from compression injury.
Door Position
For most situations, it is best to leave the doors latched and use the
time available to transmit emergency calls, shut down systems, and
get into the Emergency Landing Body Position well before impact. The
discussion below gives some specific recommendations, however, the
pilot's decision will depend upon all factors, including time to impact,
altitude, terrain, winds, condition of airplane, etc.
There is the possibility that one or both doors could jam at impact. If
this occurs, to exit the airplane, the occupants will have to force open a
partially jammed door or break through a door window using the
Emergency Exit Hammer located in the lid of the center armrest. This
can significantly delay the occupants from exiting the airplane.

If the pilot elects to touchdown with a door opened, there are several
additional factors the pilot must consider: loss of door, possibility of
head injury, or injury from an object coming through the open door.
• If a door is open prior to touchdown in a CAPS landing, the
door will most likely break away from the airplane at impact.
• If the door is open and the airplane contacts the ground in a
rolled condition, an occupant could be thrown forward and
strike their head on the exposed door pillar. Contacting the
ground in a rolled condition could be caused by terrain that is
not level, contacting an obstacle such as a tree, or by transient
aircraft attitude.
• With a door open, it is possible for an object such as a tree limb
or flying debris to come through the opening and strike an
occupant.
• WARNING •
If it is decided to unlatch a door, unlatch one door only.
Opening only one door will provide for emergency egress as
well as reduce risks associated with ground contact. Typically,
this would be the copilot's door as this allows the other
occupants to exit first after the airplane comes to rest.

consider unlatching a door prior to assuming the emergency landing
body position in order to provide a ready escape path should the
airplane begin to sink.
Post Impact Fire
If there is no fire prior to touchdown and the pilot is able to shut down
the engine, fuel, and electrical systems, there is less chance of a post
impact fire. If the pilot suspects a fire could result from impact,
unlatching a door immediately prior to assuming the emergency
landing body position should be considered to assure rapid egress.
Ground Gusts
If it is known or suspected that ground gusts are present in the landing
zone, there is a possibility that the parachute could drag the airplane
after touchdown, especially if the terrain is flat and without obstacles.
In order to assure that the occupants can escape the airplane in the
timeliest manner after the airplane comes to rest, the pilot may elect to
unlatch the copilot's door for the CAPS landing. Occupants must be in
the Emergency Landing Body Position for touchdown. Occupants must
not loosen seat belts until the airplane comes to rest. When the
airplane comes to rest, the occupants should exit the airplane and
immediately move upwind to prevent a sudden gust from dragging the
airplane in their direction.

Taxiing, Steering, and Braking Practices
Cirrus aircraft use a castering nose wheel and rely on aerodynamic
forces and differential braking for directional control while taxiing.
Proper braking practices are therefore critical to avoid potential
damage to the brakes.
The most common cause of brake damage and/or failure is the
creation of excessive heat through improper braking practices. Pilots
unaccustomed to free castering nose wheel steering may be inclined
to “ride” the brakes to maintain constant taxi speeds and use the
brakes excessively for steering.
Proper Operating Practices
When taxiing, directional control is accomplished with rudder
deflection and intermittent braking (toe taps) as necessary. Use only
as much power as is necessary to achieve forward movement.
Deceleration or taxi speed control using brakes but without a reduction
in power will result in increased brake temperature.
On flat, smooth, hard surfaces, do not exceed 1000 RPM maximum
continuous engine speed for taxi. Power settings slightly above 1000
RPM are permissible to start motion, for turf, soft surfaces, and on
inclines. Use minimum power to maintain constant taxi speed.
“Riding the brakes” while taxiing is similar to driving a car with one foot
on the brake and one foot on the gas. This causes a continuous build
up of energy that would otherwise be moving the airplane.
Observe the following operating practices:
• Verify that the parking brake is completely disengaged before
taxi.
• The rudder is effective for steering on the ground and should be
used.
• Use only as much power (throttle) as is necessary to achieve
forward movement. Keep in mind, any additional power added
with the throttle will be absorbed in the brakes to maintain
constant speed.
• Use rudder deflection and the minimum necessary inputs of
differential braking to achieve directional control.

Safety Information
• Do not “ride the brakes”. Pilots should consciously remove
pressure from the brakes while taxiing. Failure to do so results
in excessive heat buildup, premature brake wear, and
increased possibility of brake failure or fire.
• Avoid unnecessary high-speed taxiing. High-speed taxiing may
result in excessive demands on the brakes, increased brake
wear, and the possibility of brake failure or fire.
• Brakes have a large energy absorbing capacity; therefore,
cooling time should be considered. Energy absorbed during a
few seconds of deceleration can take up to an hour to dissipate.
Always allow adequate cooling time after brake use.
• Allow a cooling period following a high-energy braking event.
High-energy braking can include an aborted takeoff or the
equivalent energy required for a Maximum Gross Weight fullstop from 70 knots in less than 1000 feet.
Brake Maintenance
The brake assemblies and linings should be checked at every oil
change (50 hours) for general condition, evidence of overheating, and
deterioration. Serials 0002 thru 3450 before SB 2X-05-01: At every
annual/100-hour inspection the brakes should be disassembled, the
brake linings should be checked and the O-rings must be replaced.
Refer to Section 8, Handling, Servicing, and Maintenance for specific
servicing information on the Brake System.
