WARNINGS,
CAUTIONS, & NOTES
WARNING: Navigation and terrain separation must NOT be predicated upon the use of the terrain function.
The G1000 Terrain Proximity feature is NOT intended to be used as a primary reference for terrain avoidance
and does not relieve the pilot from the responsibility of being aware of surroundings during flight. The Terrain
Proximity feature is only to be used as an aid for terrain avoidance and is not certified for use in applications
requiring a certified terrain awareness system. Terrain data is obtained from third party sources. Garmin is
not able to independently verify the accuracy of the terrain data.
WARNING: The displayed minimum safe altitudes (MSAs) are only advisory in nature and should not be relied
upon as the sole source of obstacle and terrain avoidance information. Always refer to current aeronautical
charts for appropriate minimum clearance altitudes.
WARNING: The altitude calculated by G1000 GPS receivers is geometric height above Mean Sea Level and could
vary significantly from the altitude displayed by pressure altimeters, such as the GDC 74A Air Data Computer,
or other altimeters in aircraft. GPS altitude should never be used for vertical navigation. Always use pressure
altitude displayed by the G1000 PFD or other pressure altimeters in aircraft.
WARNING: Do not use outdated database information. Databases used in the G1000 system must be updated
regularly in order to ensure that the information remains current. Pilots using any outdated database do so
entirely at their own risk.
WARNING: Do not use basemap (land and water data) information for primary navigation. Basemap data is
intended only to supplement other approved navigation data sources and should be considered as an aid to
enhance situational awareness.
WARNING: Traffic information shown on the G1000 Multi Function Display is provided as an aid in visually
acquiring traffic. Pilots must maneuver the aircraft based only upon ATC guidance or positive visual acquisition
of conflicting traffic.
WARNING: Use of the Stormscope is not intended for hazardous weather penetration (thunderstorm penetration).
Stormscope information, as displayed on the G1000 MFD, is to be used only for weather avoidance, not
penetration.
WARNING: GDL 69 Weather should not be used for hazardous weather penetration. Weather information
provided by the GDL 69 is approved only for weather avoidance, not penetration.
Garmin G1000 Cockpit Reference Guide for the Cessna Nav III
WARNINGS,
CAUTIONS, & NOTES
WARNING: NEXRAD weather data is to be used for long-range planning purposes only. Due to inherent delays
in data transmission and the relative age of the data, NEXRAD weather data should not be used for short-range
weather avoidance.
WARNING: The Garmin G1000, as installed in Cessna Nav III aircraft, has a very high degree of functional
integrity. However, the pilot must recognize that providing monitoring and/or self-test capability for all
conceivable system failures is not practical. Although unlikely, it may be possible for erroneous operation to
occur without a fault indication shown by the G1000. It is thus the responsibility of the pilot to detect such an
occurrence by means of cross-checking with all redundant or correlated information available in the cockpit.
WARNING: For safety reasons, G1000 operational procedures must be learned on the ground.
WARNING: The United States government operates the Global Positioning System and is solely responsible
for its accuracy and maintenance. The GPS system is subject to changes which could affect the accuracy
and performance of all GPS equipment. Portions of the Garmin G1000 utilize GPS as a precision electronic
NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, information presented by the G1000 can be misused
or misinterpreted and, therefore, become unsafe.
WARNING: To reduce the risk of unsafe operation, carefully review and understand all aspects of the G1000
Pilot’s Guide documentation. Thoroughly practice basic operation prior to actual use. During flight operations,
carefully compare indications from the G1000 to all available navigation sources, including the information
from other NAVAIDs, visual sightings, charts, etc. For safety purposes, always resolve any discrepancies before
continuing navigation.
WARNING: The illustrations in this guide are only examples. Never use the G1000 to attempt to penetrate a
thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms, and the Airman’s Information Manual
(AIM) recommend avoiding “by at least 20 miles any thunderstorm identified as severe or giving an intense
radar echo.”
CAUTION: The GDU 1040 and GDU 1044B PFD/MFD displays use a lens coated with a special anti-reflective
coating that is very sensitive to skin oils, waxes, and abrasive cleaners. CLEANERS CONTAINING AMMONIA
WILL HARM THE ANTI-REFLECTIVE COATING. It is very important to clean the lens using a clean, lint-free cloth
and an eyeglass lens cleaner that is specified as safe for anti-reflective coatings.
Garmin G1000 Cockpit Reference Guide for the Cessna Nav III
WARNINGS,
CAUTIONS, & NOTES
CAUTION: The Garmin G1000 does not contain any user-serviceable parts. Repairs should only be made by
an authorized Garmin service center. Unauthorized repairs or modifications could void both the warranty and
the pilot’s authority to operate this device under FAA/FCC regulations.
NOTE: When using Stormscope, there are several atmospheric phenomena in addition to nearby thunderstorms
that can cause isolated discharge points in the strike display mode. However, clusters of two or more discharge
points in the strike display mode do indicate thunderstorm activity if these points reappear after the screen has
been cleared.
NOTE: All visual depictions contained within this document, including screen images of the G1000 panel and
displays, are subject to change and may not reflect the most current G1000 system. Depictions of equipment
may differ slightly from the actual equipment.
NOTE: This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
NOTE: The GDU 1040 and GDU 1044B PFD/MFD may require a warm-up time of up to 30 minutes when exposed
to -40˚C for an extended period. A warm-up time of up to 15 minutes may be required when exposed to -30˚C
for an extended period.
NOTE: This product, its packaging, and its components contain chemicals known to the State of California to
cause cancer, birth defects, or reproductive harm. This notice is being provided in accordance with California’s
Proposition 65. If you have any questions or would like additional information, please refer to our web site at

Garmin G1000 Cockpit Reference Guide for the Cessna Nav III
SECTION 1
SYSTEM OVERVIEW
SECTION 1: SYSTEM OVERVIEW
The purpose of this Cockpit Reference Guide is
to provide the pilot a resource with which to find
operating instructions on the major features of the
G1000 system more easily. It is not intended to be a
comprehensive operating guide. Complete operating
procedures for the complete system are found in the
Garmin G1000 Pilot’s Guide for the Cessna Nav III (19000498-01).
This guide gives the pilot abbreviated operating
instructions for the Primary Flight Display (PFD), Multi
Function Display (MFD), and the GMA 1347 Audio Panel

VERTICAL NAVIGATION
The G1000 system can use altitude constraints
associated with lateral waypoints to give guidance for
vertical navigation. These altitudes are, depending on the
specific instance, entered by the pilot or retrieved from the
published altitudes in the navigation database.
The navigation database only contains altitudes
for procedures that call for “Cross at” altitudes. If the
procedure states “Expect to cross at,” then the altitude will
not be in the database. In this case the altitude may be
entered manually.
NOTE: All arrival procedure altitudes contained in
the navigation database are for turbojet aircraft
only. If necessary, alter or enter altitudes to be
consistent with the requirements of the Cessna
Nav III aircraft.
When activating or loading an arrival or approach
procedure into an active flight plan, the VNAV ‘ALT’ fields
will be populated with any altitudes that can be retrieved
from the navigation database.
Selected Page
Since altitudes loaded with an arrival procedure are
published only for turbojet aircraft, the altitudes are
displayed as white text indicating that the altitudes are
displayed for reference only. An arrival waypoint altitude
may be used (or “designated”) as is, or changed to a
different altitude. An altitude is designated by placing the
cursor on the desired altitude and pressing the ENT Key
or entering a different value and press the ENT Key. The
altitude will now be displayed as blue text, indicating that
the altitude is now designated to give vertical speed and
deviation guidance.
Altitudes associated with an approach procedure are
“auto-designated”. This means the system will automatically
use the altitudes loaded with the approach for giving vertical
speed and deviation guidance. Note that these altitudes
will be displayed as blue text up to, but not including the
FAF. The FAF will always be a “reference only” altitude and
cannot be designated.
Altitudes that have been designated for use in vertical
guidance may also be made “non-designated” by placing the
cursor over the desired altitude and pressing the CLR Key.
Other displayed altitudes may change due to re-calculations

or rendered invalid as a result of manually changing an
altitude to a non-designated altitude.
To help interpret the meanings of how the altitudes are
presented, keep the following points in mind:
Refer to Figure 1-8 and Table 1-1 for more detail
regarding the significance of text size and color.
• When the altitude is displayed in light blue, the
system is using that altitude (designated) to determine vertical speed and deviation guidance.
• When the altitude is displayed in white, it is not
being used by the system (non-designated) to
determine the vertical speed and deviation guidance.
• An altitude displayed as small text is an altitude
that is published in the navigation database.
• Altitudes displayed as a light blue halftone cannot
be used in the current vertical navigation calculations.

DATABASE UPDATES
The G1000 System uses Secure Digital (SD) cards to
load and store various types of data. For basic flight operations, SD cards are required for database storage as well
as Jeppesen aviation and ChartView database updates.
The following procedures pertain to updating the
G1000 system with SD cards obtained as outlined in
Appendix B of the G1000 Cessna Nav III Pilot’s Guide.

MFD or PFD, a Supplemental Data Card containing identical database versions must be kept in each display unit.
NOTE: The data contained in the terrain and
obstacle databases comes from government
agencies. Garmin accurately processes and
cross-validates the data, but cannot guarantee
the accuracy and completeness of the data.
1) Insert one SD card in the bottom card slot of
the MFD and one in the bottom card slot of the
PFD. The SD card containing the ChartView or
FliteCharts database must be inserted into the
bottom slot on the MFD.
2) Apply power to the G1000 System. View the
MFD power-up splash screen. Check that the
databases are initialized and displayed on the

From the Lean Display, the pilot can utilize the CYL
SLCT and ASSIST softkeys to obtain information about
specific cylinders. Pressing the CYL SLCT (Cylinder
Select) Softkey cycles through the cylinders (i.e., changes
the cylinder indicated on the bar graphs in light blue).
This softkey is disabled when the ASSIST Softkey is
pressed or when a cylinder experiences a caution or
warning condition; the softkey remains disabled until the
temperature returns to normal.
Garmin G1000 Cockpit Reference Guide for the Cessna Nav III
SECTION 3 – ENGINE

The ASSIST Softkey aids in the leaning process by
identifying the peak of the first cylinder whose temperature
falls. If the temperature of the peaked cylinder exceeds
the peak value, the peak value is not updated. Press the
ASSIST Softkey to stop peak monitoring.
Normally-aspirated Aircraft
For normally-aspirated aircraft, when a cylinder peaks,
its peak is represented by a hollow block on the EGT Bar
Graph. The EGT readout for the peaked cylinder, indicated on the bar graph in light blue, appears directly beneath
the bar graph. The system automatically switches to the
first peak obtained and displays the temperature deviation
from peak (∆PEAK) in degrees Fahrenheit (°F) below the
EGT readout.
Turbocharged Aircraft
Leaning for turbocharged aircraft is done with reference to the Turbine Inlet Temperature (TIT). When the
temperature peaks, the numeric readout (∆PEAK) appears
below the TIT Indicator and displays the difference between peak and current TITs, in degrees Fahrenheit (°F).
If a peak is not displayed, underscores are shown until
one is established.
3.3
The System Display is accessed by pressing the
ENGINE Softkey followed by the SYSTEM Softkey and
shows critical engine, fuel, and electrical parameters.
Fuel calculations are based on the fuel flow totalizer
and the displayed fuel remaining, adjusted by the pilot
using the following softkeys:
• RST FUEL – Resets totalizer-based fuel remaining
(GAL REM) to the aircraft’s fuel capacity and the fuel
used (GAL USED) to zero
• GAL REM – Gives access to softkeys for adjusting
the amount of fuel remaining for purposes of fuel
calculations
Fuel remaining can be adjusted in one or ten-gallon
increments using the appropriate softkeys. Softkeys also
allow entering the full tank quantity for the aircraft or the
tab quantity, which is 35 gallons (Models 172R and 172S)
or 64 gallons (Models 182T, T182T, 206H, and T206H).

NOTE: Fuel calculations do not use the aircraft
fuel quantity indicators and are calculated from
the last time the fuel was reset.
NOTE: The pilot should refer to the Pilot’s
Operating Handbook (POH) for fuel values and
limitations. The displayed fuel remaining can be
adjusted up to 53 gal (Models 172R, 172S) or 87

FLIGHT DIRECTOR MODES
Flight director modes are normally selected
independently for the pitch and roll axes. Unless
otherwise specified, all mode keys are alternate action
(i.e., press on, press off). In the absence of specific mode
selection, the flight director reverts to the default pitch
and/or roll mode(s).
Armed modes are annunciated in white and active in
green in the AFCS Status Box. Under normal operation,
when the control for the active flight director mode is
pressed, the flight director reverts to the default mode(s)
for the axis(es). Automatic transition from armed to active
mode is indicated by the white armed mode annunciation
moving to the green active mode field and flashing for ten
seconds.
A flashing yellow mode annunciation and annunciator
light indicate loss of sensor (AHRS, ADC, IAU) or

Changing the Pitch Reference
When the flight director is activated (the FD Key is
pressed), Pitch Hold Mode is selected by default. Pitch
Hold Mode is indicated as the active pitch mode by the
green annunciation ‘PIT’. This mode may be used for
climb or descent to the Selected Altitude (shown above
the Altimeter), since Selected Altitude Capture Mode is
automatically armed when the mode is activated.
When operating in Pitch Hold Mode, the pitch
reference can be adjusted by:
• Using the NOSE UP/NOSE DN Keys
• Pressing the CWS Button, hand-flying the aircraft
to establish a new pitch reference, then releasing
the CWS Button
In Pitch Hold Mode, the flight director maintains a
constant pitch attitude, the pitch reference. The pitch
reference is set to the aircraft attitude at the moment
of mode selection. If the aircraft pitch attitude exceeds
the flight director pitch command limitations, the flight
director commands a pitch angle equal to the nose-up/

Selected Altitude Capture Mode (ALTS)
Selected Altitude Capture Mode arms automatically
when the flight director is in Pitch Hold, Vertical Speed,
Flight Level Change, or Go Around Mode. This mode
is also armed automatically under Vertical Path Tracking
Mode when the Selected Altitude is to be captured
instead of the VNAV Target Altitude. The white ‘ALTS’
annunciation indicates Selected Altitude Capture Mode is
armed (see Figure 6-5 for example).
The ALT Knob is used to set the Selected Altitude,
shown above the Altimeter until Selected Altitude Capture
Mode becomes active.
As the aircraft nears the Selected Altitude, the flight
director automatically transitions to Selected Altitude
Capture Mode with Altitude Hold Mode armed (Figure
6-7). This automatic transition is indicated by the green
‘ALTS’ annunciation flashing for up to ten seconds and the
appearance of the white ‘ALT’ annunciation. The Selected
Altitude is shown as the Altitude Reference beside the
‘ALTS’ annunciation.
At 50 ft from the Selected Altitude, the flight director
automatically transitions from Selected Altitude Capture
to Altitude Hold Mode and holds the Selected Altitude
(shown as the Altitude Reference). As Altitude Hold Mode
becomes active, the white ‘ALT’ annunciation moves to the
active pitch mode field and flashes green for ten seconds

Altitude Hold Mode (ALT)
Altitude Hold Mode can be activated by pressing the
ALT Key; the flight director maintains the current aircraft
altitude (to the nearest ten feet) as the Altitude Reference.
The flight director’s Altitude Reference is shown in the
AFCS Status Box and is independent of the Selected
Altitude, displayed above the Altimeter. Altitude Hold
Mode active is indicated by a green ‘ALT’ annunciation in
the AFCS Status Box.
Altitude Hold Mode is automatically armed when
the flight director is in Selected Altitude Capture Mode.
Selected Altitude Capture Mode automatically transitions
to Altitude Hold Mode when the altitude error is less than
50 ft. In this case, the Selected Altitude becomes the flight
director’s Altitude Reference.
Changing the Altitude Reference
NOTE: Turning the ALT Knob while in Altitude
Hold Mode changes the Selected Altitude, but
not the flight director’s Altitude Reference and
does not cancel the mode.
With the CWS Button depressed, the aircraft can be

Vertical Navigation Modes (VPTH, ALTV)
NOTE: Pressing the CWS Button while Vertical

Button.
NOTE: VNAV flight director pitch modes are
available only in conjunction with GPS roll
modes.
NOTE: The Selected Altitude takes precedence
over any other vertical constraints.
Vertical Navigation (VNAV) flight control is available
for enroute/terminal cruise and descent operations when
VNAV has been enabled and a VNAV flight plan (with at
least one vertical waypoint) or vertical direct-to has been
activated. Refer to the GPS Navigation Section for more
information on VNAV flight plans. The flight director may
be armed for VNAV at any time, but no target altitudes are
captured during a climb.
The Command Bars provide vertical profile guidance
based on specified altitudes (entered manually or loaded
from the database) at waypoints in the active flight plan
or vertical direct-to. The appropriate VNAV flight control
modes are sequenced by the flight director to follow the
path defined by the vertical profile. Upon reaching the
last waypoint in the VNAV flight plan, the flight director
transitions to Altitude Hold Mode and cancels any armed
VNAV modes.
When a vertical profile (VNAV flight plan) is active and
the VNV Key is pressed, Vertical Path Tracking Mode is
armed in preparation for descent path capture. ‘VPTH’ (or
‘/V’ when Glidepath or Glideslope Mode is concurrently
armed) is annunciated in white in addition to previously
armed modes. If applicable, the appropriate altitude
capture mode is armed for capture of the next VNAV
Target Altitude (ALTV) or the Selected Altitude (ALTS),
whichever is greater.
Figure 6-10 Vertical Path Tracking Armed Annunciations
Prior to descent path interception, the Selected Altitude
must be set below the current aircraft altitude by at least
75 ft. For the flight director to transition from Altitude
Hold to Vertical Path Tracking Mode, acknowledgment is
required within five minutes of descent path capture by:
• Pressing the VNV Key
• Adjusting the Selected Altitude
If acknowledgment is not received within one minute of
descent path interception, the white ‘VPTH’ annunciation
and the VNV Key annunciator light start to flash. Flashing
continues until acknowledged or the descent path is
intercepted. If the descent is not confirmed by the time of
interception, Vertical Path Tracking Mode remains armed

appropriate altitude capture modes are armed for possible
descent profile recapture if the vertical deviation:
• Exceeds 200 ft during an overspeed condition
• Experiences a discontinuity exceeding 200 ft due to
a flight plan change
• Becomes invalid due to excessive cross-track error,
track angle error
• Cannot be computed for a leg type (such as a hold

The following circumstances cause mode reversion
without arming Vertical Path Tracking Mode:
• Navigation source manually changed from GPS

VNAV flight control is selected. If the VS or FLC Key
is pressed while Vertical Path Tracking Mode is selected,
Vertical Path Tracking Mode reverts to armed along with
the appropriate altitude capture mode to allow profile recapture.
Figure 6-13 Flight Level Change VNAV Non-Path Descent
To prevent immediate profile re-capture, the following
must be satisfied:
• At least ten seconds have passed since the non-path
transition was initiated
• Vertical deviation from the profile has exceeded 250
ft, but is now less than 200 ft
Pressing the VNV Key twice re-arms Vertical Path
Tracking for immediate profile re-capture.
VNAV Target Altitude Capture Mode (ALTV)
NOTE: Armed VNAV Target Altitude and Selected
Altitude capture modes are mutually exclusive.
However, Selected Altitude Capture Mode is
armed implicitly (not annunciated) whenever
VNAV Target Altitude Capture Mode is armed.
This ensures the Selected Altitude is not violated
during a change from VNAV Target Altitude
Capture to Selected Altitude Capture Mode close
to Selected Altitude interception.
VNAV Target Altitude Capture is analogous to Selected
Altitude Capture Mode and is armed automatically
after the VNV Key is pressed and the next VNAV Target
Altitude is to be intercepted before the Selected Altitude.
The annunciation ‘ALTV’ indicates that the VNAV Target
Altitude is to be captured. VNAV Target Altitudes are
shown in the active flight plan or vertical direct-to, and
can be entered manually or loaded from a database (see the
GPS Navigation Section for details). At the same time as
“TOD within 1 minute” is annunciated in the Navigation
Data Box, the VNAV Target Altitude is displayed above the
Vertical Speed Indicator (see Figure 6-12). VNAV Target
Altitudes can be modified until VNAV Target Altitude
Capture Mode becomes active.
As the aircraft nears the VNAV Target Altitude, the
flight director automatically transitions to VNAV Target
Altitude Capture Mode with Altitude Hold Mode armed.
This automatic transition is indicated by the green ‘ALTV’
annunciation flashing for up to ten seconds and the
appearance of the white ‘ALT” annunciation. The VNAV
Target Altitude is shown as the Altitude Reference beside
the ‘ALTV’ annunciation.
At 50 ft from the VNAV Target Altitude, the flight
director automatically transitions from VNAV Target
Altitude Capture to Altitude Hold Mode and tracks the
level leg. As Altitude Hold Mode becomes active, the
white ‘ALT’ annunciation moves to the active pitch mode
field and flashes green for ten seconds to indicate the
automatic transition. The flight director automatically
arms Vertical Path Tracking, allowing upcoming descent
legs to be captured and subsequently tracked.

AUTOPILOT OPERATION
NOTE: Refer to the AFM for specific instructions
regarding emergency procedures.
Cessna Nav III’s autopilot operates flight control
surface servos to provide automatic flight control. The
autopilot controls the aircraft pitch and roll attitudes
following commands received from the flight director.
Pitch autotrim provides trim commands to the pitch trim
adapter to relieve any sustained effort required by the
pitch servo.
Flight Control
Pitch and roll commands are provided to the servos,
based on the active flight director modes. Servo motor
control limits the maximum servo speed and torque.
The servo mounts are equipped with slip-clutches set to
certain values. This allows the servos to be overridden in
case of an emergency.
Pitch Axis and Pitch Trim
The autopilot pitch axis uses pitch rate to stabilize the
aircraft pitch attitude during upsets and flight director
maneuvers. Flight director pitch commands are rate- and
attitude-limited, combined with pitch damper control, and
sent to the pitch servo motor. The pitch servo measures
the output effort (torque) and provides this signal to the
pitch trim adapter. The pitch trim servo commands the
motor to reduce the average pitch servo effort.
When the autopilot is not engaged, the pitch trim servo
may be used to provide manual electric trim. This allows
the aircraft to be trimmed using a control stick switch
rather than the trim wheel. Manual trim commands are
generated with the MET Switch. Trim speeds are scheduled
with airspeed to provide more consistent response.
6-22
Roll Axis
The autopilot roll axis uses roll rate to stabilize aircraft
roll attitude during upsets and flight director maneuvers.
The flight director roll commands are rate- and attitudelimited, combined with roll damper control, and sent to
the roll servo motor.
Engaging the Autopilot
NOTE: Autopilot engagement/disengagement is
not equivalent to servo engagement/disengagement. Use the CWS Button to disengage the
pitch and roll servos while the autopilot remains
active.
When the AP Key is pressed, the autopilot and flight
director (if not already engaged) are activated. Engagement
is indicated by a green ‘AP’ annunciation in the center of
the AFCS Status Box. The flight director engages in Pitch
and Roll Hold modes when initially activated.

SECTION 6 – AUTOMATIC
FLIGHT CONTROL
Control Wheel Steering
During autopilot operation, the aircraft may be handflown without disengaging the autopilot. Pressing and
holding the CWS Button disengages the pitch and roll
servos from the flight control surfaces and allows the
aircraft to be hand-flown. At the same time, the flight
director is synchronized to the aircraft attitude during the
maneuver. The ‘AP’ annunciation is temporarily replaced
by ‘CWS’ in white for the duration of CWS maneuvers.
In most scenarios, releasing the CWS Button reengages
the autopilot with a new reference. Refer to the flight
director modes section for CWS behavior in each mode.
The autopilot may be manually disengaged by pushing
the AP DISC or GA Switch or the AP Key on the MFD.
Manual disengagement is indicated by a five-second
flashing yellow ‘AP’ annunciation and a three-second
autopilot disconnect aural alert. The AP DISC or MET
Switch may be used to cancel the aural alert.

This section provides a scenario-based set of procedures
showing various GFC 700 AFCS modes used during a
flight. In this scenario, the aircraft departs Reid-Hillview
Airport (KRHV) from runway 13L, enroute to Fresno
Yosemite International Airport (KFAT). Per the filed flight
plan, the aircraft climbs to an altitude of 7000 feet MSL at
a heading of 070° to intercept airway V107.
Airway V107 is flown to Panoche VORTAC (PXN)
using VOR navigation, then airway V230 is flown using a
GPS flight plan. On this leg, the aircraft descends to 3000
feet prior to reaching Clovis VORTAC (CZQ) and the ILS
approach to R29R at KFAT is loaded. The ILS approach is
flown and a missed approach is executed.
Climbing to the Selected Altitude and flying
an assigned heading:
1) Upon takeoff, set the Selected Altitude to 7000
feet using the ALT Knob.
To have the autopilot capture this altitude, use
Pitch Hold, Vertical Speed, or Flight Level Change
Mode. In this example, Vertical Speed Mode is
used.
2) Upon reaching the desired vertical speed of 1000
fpm, enable the flight director in Vertical Speed
Mode.

NAVIGATING A FLIGHT PLAN
The following discussion is an example of navigating a
vertical flight plan with the optional WAAS capable GPS
system. A lateral flight plan (LNAV) would be navigated
in much the same way, but would not include the vertical
guidance after the Initial Approach Fix.
The example is a flight plan from KMCI to KDFW. An
LPV (WAAS) approach is used for runway 17L. See the
Automatic Flight Control section for a discussion on flying
a vertical flight plan with the autopilot coupled.

precipitation characteristics (hail vs. rain, etc).
• An individual NEXRAD site cannot depict high
altitude storms at close ranges, and has no
information about storms directly over the site.
• The resolution of displayed NEXRAD data is 4
square kilometers. Therefore, when zoomed in on
the display, each square block is 2 kilometers on
each side. The intensity level reflected by the square
will be the highest level sampled within the square
area.
ECHO TOP – Press the ECHO TOP Softkey to show
the location, elevation, and direction the highest
radar echo. This may not indicate the top of a

OPERATION
11.1 REVERSIONARY MODE
Should a system detected failure occur in either display,
the G1000 automatically enters reversionary mode. In
reversionary mode, critical flight instrumentation is
combined with engine instrumentation on the remaining
display. Minimal navigation capability is available on the
reversionary mode display.
Normal PFD Display
Reversionary display mode can also be manually
activated by the pilot if the system fails to detect a display
problem. The reversionary mode is activated manually
by pressing the red DISPLAY BACKUP button on the
bottom of the audio panel (GMA 1347). Pressing the red
DISPLAY BACKUP button again deactivates reversionary
mode.
NOTE: The Cessna Pilot’s Operating Handbook
(POH) always takes precedence over the
information found in this section.

OPERATION
11.2 ABNORMAL COM OPERATION
When a COM tuning failure is detected by the system,
the emergency frequency (121.500 MHz) is automatically
loaded into the active frequency field of the COM radio
for which the tuning failure was detected. In the event of
a dual display failure, the emergency frequency (121.500
MHz) automatically becomes the active frequency to the
pilot through the pilot headset.
11.3 UNUSUAL ATTITUDES
The PFD will ‘declutter’ when the aircraft enters an
unusual attitude. Only the primary functions will be
displayed in these situations.
The following information is removed from the PFD
(and corresponding softkeys are disabled) when the aircraft experiences unusual attitudes:
• Traffic Annunciations
• AFCS Annunciations
• Flight director Command Bars
• Inset Map

11.4 STORMSCOPE OPERATION WITH
LOSS OF HEADING INPUT
If heading is lost, strikes and/or cells must be cleared
manually after the execution of each turn. This is to
ensure that the strike and/or cell positions are depicted
accurately in relation to the nose of the aircraft.
11.5 HAZARD DISPLAYS WITH LOSS OF
GPS POSITION
If GPS position is lost, or becomes invalid, selected
hazards being displayed on the Navigation Map Page
will be removed until GPS position is again established.
The icons in the lower right of the screen, indicating the
selected functions for display, will show an ‘X’, as shown
in Figure 11-3.

SECTION 11 – ABNORMAL
OPERATION
11.6 DEAD RECKONING
If at any time the G1000 detects an invalid GPS solution
or is unable to calculate a GPS position, the system will
automatically revert to Dead Reckoning (DR) mode. In DR
mode, the G1000 uses its last-known position combined
with continuously updated airspeed and heading data
(when available) to calculate and display the aircraft’s
current estimated position.
DR mode is indicated on the G1000 by the appearance
of the letters ‘DR’ superimposed in yellow over the ‘own
aircraft’ symbol as shown in Figure 11-4. In addition, ‘DR’
will be prominently displayed, also in yellow, on the HSI
slightly above and to the right of the aircraft symbol on the
CDI as shown in Figure 11-4. Lastly, but at the same time,
a ‘GPS NAV LOST’ alert message will appear on the PFD.
Normal navigation using GPS/WAAS source data
will resume automatically once a valid GPS solution is
restored.
It is important to note that estimated navigation
data supplied by the G1000 in DR mode may become
increasingly unreliable and must not be used as a sole
means of navigation. If while in DR mode airspeed and/or
heading data is also lost or not available, the DR function
may not be capable of accurately tracking your estimated
position and, consequently, the system may display a
path that is different than the actual movement of the
aircraft. Estimated position information displayed by
the G1000 through DR while there is no heading and/or
airspeed data available should not for navigation.
DR mode is inherently less accurate than the
standard GPS/WAAS mode due to the lack of satellite
measurements needed to determine a position. Changes
in wind speed and/or wind direction will compound the
relative inaccuracy of DR mode. Because of this degraded
accuracy, the crew must maintain position awareness using
other navigation equipment until GPS-derived position
data is restored.
CDI ‘DR’ Indication on PFD
Symbolic Aircraft
(Map pages and Inset Map)
Figure 11-4 Dead Reckoning Indications
As a result of operating in DR mode, all GPS-derived
data will be computed based upon an estimated position
and will be displayed as yellow text on the map to denote
degraded navigation source information. This data
includes the following:
• Navigation Status Box fields except Active Leg, TAS,
and DTK
• GPS Bearing Pointer
• Wind data and pointers in the Wind Data Box on
the PFD
• Track Bug
• All Bearing Pointer Distances
• Active Flight Plan distances, bearings, and ETE
values
Also, while the G1000 is in DR mode, the autopilot will
not couple to GPS, and both TAWS and Terrain Proximity
will be disabled. Additionally, the accuracy of all nearest
information (airports, airspaces, and waypoints) will be
questionable. Finally, airspace alerts will continue to
function, but with degraded accuracy.

& ALERTS
SECTION 12: ANNUNCIATIONS &
ALERTS
NOTE: The Cessna aircraft Pilot’s Operating
Handbook (POH) supersedes information found
in this document.
The G1000 Alerting System conveys alerts to the pilot
using a combination of the following items:
• Annunciation Window: The Annunciation
Window displays abbreviated annunciation text. Text
color is based on alert levels described later in the
Alert Levels Definitions section. The Annunciation
Window is located to the right of the Altitude and
Vertical Speed boxes on the display. All Cessna Nav
III annunciations can be displayed simultaneously
in the Annunciation Window. A white horizontal
line separates annunciations that are acknowledged
from annunciations that are not yet acknowledged.
Higher priority annunciations are displayed towards
the top of the window. Lower priority annunciations
are displayed towards the bottom of the window.
• Alerts Window: The Alerts Window displays alert
text messages. Up to 64 prioritized alert messages
can be displayed in the Alerts Window. Pressing
the ALERTS Softkey displays the Alerts Window.
Pressing the ALERTS Softkey a second time removes
the Alerts Window from the display. When the Alerts
Window is displayed, the pilot can use the large FMS
Knob to scroll through the alert message list.
• Softkey Annunciation: During certain alerts,
the ALERTS Softkey may appear as a flashing
annunciation to accompany an alert. The ALERTS
Softkey assumes a new label consistent with the
alert level (WARNING, CAUTION, or ADVISORY).
By pressing the softkey annunciation, the pilot
acknowledges awareness of the alert. The softkey
then returns to the previous ALERTS label. If alerts
are still present, the ALERTS label will be displayed
in inverse video (white background with black text).
The pilot can press the ALERTS Softkey a second
time to view alert text messages.
• System Annunciations: Typically, a large red ‘X’
appears in windows when a failure is detected in the
LRU providing the information to the window. See
the G1000 System Annunciations section for more
information.
• Audio Alerting System: The G1000 system issues
audio alert tones when specific system conditions are
met. See the Alert Levels Definitions section for more
information.

12.1 ALERT LEVEL DEFINITIONS
The G1000 Alerting System, as installed in Cessna Nav
III aircraft, uses three alert levels.
• WARNING: This level of alert requires immediate
pilot attention. A warning alert is annunciated in
the Annunciation Window and is accompanied
by a continuous aural tone. Text appearing in the
Annunciation Window is RED. A warning alert is
also accompanied by a flashing WARNING Softkey
annunciation, as shown in Figure 12-2. Pressing
the WARNING Softkey acknowledges the presence
of the warning alert and stops the aural tone, if
applicable.
• CAUTION: This level of alert indicates the
existence of abnormal conditions on the aircraft
that may require pilot intervention. A caution alert
is annunciated in the Annunciation Window and is
accompanied by a single aural tone. Text appearing
in the Annunciation Window is YELLOW. A caution
alert is also accompanied by a flashing CAUTION
Softkey annunciation, as shown in Figure 12-3.
Pressing the CAUTION Softkey acknowledges the
presence of the caution alert.

• MESSAGE ADVISORY: This level of alert provides
general information to the pilot. A message
advisory alert does not issue annunciations in the
Annunciation Window. Instead, message advisory
alerts only issue a flashing ADVISORY Softkey
annunciation, as shown in Figure 12-4. Pressing
the ADVISORY Softkey acknowledges the presence
of the message advisory alert and displays the alert
text message in the Alerts Window.
