WARNINGS, CAUTIONS, AND 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WARNING: Do not use outdated database information.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 Pilots using any outdated database do so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.
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.

WARNINGS, CAUTIONS, AND NOTES
WARNING: For safety reasons, G1000 operational procedures must be learned on the ground.
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: 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.
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.

SYSTEM OVERVIEW
SECTION 1 SYSTEM OVERVIEW
1.1 SYSTEM DESCRIPTION
This section is designed to provide an overview of the G1000 Integrated Flight Deck as installed in Cessna
Nav III aircraft, which include the Cessna 172R, the Cessna 172S, the normally aspirated Cessna 182 (182), the
turbocharged Cessna 182 (T182), the normally aspirated Cessna 206 (206), and the turbocharged Cessna 206
(T206).
The G1000 system is an integrated flight control system that presents flight instrumentation, position, navigation,
communication, and identification information to the pilot through large-format displays. The system consists of
the following Line Replaceable Units (LRUs):
• GDU 1040/1044B Primary Flight Display (PFD)
• GMU 44 Magnetometer
• GDU 1040/1044B Multi Function Display (MFD)
• GIA 63/63W Integrated Avionics Unit (IAU)
• GMA 1347 Audio System with Integrated Marker
Beacon Receiver
• GDC 74A Air Data Computer (ADC)
• GTX 33 Mode S Transponder
• GEA 71 Engine/Airframe Unit
• GDL 69A Satellite Data Link Receiver
• GRS 77 Attitude and Heading Reference System
(AHRS)
• GSA 81 AFCS Servos
• GSM 85 Servo Mounts
A top-level G1000 system block diagram is shown in Figure 1-1. See Figure 1-2 for optional/additional
equipment.
NOTE: Refer to the AFCS section for details on the GFC 700 AFCS.
In Cessna 182 and 206 Nav III aircraft, the GFC 700 Automated Flight Control System (AFCS) provides the
flight director (FD) and autopilot (AP) functions of the G1000 system.

SYSTEM OVERVIEW
1.2 LINE REPLACEABLE UNITS (LRU)
• GDU 1040/1044B – The GDU 1040 is used in the Cessna 172 and features a 10.4-inch LCD display with 1024
x 768 resolution. The left display is configured as a PFD and the right display is configured as an MFD. Both
GDU 1040s link and display all functions of the G1000 system during flight. The displays communicate with
each other through a High-Speed Data Bus (HSDB) Ethernet connection. Each display is also paired via an
Ethernet connection with a GIA 63 or 63W Integrated Avionics Unit. The Cessna 182 and 206 use the GDU
1044B, which employs the same features as the GDU 1040 with the additional controls for the Automatic Flight
Control System (AFCS)
• GIA 63/63W (2) – Functions as the main communication hub, linking all LRUs with the PFD. Each GIA 63/
63W contains a GPS receiver, VHF COM/NAV/GS receivers, a flight director (FD) and system integration
microprocessors. The GIA 63W contains a GPS WAAS receiver. Each GIA is paired with a respective GDU
1040/1044B display through Ethernet. The GIAs are not paired together and do not communicate with each
other directly.
• GDC 74A (1) – Processes data from the pitot/static system as well as the OAT probe. This unit provides
pressure altitude, airspeed, vertical speed and OAT information to the G1000 system, and it communicates with
the GIA 63/63W, GDU 1040/1044B, and GRS 77, using an ARINC 429 digital interface. The GDC 74A also
interfaces directly with the GTP 59.

190-00498-01 Rev. A
SYSTEM OVERVIEW
• GEA 71 (1) – Receives and processes signals from the engine and airframe sensors. This unit communicates
with both GIA 63/63Ws using an RS-485 digital interface.
• GRS 77 (1) – Provides aircraft attitude and heading information via ARINC 429 to both the GDU 1040/1044B
and the GIA 63/63W. The GRS 77 contains advanced sensors (including accelerometers and rate sensors)
and interfaces with the on-side GMU 44 to obtain magnetic field information, with the GDC 74A to obtain
air data, and with both GIAs to obtain GPS information. AHRS modes of operation are discussed later in this
document.
• GMU 44 (1) – Measures local magnetic field. Data is sent to the GRS 77 for processing to determine aircraft
magnetic heading. This unit receives power directly from the GRS 77 and communicates with the GRS 77,
using an RS-485 digital interface.
• GMA 1347 – The GMA 1347 Audio Panel integrates NAV/COM digital audio, intercom system and marker
beacon controls. The GMA 1347 also controls manual display reversionary mode (red DISPLAY BACKUP
button) and is installed between the MFD and the PFD. The GMA 1347 communicates with both GIA 63/
63Ws using an RS-232 digital interface.
190-00498-01 Rev. A

SYSTEM OVERVIEW
• GTX 33 (1) – The GTX 33 is a solid-state, Mode-S transponder that provides Modes A, C and S operation. The
GTX 33 is controlled through the PFD and communicates with both GIA 63/63Ws through an RS-232 digital
interface.
• GDL 69A (1) – A satellite radio receiver that provides real-time weather information to the G1000 MFD (and,
indirectly, to the inset map of the PFD) as well as digital audio entertainment. The GDL 69A communicates
with the MFD via HSDB connection. A subscription to the XM Satellite Radio service is required to enable the
GDL 69A capability.
• GSA 81 (3), and GSM 85 (3) – The GSA 81 servos are used for the automatic control of roll, pitch, and pitch
trim. These units interface with each GIA 63/63W.
The GSM 85 servo mount is responsible for transferring the output torque of the GSA 81 servo actuator to the
mechanical flight-control surface linkage.

SYSTEM OVERVIEW
1.5 SYSTEM POWER-UP
NOTE: See the Aircraft Flight Manual (AFM) for specific procedures concerning avionics power application
and emergency power supply operation.
NOTE: Refer to Appendix A for system-specific annunciations and alerts.
The G1000 System is integrated with the aircraft electrical system and receives power directly from electrical
busses. The G1000 PFD, MFD, and supporting sub-systems include both power-on and continuous built-in test
features that exercise the processor, RAM, ROM, external inputs, and outputs to provide safe operation.
During system initialization, test annunciations are displayed, as shown in Figure 1-6. All system annunciations
should disappear typically within the first minute of power-up. Upon power-up, key annunciator lights also
become momentarily illuminated on the Audio Panel.
On the PFD, the AHRS begins to initialize and displays “AHRS ALIGN: Keep Wings Level”. The AHRS should
display valid attitude and heading fields typically within the first minute of power-up. The AHRS can align itself
both while taxiing and during level flight.
When the MFD powers up, the splash screen (Figure 1-7) displays the following information:
• System version
• Copyright
• Land database name and version
• Obstacle database name and version
• Terrain database name and version
• Aviation database name, version, and effective dates
• SafeTaxi database version and effective dates
• Chartview or FliteCharts database version and
effective dates
Current database information includes valid operating dates, cycle number, and database type. When this
information has been reviewed for currency (to ensure that no databases have expired), the pilot is prompted to
continue.
Pressing the ENT Key (or right-most softkey) acknowledges this information, and the Navigation Map Page is
displayed upon pressing the key a second time. When the system has acquired a sufficient number of satellites to
determine a position, the aircraft’s current position is shown on the Navigation Map Page.

SYSTEM OVERVIEW
1.6 SYSTEM OPERATION
NOTE: In normal operating mode, backlighting can only be adjusted from the PFD. In reversionary mode, it
can be adjusted from the remaining display.
The displays are connected together via a single Ethernet bus for high-speed communication. Each IAU is
connected to a single display, as shown in Figure 1-1. This allows the units to share information, enabling true system
integration.. This section discusses normal and reversionary G1000 display operation, as well as the various AHRS
modes and G1000 System Annunciations.
NORMAL DISPLAY OPERATION
In normal operating mode, the PFD presents graphical flight instrumentation (attitude, heading, airspeed,
altitude, vertical speed), replacing the traditional flight instrument cluster (see the Flight Instruments Section
for more information).
The MFD normally displays a full-color moving map with navigation information (see the GPS Navigation
Section), while the left portion of the MFD is dedicated to the Engine Indication System (EIS; see the EIS
Section).
Both displays offer control for COM and NAV frequency selection.
Figure 1-8 Normal Mode
REVERSIONARY DISPLAY OPERATION
NOTE: The G1000 System alerts the pilot when backup paths are utilized by the LRUs. Refer to Appendix A
for further information regarding system-specific alerts.
In the event of a display failure, the G1000 System automatically switches to reversionary (backup) mode. In
reversionary mode, all important flight information is presented on the remaining display in the same format
as in normal operating mode.
If a display fails, the appropriate IAU Ethernet interface to the display is cut off. Thus, the IAU can no longer
communicate with the remaining display (refer to Figure 1-1), and the NAV and COM functions provided to
the failed display by the IAU are flagged as invalid on the remaining display. The system reverts to backup
paths for the AHRS, ADC, Engine/Airframe Unit, and Transponder, as required. The change to backup paths is
completely automated for all LRUs and no pilot action is required.

AHRS OPERATION
NOTE: Refer to Appendix A for specific AHRS alert information.
NOTE: Aggressive maneuvering while AHRS is not operating normally may degrade AHRS accuracy.
The Attitude and Heading Reference System (AHRS) performs attitude, heading, and vertical acceleration
calculations for the G1000 System, utilizing GPS, magnetometer, and air data in addition to information
from its internal sensors. Attitude and heading information are updated on the PFD while the AHRS receives
appropriate combinations of information from the external sensor inputs.
Loss of GPS, magnetometer, or air data inputs is communicated to the pilot by message advisory alerts. Any
failure of the internal AHRS inertial sensors results in loss of attitude and heading information (indicated by red
‘X’ flags over the corresponding flight instruments).

GPS INPUT FAILURE
NOTE: In-flight initialization of AHRS, when operating without any valid source of GPS data and at true
air speed values greater than approximately 200 knots, is not guaranteed. Under these rare conditions, it
is possible for in-flight AHRS initialization to take an indefinite amount of time which would result in an
extended period of time where valid AHRS outputs are unavailable.
Two GPS inputs are provided to the AHRS. If GPS information from one of the inputs fails, the AHRS uses
the remaining GPS input and an alert message is issued to inform the pilot. If both GPS inputs fail, the AHRS
can continue to provide attitude and heading information to the PFD as long as magnetometer and airspeed
data are available and valid.
MAGNETOMETER FAILURE
If the magnetometer input fails, the AHRS continues to output valid attitude information; however, the
heading output on the PFD is flagged as invalid with a red ‘X’.
AIR DATA INPUT FAILURE
Failure of the air data input has no affect on the AHRS output while AHRS is receiving valid GPS
information. Invalid/unavailable airspeed data in addition to GPS failure results in loss of all attitude and
heading information.

G1000 SYSTEM ANNUNCIATIONS
NOTE: For a detailed description of all annunciations and alerts, refer to Appendix A. Refer to the Pilot’s
Operating Handbook (POH) for additional information regarding pilot responses to these annunciations.
When an LRU or an LRU function fails, a large red “X” is typically displayed on windows associated with
the failed data (Figure 1-12 displays all possible flags and responsible LRUs). Upon G1000 power-up, certain
windows remain invalid as equipment begins to initialize. All windows should be operational within one
minute of power-up. If any window remains flagged, the G1000 system should be serviced by a Garminauthorized repair facility.

Satellites currently in view are shown at their respective positions on a sky view diagram. The sky view is
always in a north-up orientation, with the outer circle representing the horizon, the inner circle representing
45° above the horizon, and the center point showing the position directly overhead.
Each satellite is represented by an oval containing the Pseudo-random noise (PRN) number (i.e., satellite
identification number). Satellites whose signals are currently being used are represented by solid ovals.
1-18
Garmin G1000 Pilot’s Guide for Cessna Nav III
190-00498-01 Rev. A
SYSTEM OVERVIEW
• Satellite signal information status
The accuracy of the aircraft’s GPS fix is calculated using Estimated Position Uncertainty (EPU), Dilution
of Precision (DOP), and horizontal and vertical figures of merit (HFOM and VFOM). EPU is the radius of a
circle centered on an estimated horizontal position in which actual position has 95% probability of laying.
EPU is a statistical error indication and not an actual error measurement.
DOP measures satellite geometry quality (i.e., number of satellites received and where they are relative to
each other) on a range from 0.0 to 9.9, with lower numbers denoting better accuracy. HFOM and VFOM,
measures of horizontal and vertical position uncertainty, are the current 95% confidence horizontal and
vertical accuracy values reported by the GPS receiver.
The current calculated GPS position, time, altitude, ground speed, and track for the aircraft are displayed
below the satellite signal accuracy measurements.
• GPS receiver status
The GPS solution type (ACQUIRING, 2D NAV, 2D DIFF NAV, 3D NAV, 3D DIFF NAV) for the active
GPS receiver (GPS1 or GPS2) is shown in the upper right of the GPS Status Page. When the receiver is
in the process of acquiring enough satellite signals for navigation, the receiver uses satellite orbital data
(collected continuously from the satellites) and last known position to determine the satellites that should be
in view. ACQUIRING is indicated as the solution until a sufficient number of satellites have been acquired
for computing a solution.
When the receiver is in the process of acquiring a 3D navigational GPS solution, 3D NAV is indicated as the
solution until the 3D differential fix has finished acquisition. SBAS (Satellite-Based Augmentation System)
will indicate INACTIVE. When acquisition is complete, the solution status will indicate 3D DIFF NAV and
SBAS will indicate ACTIVE.
• RAIM (Receiver Autonomous Integrity Monitoring) Prediction (RAIM Softkey is selected on WAAS enabled
systems)(Default on non-WAAS systems)
In G1000 systems with WAAS enabled, performing a RAIM prediction will not be necessary in most cases.
However, in some cases, the selected approach may be outside the WAAS coverage area and it may be
necessary to perform a RAIM prediction for the intended approach.
Receiver Autonomous Integrity Monitoring (RAIM) is a GPS receiver function that performs a consistency
check on all tracked satellites. RAIM ensures that the available satellite geometry allows the receiver to
calculate a position within a specified RAIM protection limit (2.0 nautical miles for oceanic and enroute, 1.0
nm for terminal, and 0.3 nm for non-precision approaches). During oceanic, enroute, and terminal phases of
flight, RAIM is available nearly 100% of the time.
The RAIM prediction function also indicates whether RAIM is available at a specified date and time. RAIM
computations predict satellite coverage within ±15 min of the specified arrival date and time.
Because of the tighter protection limit on approaches, there may be times when RAIM is not available. The
G1000 automatically monitors RAIM and warns with an alert message when it is not available. If RAIM is not
predicted to be available for the final approach course, the approach does not become active, as indicated by
the messages “Approach is not active” and “RAIM not available from FAF to MAP”. If RAIM is not available
when crossing the FAF, the missed approach procedure must be flown.

SYSTEM OVERVIEW
• GPS Satellite Signal Strengths
The GPS Status Page can be helpful in troubleshooting weak (or missing) signal levels due to poor satellite
coverage or installation problems. As the GPS receiver locks onto satellites, a signal strength bar is displayed
for each satellite in view, with the appropriate satellite PRN number (01-32 or 120-138 for WAAS) below each
bar. The progress of satellite acquisition is shown in three stages, as indicated by signal bar appearance:
- No signal strength bar—Receiver is looking for the indicated satellite
- Hollow signal strength bar—Receiver has found the satellite and is collecting data
- Solid signal strength bar—Receiver has collected the necessary data and the satellite signal can be used
- Checkered signal strength bar—Receiver has excluded the satellite (Fault Detection and Exclusion)
- “D” indication—Denotes the satellite is being used as part of the differential computations
Each satellite has a 30-second data transmission that must be collected (signal strength bar is hollow) before
the satellite may be used for navigation (signal strength bar becomes solid).
SOFTKEY FUNCTION
The softkeys are located along the bottoms of the displays. The softkeys shown depend on the softkey level
or page being displayed. The bezel keys below the softkeys can be used to select the appropriate softkey. When
a softkey is selected, its color changes to black text on gray background and remains this way until it is turned
off, at which time it reverts to white text on black background.

GPS CDI
The GPS CDI Box on the System Setup Page allows the pilot to define the range for the on-screen course
deviation indicator (CDI). The range values represent full range deflection for the CDI to either side. The
default setting is ‘AUTO’. At this setting, leaving the departure airport the CDI range is set to 1.0 nm and
gradually ramps up to 2.0 nm beyond 30 nm from the departure airport. The CDI range is set to 2.0
nautical miles during the en route phase of flight. Within 31 nm of the destination airport, the CDI range
gradually ramps down to 1.0 nm (terminal area). During approach operations, the CDI range ramps down
even further to 0.3 nm, or less using angular scaling. This transition normally occurs within 2.0 nm of the
final approach fix (FAF) and the desired track is within 45 degrees of the IAF to FAF segment.
190-00498-01 Rev. A
Garmin G1000 Pilot’s Guide for Cessna Nav III
1-35
SYSTEM OVERVIEW
If a lower CDI range setting is selected (i.e., 1.0 or 0.3 nm), the higher range settings are not selected
during any phase of flight. For example, if 1.0 nm is selected, the G1000 uses this for en route and terminal
phases and ramps down to the proper scaling during an approach.
The GPS CDI Box on the System Setup Page displays the following:
• Selected CDI range (auto, 2 nm, 1 nm, 0.3 nm)
• Current system CDI range (2 nm, 1 nm, 0.3 nm)

GLIDESLOPE, GLIDEPATH, AND VERTICAL DEVIATION INDICATORS
NOTE: The Glidepath Indicator is only shown for aircraft with GIA 63W Integrated Avionics Units when
WAAS is available.
NOTE: The Vertical Deviation Indicator (VDI) turns yellow when operating in Dead Reckoning Mode.
The Glideslope Indicator (Figure 2-12) appears to the left of the Altimeter whenever an ILS is tuned in the
active NAV field and selected on the Audio Panel. A green diamond acts as the Glideslope Indicator, like a
glideslope needle on a conventional indicator. If a localizer frequency is tuned and there is no glideslope, “NO
GS” is annunciated.
The glidepath is analogous to the glideslope for GPS approaches supporting WAAS vertical guidance (LNAV+V,
L/VNAV, LPV) and is generated by the system to reduce pilot workload during approach. When an approach
of this type is loaded into the flight plan and GPS is the selected navigation source, the Glidepath Indicator
appears as a magenta diamond. If the approach type downgrades past the final approach fix (FAF), “NO GP”
is annunciated.
The Vertical Deviation Indicator (VDI; Figure 2-13) uses a magenta chevron to indicate the vertical deviation
when Vertical Navigation (VNAV) is being used; the VDI appears in conjunction with the “one minute to Top of
Descent (TOD)” alert. See the GPS Navigation and AFCS sections for details on VNAV features.

HORIZONTAL SITUATION INDICATOR (HSI)
The Horizontal Situation Indicator (HSI) displays a rotating compass card in a heading-up orientation. Letters
indicate the cardinal points and numeric labels occur every 30˚. Major tick marks are at 10˚ intervals and minor
tick marks at 5˚ intervals. The HSI presents heading, turn rate, course deviation, bearing, and navigation source
information and is available in two formats (360˚ compass rose and 140˚ arc).
Changing the HSI display format:
1) Press the PFD Softkey
2) Press the 360 HSI or ARC HSI Softkey.
The 360˚ HSI (Figure 2-14) contains a Course Deviation Indicator (CDI), with a Course Pointer, To/From
Indicator, and a sliding deviation bar and scale. The course pointer is a single line arrow (GPS, VOR1, and
LOC1) or a double line arrow (VOR2 and LOC2) which points in the direction of the set course. The To/From
arrow rotates with the course pointer and is displayed when the active NAVAID is received.

The system automatically switches from GPS to LOC navigation source (ILS CDI capture) and changes the
CDI scaling accordingly when all of the following occur:
• A localizer or ILS approach has been loaded into the active flight plan
• The final approach fix (FAF) is the active leg, the FAF is less than 15 nm away, and the aircraft is moving
toward the FAF
• A valid localizer frequency has been tuned
• The GPS CDI deviation is less than 1.2 times full-scale deflection
GPS steering guidance is still provided after the HSI automatically switches to LOC until LOC capture, up
to the Final Approach Fix (FAF) for an ILS approach, or until GPS information becomes invalid. Activating
a Vector-to-Final (VTF) approach (see the GPS Navigation Section) also causes the HSI to switch to LOC
navigation source; GPS steering guidance is not provided after this switch.

OBS MODE
Enabling Omni-bearing Selector (OBS) Mode (with the OBS Softkey) suspends the automatic sequencing
of waypoints in a GPS flight plan (GPS must be the selected navigation source), but retains the current
“active-to” waypoint as the navigation reference even after passing the waypoint. ‘OBS’ is annunciated to
the lower right of the aircraft symbol when OBS Mode is selected (see Figure 2-24). When OBS is disabled
(the OBS Softkey is pressed again), the GPS returns to normal operation, with automatic sequencing of
waypoints. OBS mode also allows a desired course to/from a waypoint to be set (with a CRS Knob);
pressing the CRS Knob re-centers the CDI and returns the course pointer to the waypoint bearing.

COURSE DEVIATION INDICATOR (CDI)
NOTE: The CDI is removed from the display when operating in Dead Reckoning Mode.
The Course Deviation Indicator (CDI) moves left or right from the course pointer along a lateral deviation
scale to display aircraft position relative to the course. If the course deviation data is not valid, the CDI is not
displayed. The CDI has the same angular limits as a mechanical CDI when coupled to a VOR or localizer
(LOC). When coupled to GPS, the full scale limits for the CDI are defined by a GPS-derived distance. If the
CDI exceeds the maximum deviation on the scale (two dots) while coupled to GPS, the crosstrack error (XTK)
is displayed below the aircraft symbol.

In GPS mode, the flight plan legs are sequenced automatically and annunciations appear on the HSI for
the flight phase. If the current leg in the flight plan is a heading leg, ‘HDG LEG’ is annunciated in magenta
beneath the aircraft symbol.
The current GPS CDI scale setting is displayed as ‘System CDI’ on the AUX - System Setup Page and the
scale setting may also be changed (2.0 nm, 1.0 nm, 0.3 nm, or Auto) from this page (Figure 2-26). If the
selected scaling is smaller than the automatic setting for enroute and terminal phases, the selected setting may
be displayed rather than the flight phase annunciation. Receiver Autonomous Integrity Monitoring (RAIM)
protection limits follow the selected CDI scale and corresponding flight phases.
When set to ‘Auto’ (default), the CDI scale automatically adjusts to the desired limits based upon the
current phase of flight:
• Thirty nautical miles from the departure airport (or at the last departure waypoint if farther than 30 nm
from the departure airport), the system automatically selects the enroute phase of flight and changes the
CDI scaling to 2.0 nm.
• If after completing the departure procedure the nearest airport is more than 200 nm away from the aircraft
and the approach procedure has not yet commenced, the CDI is scaled for oceanic flight (2.0 nm).
• Within 31 nm of the destination airport (terminal area), the CDI scale gradually ramps down from 2.0 nm
to 1.0 nm over a distance of 1.0 nm; if a transition back to enroute flight occurs, the CDI scale increases
back to 2.0 in the same manner.
2-16
Garmin G1000 Pilot’s Guide for Cessna Nav III
190-00498-01 Rev. A
FLIGHT INSTRUMENTS
• During approach operations, the CDI scale ramps down even further (see Table 2-2). This transition
normally occurs within 2.0 nm of the final approach fix (FAF). The ground track must be within 45˚ of the
flight plan leg to the FAF to enter approach mode.
• For a missed approach, the CDI scale changes to 0.3 nm if the aircraft has not yet reached the turn initiation
point and the legs of the missed approach (including the active leg) are aligned to within 3˚ of the final
approach segment course.

5) To remove the window, press the CLR Key or the TMR/REF Softkey.
Figure 2-40 Barometric Minimum Descent Altitude
The following visual annunciations alert the pilot when approaching the MDA (Figure 2-41):
• When the aircraft altitude descends to within 2500 feet of the MDA setting, the Barometric Minimum Window
appears with the altitude in light blue text. The bug appears on the tape in light blue once in range.
• When the aircraft passes through 100 feet of the MDA, the bug and text turn white.
• Once the aircraft descends past the MDA, the bug and text turn yellow and the aural alert, “Minimums
Minimums”, is generated.
Alerting is inhibited while the aircraft is on the ground and until the aircraft reaches 150 ft above the MDA.
If the aircraft proceeds to climb after having reached the MDA, once it reaches 50 ft above the MDA, alerting is
disabled.

3.2 LEAN DISPLAY
NOTE: The pilot should follow the engine manufacturer’s recommended leaning procedures in the Pilot’s
Operating Handbook (POH).
The Lean Display is accessed by pressing the ENGINE Softkey followed by the LEAN Softkey and provides
information for performing engine leaning. The engine gauge(s) and Fuel Quantity Indicator remain on the Lean
Display and fuel flow is listed as a numeric readout. Exhaust gas (EGT) and cylinder head (CHT) temperatures for
all cylinders are displayed graphically with numeric readouts for the selected cylinder. For turbocharged aircraft,
the Turbine Inlet Temperature (TIT) Indicator is shown above the EGT Bar Graph.
Accessing the EIS Lean Display:
1) Press the ENGINE Softkey.
2) Press the LEAN Softkey.
3) To return to the default Engine Display, press the ENGINE or BACK Softkey.
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.
Monitoring the desired cylinder’s EGT and CHT:
From the Lean Display, press the CYL SLCT Softkey to cycle through each cylinder and view its EGT and CHT.
The selected cylinder is shown in light blue.
The ASSIST Softkey aids in the leaning process by identifying the peak of the first cylinder whose temperature
falls. This cylinder’s bar on the EGT and CHT bar graphs is highlighted in cyan as the selected cylinder. If the
temperature of the peaked cylinder exceeds the peak value, the peak value is not updated. Monitoring of the
cylinder continues until the ASSIST Softkey is pressed again which disables lean assist, and removes the peak
block from the bar graph and the temperature deviation from peak (∆PEAK). The system then returns to seeking
the hottest cylinder.

AUDIO PANEL AND CNS
SECTION 4 AUDIO PANEL AND CNS
4.1 OVERVIEW
The Communication/Navigation/Surveillance (CNS) system includes the Audio Panel, communication radios,
navigation radios, and Mode S transponder. The System Overview section provides a block diagram description
of the Audio Panel and CNS system interconnection.
CNS operation in Cessna Nav III aircraft is performed by the following Line Replaceable Units (LRUs):
• GMA 1347 Audio Panel
• GDU 1040/1044B Primary Flight Display (PFD) and
GDU 1040/1044B Multi Function Display (MFD)
• GTX 33 Mode S Transponder
• GIA 63/63W Integrated Avionics Units (2)
The PFD/MFD controls are used to tune the communication transceivers and navigation radios.
The Audio Panel provides the traditional audio selector functions of microphone and receiver audio selection.
The Audio Panel includes an intercom system (ICS) between the pilot, copilot, and passengers, a marker beacon
receiver, and a COM clearance recorder. Ambient noise from the aircraft radios is reduced by a feature called
Master Avionics Squelch (MASQ). When no audio is detected, MASQ processing further reduces the amount of
background noise from the radios.
The Mode S transponder is controlled with softkeys located on the Primary Flight Display (PFD) at the lower
portion of the screen. The Transponder Data Box is located to the left of the System Time Box. The data box
displays a four-digit code field, a mode field, and a reply status indicator (Figure 4-1).

POWER-UP AND FAIL-SAFE OPERATION
POWER-UP
The Audio Panel performs a self-test during power-up. During the self-test all Audio Panel annunciator
lights illuminate for approximately two seconds. Once the self-test is completed, most of the settings are
restored to those in use before the unit was last turned off.
FAIL-SAFE OPERATION
If there is a failure of the Audio Panel, a fail-safe circuit connects the pilot’s headset and microphone directly
to the COM1 transceiver. Audio is not available on the speaker.
MONO/STEREO HEADSETS
Stereo headsets are recommended for use with the G1000.
Using a monaural headset in a stereo jack shorts the right headset channel output to ground. While this does
not damage the Audio Panel, a person listening on a monaural headset hears only the left channel in both ears.
If a monaural headset is used at one of the passenger positions, any other passenger using a stereo headset hears
audio in the left ear only.
SPEAKER
All of the radios can be heard over the cabin speaker. Pressing the SPKR Key selects and deselects the cabin
speaker. Speaker audio is muted when the PTT is pressed. Certain aural alerts and warnings (autopilot, traffic,
altitude) are always heard on the speaker, even when the speaker is not selected.
The speaker volume is adjustable within a nominal range. Contact a Garmin-authorized service center for
volume adjustment.

AUDIO PANEL AND CNS
ENTERTAINMENT INPUTS
NOTE: MUSIC 1 and MUSIC 2 inputs cannot be completely turned off. Audio level for MUSIC 1 and MUSIC 2
can be adjusted by a Garmin-authorized service center.
The Audio Panel provides two stereo auxiliary entertainment inputs: MUSIC 1 and MUSIC 2. These inputs
are compatible with popular portable entertainment devices such as MP3 and CD players. Two 3.5 mm
stereo phone jacks are installed in convenient locations for audio connection. The headphone outputs of the
entertainment devices are plugged into the MUSIC 1 or MUSIC 2 jacks.
The current ICS state of isolation affects the distribution of the entertainment input MUSIC 1. (See
Table 4-1).
MUSIC 1
MUSIC 1 can be heard by the pilot and copilot when both the PILOT and the COPLT Annunciators are
extinguished. MUSIC 1 can also be heard by the pilot when the COPLT Annunciator is illuminated and by
the copilot when the PILOT Annunciator is illuminated.
MUSIC 1 MUTING
MUSIC 1 muting occurs when aircraft radio or marker beacon activity is heard. MUSIC 1 is always soft
muted when an interruption occurs from an aircraft radio. Soft muting is the gradual return of MUSIC 1 to
its original volume level. The time required for MUSIC 1 volume to return to normal is between one-half
and four seconds.
MUSIC 1 MUTING ENABLE/DISABLE
Pressing and holding the MKR/MUTE Key for three seconds switches MUSIC 1 muting on and off. When
switching, either one or two beeps are heard; one beep indicates that music muting is enabled, two beeps
indicate music muting is disabled. MUSIC 1 muting is reset (enabled) during power up.
MUSIC 2
MUSIC 2 can be heard only by the passengers and is never muted.
DATA LINK RECEIVER XM RADIO SYSTEM
XM Radio Audio from the Data Link Receiver may be heard by the pilot and passengers simultaneously
(optional: requires subscription to XM Audio Service). Refer to the Additional Features Section for more
details on the Data Link Receiver.
Connecting a stereo input to either MUSIC 1 or MUSIC 2 jacks removes the Data Link Receiver Audio from
that input. For example, if passengers prefer their own music while the pilot listens to the Data Link Receiver,
the entertainment audio should be connected to the MUSIC 2 jack.

4.6 PREFLIGHT PROCEDURE FOR THE GMA 1347 AUDIO PANEL
NOTE: If the pilot and/or copilot are using headsets that have a high/low switch or volume control knob,
verify that the switch is in the high position and the volume control on the headsets are at max volume
setting. On single pilot flights verify that all other headsets are not connected to avoid excess noise in the
audio system.
NOTE: When the MAN SQ Key is pressed the ICS squelch can be set manually by the pilot and copilot. If
manual squelch is set to full open (SQ annunciated and the knobs turned counterclockwise) background
noise is heard in the ICS system as well as during COM transmissions.
After powering up the G1000 System, the following steps will aid in maximizing the use of the Audio Panel as
well as prevent pilot and copilot induced issues. These preflight procedures should be performed each time a
pilot boards the aircraft to insure awareness of all audio levels in the Audio Panel and radios.

Setting the Audio Panel during preflight:
1) Verify that the PILOT and COPLT Annunciators are extinguished.
2) Verify that the MAN SQ Annunciator is extinguished.
3) Turn the PILOT/PASS Knobs clockwise two full turns. This will set the headset audio level to max volume (least
amount of attenuation).
4) Adjust radio volume levels (COM, NAV, etc.) to a suitable level.
5) Adjust the PILOT/PASS Knob volume to the desired intercom level.
Once this procedure has been completed, the pilot and copilot can change settings to their liking, keeping in
mind the notes above.

5.2 NAVIGATION MAP (MFD)
WARNING: The basemap (land and water data) must not be used for navigation, rather only for situational
awareness. Any basemap indication should be compared with other navigation sources.
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 5-1. 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 5-2. 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.

GPS NAVIGATION
Figure 5-2 Symbolic aircraft on the Navigation Map Page and
the Inset Map
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.

and class of airspace, the ceiling in feet expressed in Mean Seal Level (MSL), and the floor in feet MSL.
Panning the map:
1) Push in the JOYSTICK to display the map arrow.
2) Move the JOYSTICK in the general direction of the desired destination to place the arrow at the destination
location. When the arrow is placed on an object, the name of the object is highlighted (even if the name was
not originally displayed on the map). This feature applies to everything displayed on the map except route lines.
When any map feature or object is selected on the map display, features or objects are displayed in the box located
at the top of the display. From here, the pilot can designate the waypoint as the direct-to destination. When the
arrow crosses an airspace boundary, the boundary is highlighted and airspace information is displayed at the
top of the display.
3) Push in the JOYSTICK to remove the arrow and return to the present position.

GENERAL NOTES ON AIRSPACE ALERTS
Once an airspace alert has been selected, associated information concerning the specific airspace is
provided. The information includes Airspace Name, Status, and Time to Entry. The status and time to entry
(if applicable) are based on the following conditions:
• If the projected course will take the aircraft inside an airspace within the next ten minutes, the status field
shows the airspace as ‘Ahead’.
• If the aircraft is within two nautical miles of an airspace and the current course will take the aircraft inside,
the status field shows the airspace as ‘Ahead < 2 nm’.
• If the aircraft is within two nautical miles of an airspace and the current course will not take the aircraft
inside, the status field shows ‘Within 2 nm’.
• If the aircraft has entered an airspace, the status field shows ‘Inside’.
The airspace alerts are based on three-dimensional data (latitude, longitude, and altitude) to avoid nuisance
alerts. The alert boundaries for controlled airspace are also sectored to provide complete information on any
nearby airspace. Once the described conditions exists, the status and time of entry is shown if the airspace alert
messages are enabled on the System Setup Page (Auxiliary Page Group; see the System Overview Section).
At most three airspace alerts are displayed at any given time. The user can change the airspace alerts that
are currently visible. For each airspace alert the name of the airspace, the proximity status (Inside, Ahead <
2nm, Ahead, Within 2nm), and the time until the current path of the aircraft will intercept the airspace (only
when the airspace is Ahead, or Ahead < 2nm, otherwise “__:__:__” is used) is displayed. If there are more
than three airspace alerts they are displayed in a scrollable list box with only three visible at one time.

VERTICAL NAVIGATION
NOTE: Refer to the Appendices for VNAV Flight Planning definitions, abbreviations, and acronyms.
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.
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.
To help interpret the meanings of how the altitudes are presented, keep the following points in mind:
• When the altitude is displayed in light blue, the system is using that altitude to determine vertical speed
and deviation guidance.
• When the altitude is displayed in white, it is not being used by the system 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.
Refer to Figure 5-71 and Table 5-3 for more detail regarding the significance of text size and color.

ALTITUDE CONSTRAINTS
The G1000 provides a means to enter altitude constraints associated with waypoints in the active flight
plan so long as the waypoint is not the final approach fix, a waypoint after the FAF, or part of an unsupported
lateral leg type.
Altitude constraints are displayed and entered in mean sea level (MSL) values to the nearest hundreth. An
altitude constraint in above ground level (AGL) format is supported for airports. To convert the value to AGL,
turn the FMS Knob when MSL is highlighted and press the ENT Key. When a database altitude restriction is
displayed, the G1000 allows user entry of a different altitude when creating a waypoint, effectively overriding
the database restriction (only before the FAF). The G1000 allows activation of a displayed database altitude
restriction by highlighting the database constraint and selecting the ENT Key. When a database altitude
restriction of type “AT or ABOVE” or “AT or BELOW” is activated, the G1000 uses the “AT” portion of the
restriction to define the vertical profile.
The G1000 annunciates all constraints that cannot be used to calculate vertical guidance by displaying the
value in halftone, light blue text. The following conditions constitute an invalid altitude constraint:
• Meeting the constraint requires the aircraft to climb
• Meeting the constraint requires the maximum flight path angle to be exceeded
• Meeting the constraint requires the maximum vertical speed to be exceeded
• The altitude constraint results in a TOD behind the aircraft present position
• The constraint is within a leg type for which altitude constraints are not supported
• The pilot is attempting to add an altitude constraint to the FAF or a waypoint past the FAF of an approach
that provides vertical guidance (i.e. ILS or GPS WAAS approach)
• The pilot is attempting to add an altitude constraint to any waypoint past the FAF of an approach that does
not provide vertical guidance (i.e. not an ILS or GPS WAAS approach).
To enter altitudes as a flight level, enter an “F” in the most significant digit by rotating the inner FMS Knob
counter-clockwise past zero or clockwise past 9, the system will automatically change to show units of Flight
Level.
NOTE: Vertical constraints and Along Track offset waypoints are not retained in stored flight plans.
NOTE: When an altitude constraint is subdued it means that the user has selected a vertical profile that
cannot be flown. The computed FPA for adjacent vertical constraints is too steep.

ALONG TRACK OFFSETS
The pilot can enter a waypoint having an “along track offset” distance from an existing waypoint. Offset
distances can be entered from 1 to 99 nautical miles in increments of 1 nautical mile before the offset waypoint
(shown as a negative value) or after the offset waypoint (shown as a positive value).
A waypoint is allowed as long as the along track offset places the waypoint adjacent to its parent waypoint
in the lateral flight plan.
An along track offset that places a waypoint after the final approach fix of an approach is not allowed. Along
track offset waypoints lie along the great circle path of the existing lateral flight plan. Assigning an along
track offset to a leg with indeterminate length is not permitted. Creating an along track offset waypoint that
is located past the final approach fix waypoint is not permitted.
Entering a negative offset distance results in an along track offset waypoint inserted before the selected
lateral waypoint, whereas entering a positive offset distance results in an along track offset waypoint inserted
after the selected lateral waypoint. The creation of multiple along track offset waypoints is allowed.
NOTE: If the CLR Key is pressed prior to completing the definition of the along track offset waypoint, the
along track offset waypoint will be removed.
NOTE: An along track offset distance cannot be modified once entered. If the along track offset distance
must be changed, the pilot must delete the existing along track offset waypoint and create a new one with
the corrected offset distance.
Entering an along track offset distance:
1) Select the Active Flight Plan Page.
2) Select the desired lateral waypoint.
3) Press the ATK OFST Softkey.
4) Enter a positive or negative offset distance in the range of +/- 1 to 99 nautical miles (Figure 5-74). NOTE: The
offset also cannot exceed the distance to the next or previous lateral non-ATK offset waypoint.

• Changing the target vertical speed for the descent segment
Changes to the VNAV profile apply to the current active waypoint only. The VNAV profile is not
modifiable if there is no active waypoint. An invalid entry results in the previous value being restored.
The VNAV profile modification is invalid if it results in any of the following conditions:
• The maximum allowed FPA is exceeded
• The calculated target vertical speed exceeds the maximum allowed
• The TOD point is now located behind the aircraft’s present position or an s-turn would be required to
capture the modified vertical profile

The VS TGT will be computed using the FPA and current ground speed and updated on the display
periodically. If there is an active waypoint with a vertical component, a valid ground speed, and the
system determines the aircraft is airborne, the pilot can select and modify the VS TGT. Updates to
the field will cease when the field is selected for modification. The VS TGT may be changed using the
following sequence of actions:
Modifying the VS TGT:
1) Press the VNV PROF Softkey.
2) Use the small FMS Knob, or enter the desired value or to modify the value.
3) Press the VNV PROF Softkey again when finished or press the FMS Knob to remove the cursor from the VNAV
Profile (NOTE: VS TGT must be negative and cannot be less than the configured minimum value).
Upon completion of entering a new VS TGT the G1000:
• Periodically computes a new FPA using the selected VS TGT and current ground speed until the TOD
is reached
• Uses the newly computed FPA for the active waypoint with a vertical component
• Resumes periodic updates of the VS TGT using the new FPA and current ground speed. VNAV profile
changes apply to the active waypoint only.
The active waypoint with a vertical component and its FPA is shown in the current VNAV profile
information box. The pilot can change the FPA.
Modifying the flight path angle:
1) Select the FPA by pressing the VNV PROF Softkey followed by a clockwise turn of the large FMS Knob. It can
also be selected by scrolling past the end of the active flight plan waypoint list.
2) Modify the value using either the small FMS Knob or the GCU 475 Control Unit. The FPA must be negative and
cannot be less than the configured minimum value.

5.21 PROCEDURES (MFD)
ARINC 424 DATABASE LEG TYPES SUPPORTED BY THE G1000 FOR CESSNA NAV III
ARINC 424 is an industry standard that specifies the contents and format of the database that is used by all
manufacturers of RNAV equipment. This includes basic GPS navigators as well as Flight Management Systems
on corporate jets or air transport airplanes.
The basic database provided to manufacturers by Jeppesen typically has all waypoints, airways, departure
procedures, arrival procedures, and instrument approach procedures embedded within it. The difference
between most manufacturers is how much of the data in the database is utilized and what data is thrown away.
Depending upon the level of capability of a particular navigation system, some or most of this data may not
be used. If a navigation system can only perform Direct-To waypoint functions, or provide basic waypoint to
waypoint flight planning, then the only data that would be preserved for use by the customer would be the
waypoints themselves. In the case of a full-featured system such as the G1000, the full set of data is preserved
to allow the pilot to select data as necessary in order to provide complete flight planning and guidance to the
pilot.
There are currently 23 different database leg types. The G1000 is designed to interpret the database and
discern between a simple waypoint to waypoint leg, or a leg which specifies a specific heading until reaching an
altitude constraint (i.e. fly heading 120 degrees until reaching 1000’ MSL.)
The leg types in the database are formatted in a variety of ways to comply with the various instructions and
constraints typical in an instrument procedure. All 23 published procedures and leg types are supported by the
G1000 and available to the pilot for flight planning.
• AF - DME arc to a fix
• CF – Course to a fix
• DF – Direct to a fix
• FA – Course from fix to an altitude
• FC – Course from fix to distance
• FD – Course from fix to DME distance
• FM – Course from fix to manual termination
• HA – Hold terminating at altitude
• HF – Hold terminating at a fix
• HM – Hold with manual termination
• IF – Initial fix
• PI – Procedure turn to course intercept
• RF – Constant radius turn to fix
• TF – Track between two fixes
• CA – Course to an altitude

APPROACH OPERATIONS
Since not all approaches in the database are approved for GPS use. When selecting an approach, a “GPS”
designation to the right of the procedure name indicates the procedure can be flown using the GPS receiver.
Some procedures will not have this designation, meaning the GPS receiver can be used for supplemental
navigation guidance only. If the GPS receiver cannot be used for primary guidance, the appropriate
navigation receiver must be used for the selected approach (e.g., VOR or ILS). The final course segment of
ILS approaches, for example, must be flown by tuning the NAV receiver to the proper frequency and selecting
that NAV receiver on the CDI.
All WAAS approaches (LNAV, LNAV+V, L/VNAV, and LPV) are displayed in the list of available approaches
(Figure 5-90) and will give vertical guidance up to the IAF. The WAAS approach may be activated at any point
to proceed directly to the IAF. It should be noted that a lateral flight plan (LNAV) does not include vertical
guidance after the Final Approach Fix.

USING XM WX SATELLITE WEATHER PRODUCTS
The Weather Data Link Page is in the Map group of pages. It is the primary starting point for viewing weather
data because it can display all available XM weather products. No other G1000 page can display all XM weather
products.
When a weather product is active on the Weather Data Link Page or the Navigation Map Page, the age of the
data displays on the screen. This represents the age of the product, based on the difference between when the
data was assembled on the ground and the current GPS time (Figure 6-2).
Weather products are refreshed at specific intervals as defined in the Refresh Rate column in Table 6-1.
The refresh rate represents the interval at which XM Satellite Radio broadcasts new signals that may or may not
contain new weather data. It does not represent the rate at which weather data is updated or new content is
received by the Data Link Receiver. Weather data and new content are updated at intervals that are defined and
controlled by XM Satellite Radio and its data vendors.
If, for any reason, a weather product is not refreshed within 30-, 60-, or 90-minute intervals as defined in
the Expiration Time column in Table 6-1, the data is considered expired and is removed from the display.
This ensures that the displayed data is consistent with what is currently being broadcast by XM Satellite Radio
services. If more than half of the expiration time has elapsed, the color and time displayed in the upper right
corner of the Weather Data Link Page changes from light blue to amber.

NEXRAD
NOTE: The TOPO and/or TERRAIN display and NEXRAD are mutually exclusive for all applicable maps.
NEXRAD (NEXt-generation RADar) is a network of 158 high-resolution Doppler radar systems that are
operated by the National Weather Service (NWS). Its technical name is WSR-88D.
NEXRAD data provides centralized meteorological information for the continental United States and selected
overseas locations. The maximum range of a single NEXRAD radar site is 250 nautical miles. In addition to
a wide array of services, the NEXRAD network provides important information about severe weather and air
traffic safety.
NEXRAD data is not real-time. The lapsed time between collection, processing, and dissemination of
NEXRAD images can be significant and may not reflect the current radar synopsis. Due to the inherent delays
and the relative age of the data, it should be used for long-range planning purposes only. Never use NEXRAD
data or any radar data to penetrate hazardous weather. Rather, use it in an early-warning capacity of predeparture and enroute evaluation.

HAZARD AVOIDANCE
All weather product legends can be viewed on the Weather Data Link Page. For the NEXRAD legend
(Figure 6-5), press the LEGEND Softkey when NEXRAD is selected for display.
Figure 6-5 NEXRAD Data with Legend
The display of radar coverage is always active when either NEXRAD or ECHO TOPS is selected. The
display indicates the currently available NEXRAD radar coverage and Echo Tops areas in a grayish-purple
color where information is unavailable or is not being collected. This means that the radar capability exists
in the grayish-purple areas, but that it is not active or is off-line.
REFLECTIVITY
Reflectivity is the amount of transmitted power returned to the radar receiver. Colors on the NEXRAD
display are directly correlative to the level of detected reflectivity. Reflectivity as it relates to hazardous
weather can be very complex.
The role of radar is essentially to detect moisture in the atmosphere. Simply put, certain types of weather
reflect radar better than others. The intensity of a radar reflection is not necessarily an indication of the
weather hazard level. For instance, wet hail returns a strong radar reflection, while dry hail does not. Both
wet and dry hail can be extremely hazardous.
The different NEXRAD echo intensities are measured in decibels (dB) relative to reflectivity (Z). NEXRAD
measures the radar reflectivity ratio, or the energy reflected back to the radar receiver (designated by the
letter Z). The value of Z increases as the returned signal strength increases.

HAZARD AVOIDANCE
NEXRAD LIMITATIONS
NEXRAD radar images may have certain limitations:
• NEXRAD base reflectivity does not provide sufficient information to determine cloud layers or precipitation
characteristics (wet hail vs. rain). For example, it is not possible to distinguish between wet snow, wet
hail, and rain.
• NEXRAD base reflectivity is sampled at the minimum antenna elevation angle. An individual NEXRAD
site cannot depict high altitude storms at close ranges. It has no information about storms directly over
the site.
• When zoomed in to a range of 30 nm, each square block on the display represents an area of four square
kilometers. The intensity level reflected by each square represents the highest level of NEXRAD data
sampled within the area (Figure 6-6).
Each block has an Area
of 4 sq. km
Figure 6-6 NEXRAD Data - Zoomed
NEXRAD radar images may display abnormalities:
• Ground clutter
• Strobes and spurious radar data
• Sun strobes (when the radar antenna points directly at the sun)
• Interference from buildings or mountains, which may cause shadows
• Metallic dust from military aircraft, which can cause alterations in radar scans

ECHO TOPS
NOTE: Echo Tops is mutually exclusive with Cloud Tops and NEXRAD.
Echo Tops data (Figure 6-7) shows the location, elevation, and direction of the highest radar echo. The
highest radar echo does not indicate the top of a storm or clouds; rather it indicates the highest altitude at
which precipitation is detected. The information is derived from NEXRAD data.

6.3 TERRAIN PROXIMITY
WARNING: Do not use Terrain Proximity information for primary terrain avoidance. Terrain Proximity is
intended only to enhance situational awareness.
NOTE: Terrain data is not displayed when the aircraft latitude is greater than 75° North or 60° South.
NOTE: Terrain Proximity is only available when TAWS is not enabled.
G1000 Terrain Proximity is a non-TSO-C151b-certified terrain awareness system. It increases situational
awareness and aids in reducing controlled flight into terrain (CFIT).
Do not confuse Terrain Proximity with Terrain Awareness and Warning System (TAWS). TAWS is more
sophisticated and robust, and it is TSO-C151b certified. Terrain Proximity does not provide warning annunciations
or voice alerts. It only provides color indications on map displays when terrain and obstacles are within a certain
altitude threshold from the aircraft. Although the terrain and obstacle color map displays are the same, TAWS
uses more sophisticated algorithms to assess aircraft distance from terrain and obstacles.
REQUIREMENTS
Terrain Proximity requires the following components to operate properly:
• Valid 3-D GPS position
• Valid terrain/obstacle database
GPS POSITION AND GPS-MSL ALTITUDE
The G1000 GPS receiver provides the horizontal position and altitude. GPS altitude is derived from satellite
position. GPS altitude is then converted to a mean sea level (MSL)-based altitude (GPS-MSL altitude) and is used
to determine terrain and obstacle proximity. GPS-MSL altitude accuracy is affected by satellite geometry, but is
not subject to variations in pressure and temperature that normally affect pressure altitude sensors. GPS-MSL
altitude does not require local altimeter settings to determine MSL altitude. It is a widely-used MSL altitude source.
Terrain and obstacle databases are referenced to MSL. Using the GPS position and altitude, the Terrain
Proximity feature portrays a 2-D picture of the surrounding terrain and obstacles relative to the position and
altitude of the aircraft. GPS position and GPS-MSL altitude are used to calculate and predict the aircraft’s flight
path in relation to the surrounding terrain and obstacles. In this way, the pilot can view predicted dangerous
terrain and obstacle conditions.
DISPLAYING TERRAIN PROXIMITY DATA
Terrain and obstacle information can be displayed on the following pages:
6-34

• AUX - Trip Planning Page
• Navigation Map
• PFD Inset Map

HAZARD AVOIDANCE
To display terrain and obstacle data on any page other than the Terrain Proximity Page, press the MAP Softkey,
then press the TERRAIN Softkey. Obstacles with heights greater than 200 feet above ground level (AGL) are
displayed in three color levels (Table 6-6). The G1000 adjusts colors automatically as the aircraft altitude changes.
Terrain Proximity may also be deselected from the Inset Map without affecting the terrain display on the MFD
maps.
Obstacles are displayed only at certain map zoom ranges, on certain maps, and will only be displayed if an
obstacle database is loaded on the SD card. In addition, all map zoom ranges are dependent on the zoom range
setting in the Navigation Map. If the zoom range on the Navigation Map is adjusted to below 20 nm, the highest
zoom range on all other maps is also adjusted proportionally.
Table 6-5 shows the map pages and the highest zoom range at which obstacles are displayed.

6.4 TAWS
TAWS (Terrain Awareness and Warning System) is an optional feature to increase situational awareness and aid
in reducing controlled flight into terrain (CFIT). TAWS satisfies TSO-C151b Class B requirements for certification.
Class B TAWS is required for all Part 91 aircraft operations with six or more passenger seats and for Part 135
turbine aircraft operations with six to nine passenger seats (FAR Parts 91.223, 135.154).
TAWS provides visual and aural annunciations when terrain and obstacles are within the given altitude threshold
from the aircraft.
REQUIREMENTS
TAWS requires the following to operate properly:
• The system must have a valid 3-D GPS position solution.
• The system must have a valid terrain/obstacle/airport terrain database.
LIMITATIONS
NOTE: The data contained in the TAWS databases comes from government agencies. Garmin accurately
processes and cross-validates the data but cannot guarantee the accuracy and completeness of the data.
TAWS displays terrain and obstructions relative to the altitude of the aircraft. The displayed alerts and
warnings are advisory in nature only. Individual obstructions may be shown if available in the database.
However, all obstructions may not be available in the database and data may be inaccurate. Never use this
information for navigation or to maneuver to avoid obstacles.
Terrain information is based on terrain elevation information in a database that may contain inaccuracies.
Terrain information should be used as an aid to situational awareness. Never use it for navigation or to
maneuver to avoid terrain.
TAWS uses terrain and obstacle information supplied by government sources. The data undergoes verification
by Garmin to confirm accuracy of the content, per TSO-C151b. However, the displayed information should
never be understood as being all-inclusive.
TAWS ALERTING USING THE GPS POSITION/GPS-MSL ALTITUDE
TAWS uses information provided from the GPS receiver to provide a horizontal position and altitude. GPS
altitude is derived from satellite measurements. GPS altitude is converted to a mean sea level (MSL)-based
altitude (GPS-MSL altitude) and is used to determine TAWS alerts. GPS-MSL altitude accuracy is affected by
factors such as satellite geometry, but it is not subject to variations in pressure and temperature that normally
affect pressure altitude devices. GPS-MSL altitude does not require local altimeter settings to determine MSL
altitude. Therefore, GPS altitude provides a highly accurate and reliable MSL altitude source to calculate terrain
and obstacle alerts.
TAWS utilizes terrain and obstacle databases that are referenced to mean sea level (MSL). Using the GPS
position and GPS-MSL altitude, TAWS displays a 2-D picture of the surrounding terrain and obstacles relative
to the position and altitude of the aircraft. Furthermore, the GPS position and GPS-MSL altitude are used to
calculate and “predict” the aircraft’s flight path in relation to the surrounding terrain and obstacles. In this
190-00498-01 Rev. A

HAZARD AVOIDANCE
manner, TAWS can provide advanced alerts of predicted dangerous terrain conditions. Detailed alert modes
are described later in this section.
BARO-CORRECTED ALTITUDE VERSUS GPS-MSL ALTITUDE
Baro-corrected altitude (or indicated altitude) is derived by adjusting the altimeter setting for local
atmospheric conditions. The most accurate baro-corrected altitude can be achieved by frequently updating
the altimeter setting to the nearest reporting station along the flight path. However, because actual atmosphere
conditions seldom match the standard conditions defined by the International Standard Atmosphere (ISA)
model (where pressure, temperature, and lapse rates have fixed values), it is common for the baro-corrected
altitude (as read from the altimeter) to differ from the GPS-MSL altitude. This variation results in the aircraft’s
true altitude differing from the baro-corrected altitude.
USING TAWS
During G1000 power-up, the terrain/obstacle database versions are displayed along with a disclaimer to the
pilot. At the same time, TAWS self-test begins. One of the following aural messages is generated:
• “TAWS System Test OK”
• “TAWS System Failure”
TAWS information can be displayed on the following pages:
• TAWS Page
• Navigation Map
• PFD Inset Map
• AUX - Trip Planning Page
• Flight Plan Pages
TAWS can also be displayed on the PFD Inset Map by pressing the INSET Softkey, then the TERRAIN
Softkey. TAWS display may also be deselected from the Inset Map without affecting the display on the MFD
maps.
To display TAWS data on any page other than the TAWS Page, press the MAP Softkey, then press the TERRAIN
Softkey. Terrain and obstacles with heights greater than 200 feet above ground level (AGL) are displayed in
three color levels (Table 6-8). The G1000 adjusts colors automatically as the aircraft altitude changes.

FORWARD LOOKING TERRAIN AVOIDANCE
The Forward Looking Terrain Avoidance (FLTA) alert is used by TAWS and is composed of:
• REDUCED REQUIRED TERRAIN CLEARANCE AND REDUCED REQUIRED OBSTACLE CLEARANCE
Reduced Required Terrain Clearance (RTC) and Reduced Required Obstacle Clearance (ROC) alerts are
issued when the aircraft flight path is above terrain, yet is projected to come within the minimum clearance
values in Table 6-11. When an RTC alert is issued, a potential impact point is displayed on the TAWS
Page.
• IMMINENT TERRAIN IMPACT AND IMMINENT OBSTACLE IMPACT
Imminent Terrain Impact (ITI) and Imminent Obstacle Impact (IOI) alerts are issued when the aircraft
is below the elevation of a terrain or obstacle cell in the aircraft’s projected path. ITI and IOI alerts are
accompanied by a potential impact point displayed on the TAWS Page. The alert is annunciated when the
projected vertical flight path is calculated to come within minimum clearance altitudes in Table 6-11.

PREMATURE DESCENT ALERTING
A Premature Descent Alert (PDA) is issued when the system detects that the aircraft is significantly below
the normal approach path to a runway (Figure 6-54).
PDA alerting begins when the aircraft is within 15 nm of the destination airport and ends when the aircraft
is either 0.5 nm from the runway threshold OR is at an altitude of 125 feet AGL while within 1.0 nm of the
threshold. During the final descent, algorithms will set a threshold for alerting based on speed, distance, and
other parameters.

‘FIVE-HUNDRED’ AURAL ALERT
The purpose of the aural alert message “Five-hundred” is to provide an advisory alert to the pilot that the
aircraft is 500 feet above terrain. When the aircraft descends within 500 feet of terrain, the aural message
“five-hundred” is generated. There are no display annunciations or pop-up alerts that accompany the aural
message.
TAWS NOT AVAILABLE ALERT
TAWS requires a 3-D GPS navigation solution along with specific vertical accuracy minimums. Should the
navigation solution become degraded or if the aircraft is out of the database coverage area, the annunciation
‘TAWS N/A’ is generated in the annunciation window and on the TAWS Page. The aural message “TAWS Not
Available” is generated. When the GPS signal is re-established and the aircraft is within the database coverage
area, the aural message “TAWS Available” is generated.
TAWS FAILURE ALERT
TAWS continually monitors several system-critical items such as database validity, hardware status, and
GPS status. If the terrain/obstacle database is not available, the aural message “TAWS System Failure” is
generated along with a ‘TAWS FAIL’ annunciation.

TIS SYMBOLOGY
Traffic Information Service (TIS) is designed to help pilots detect and avoid aircraft intersecting their flight
path. TIS uses the Mode S transponder for the traffic data link.
TIS receives traffic information from ground stations and provides a five-second update rate. The G1000
displays up to eight traffic targets within a 7.5 nm radius, from 3000 feet below to 3500 feet above the
requesting aircraft. Traffic is displayed according to TCAS symbology using four different symbols (Table 612).
TIS Symbol
Description
Non-Threat Traffic
Proximity Advisory (PA)
Traffic Advisory (TA)
Traffic Advisory Off Scale
Table 6-12 TIS Symbol Descriptions
Proximity Advisories (PAs) are defined as traffic within the 5.0-nm range, within ±1200 feet of altitude
separation. They are not Traffic Advisories (TA), which alert the crew to intruding aircraft. When traffic meets
the advisory criteria for the TA, a solid yellow circle symbol is generated. TIS provides vector lines showing
the direction in which the aircraft symbol is moving.
Deviation from aircraft altitude is displayed above or below the target symbol, depending on the traffic
location. Altitude trend is displayed as an up (+500 ft/min) or down (-500 ft/min) arrow to the right of the
target symbol. If the altitude trend is less than 500 ft/min rate in either direction, no arrow displays.

TIS POWER-UP TEST
The TIS system performs an automatic test during power-up. If the system passes the power-up test, the
standby screen is displayed on the Traffic Map Page. If the aircraft is airborne during the test, traffic is displayed
on the Traffic Page.
If the system fails the power up test, one of the following messages displays:
• NO DATA - Indicates that data is not being received from the transponder.
• DATA FAILED - Indicates that data is being received from the transponder, but a failure was detected in the
data stream.
• FAILED - Indicates that the transponder has failed.
Contact the service center or Garmin dealer for corrective action for these messages.

Once the aircraft is airborne, the system switches from Standby mode to Operating mode. The G1000
displays ‘TIS OPERATING’ in the upper left-hand corner and begins to display traffic on the Traffic Map Page.
The TIS Traffic Advisory (TA) alerts the crew to intruding aircraft.
Once the aircraft is on the ground the system switches from operating mode to standby mode. The Traffic
Map Page displays ‘STANDBY’. The pilot can use the page menu or softkeys to switch between Standby (STBY)
and Operating (ON) modes and manually override automatic operation.
Switching between operating modes:
1) Select the Map Page Group.
2) Select the Traffic Map Page.

OR:
1) Press the MENU Key. The page menu displays ‘Standby Mode’ or ‘Operate Mode’.
2) Press the ENT Key on the desired selection.
AUDIO ALERTS
An audio alert is generated whenever the number of TAs on the Traffic Map Page increases from one scan
to the next. This reduces the amount of nuisance alerts due to proximate aircraft. For example, when the
first TA is displayed, an aural alert is generated. As long as a single TA aircraft remains on the display, no
additional alerts are generated. If a second TA aircraft appears on the display, a new audio alert is generated.
If the number of TAs initially decreases and then subsequently increases, another audio alert is generated.
An audio alert is also generated when the TIS service becomes unavailable. The volume of the audio alert
is configured during installation.
The following alerts are available:
• Traffic - Traffic alert is received.
• TIS Not Available - TIS is not available or out of range.
To disable the TIS Not Available nuisance alert, press the TNA MUTE Softkey (Figure 6-59).

SECTION 7 AUTOMATIC FLIGHT CONTROL SYSTEM
7.1 AFCS OVERVIEW
NOTE: The approved Pilot’s Operating Handbook (POH) always supersedes this Pilot’s Guide.
NOTE: The GFC 700 AFCS is not available for the Cessna 172.
NOTE: A failure of the primary (#1) GIA 63 Integrated Avionics Unit (IAU) results in loss of the flight director.
Any IAU failure results in loss of the autopilot and manual electric trim.
The GFC 700 is a digital Automatic Flight Control System (AFCS), fully integrated within the G1000 System
avionics architecture. The System Overview section provides a block diagram to support this system description.
GFC 700 AFCS functionality in Cessna Nav III aircraft is distributed across the following Line Replaceable
Units (LRUs):
• GDU 1044B Primary Flight Display (PFD)
• GSA 81 AFCS Servo (3)
• GDU 1044B Multi-Function Display (MFD)
• GSM 85 Servo Mounts (3)
• GIA 63/63W Integrated Avionics Units (2)
The GFC 700 AFCS can be divided into these main operating functions:
• Flight Director (FD) — Flight director operation takes place within the primary (#1) GIA 63. Flight
director commands are displayed on the PFD.
The flight director provides:
– Command Bars showing pitch/roll guidance
– Pitch/roll mode selection and processing
– Autopilot communication
• Autopilot (AP) — Autopilot operation occurs within the pitch, roll, and pitch trim servo and provides servo
monitoring and automatic flight control in response to flight director steering commands, AHRS attitude and
rate information, and airspeed.
• Manual Electric Trim (MET) — The pitch trim servo provides manual electric trim capability when the
autopilot is not engaged.

ADDITIONAL AFCS CONTROLS
The following AFCS controls are located in the cockpit separately from the MFD:
Disengages the autopilot and interrupts pitch trim operation
AP DISC Switch
(Autopilot Disconnect) The red AP DISC switch is located forward of the MET Switch on the pilot’s
control wheel left grip.
This switch may be used to acknowledge an autopilot disconnect and mute the
associated aural tone.
CWS Button
(Control Wheel
Steering)
Momentarily disengages the autopilot and synchronizes the flight director’s
Command Bars with the current aircraft pitch (if not in a Vertical Navigation,
Glidepath, or Glideslope Mode) and roll (if in Roll Hold Mode)
The CWS button is located on the top of the pilot’s control wheel right grip.
Upon release of the CWS button, the flight director may establish new reference
points, depending on the current pitch and roll modes. CWS operation
details are discussed in the respective mode sections of this manual.
GA Switch (Go Around) Disengages the autopilot, selects flight director Go Around Mode, and activates
the missed approach
The GA Switch is located on the instrument panel above the throttle.
Used to command manual electric trim
MET Switch
(Manual Electric Trim) The MET Switch is located on the pilot’s control wheel left grip
This composite switch is split into left and right sides. The left switch is
the ARM contact and the right switch controls the DN (forward) and UP
(rearward) contacts. The MET ARM switch can be used to disengage the
autopilot and to acknowledge an autopilot disconnect alert and mute the
associated aural tone.
Manual trim commands are generated only when both sides of the switch are
operated simultaneously. If either side of the switch is active separately for
more than three seconds, MET function is disabled and ‘PTRM’ is displayed
as the AFCS Status Annunciation on the PFD. The function remains disabled
until both sides of the switch are inactivated.

7.2 FLIGHT DIRECTOR OPERATION
The flight director function provides pitch and roll commands to the AFCS and displays them on the PFD.
With the flight director activated, the aircraft can be hand-flown to follow the path shown by the Command Bars.
Maximum commanded pitch (+20°/-15°) and bank (22°) angles, vertical acceleration, and roll rate are limited to
values established during AFCS certification. The flight director also provides commands to the autopilot.
ACTIVATING THE FLIGHT DIRECTOR
Pressing the FD or AP Key (when the flight director is not active) activates the flight director in default pitch/
roll modes. Pushing the GA Switch or any fight director mode key activates the flight director in the respective
mode(s). The flight director may be turned off by pressing the FD Key. The FD Key is disabled when the
autopilot is engaged.
COMMAND BARS
Upon activation of the flight director, Command Bars are displayed on the PFD as a single magenta cue. The
Command Bars move together vertically to indicate pitch commands and bank left or right to indicate roll
commands. The Command Bars do not override the aircraft symbol.
If the attitude information sent to the flight director becomes invalid or unavailable, the Command Bars are
removed from the display. The flight director Command Bars also disappear if the pitch exceeds +30˚/-20˚ or
bank exceeds 65˚.

AUTOMATIC FLIGHT CONTROL SYSTEM
7.3 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 10 seconds.
If the information required to compute a flight director mode becomes invalid or unavailable, the flight director
automatically reverts to the default mode for that axis. A flashing yellow mode annunciation and annunciator
light indicate loss of sensor (AHRS, ADC, IAU) or navigation data (VOR, LOC, GPS, VNAV, WAAS) required to
compute commands. When such a loss occurs, the system automatically begins to roll the wings level (enters Roll
Hold Mode) or maintain the pitch angle (enters Pitch Hold Mode), depending on the affected axis. The flashing
annunciation stops when the affected mode key is pressed or another mode for the axis is selected. If after 10
seconds no action is taken, the flashing annunciation stops.
Figure 7-4 Loss of VOR Signal
The flight director is automatically disabled if the attitude information required to compute the default flight
director modes becomes invalid or unavailable.
PITCH MODES
The GFC 700 AFCS offers the following pitch modes:
• Pitch Hold (default mode)— Holds the current aircraft pitch attitude; may be used to climb/descend to the
Selected Altitude
• Selected Altitude Capture — Captures the Selected Altitude
• Altitude Hold — Holds the current Altitude Reference
• Vertical Speed — Maintains the current aircraft vertical speed; may be used to climb/descend to the Selected
Altitude
• Flight Level Change — Maintains the current aircraft airspeed while the aircraft is climbing/descending to
the Selected Altitude

• Vertical Path Tracking — Captures and tracks descent legs of an active vertical profile
• VNAV Target Altitude Capture — Captures the Vertical Navigation (VNAV) Target Altitude
• Glidepath — Captures and tracks the WAAS glidepath on approach (only available in installations with GIA
63W Integrated Avionics Units and when WAAS is available)
• Glideslope — Captures and tracks the ILS glideslope on approach
• Go Around — Automatically disengages the autopilot and commands a constant pitch angle and wings level
while in the air
Table 7-1 lists the pitch modes with their corresponding controls and annunciations. The mode reference
is displayed next to the active mode annunciation for Altitude Hold, Vertical Speed, and Flight Level Change
modes. The NOSE UP/NOSE DN keys can be used to change the pitch mode reference while operating under

PITCH HOLD MODE (PIT)
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.
In Pitch Hold Mode, the flight director maintains a constant pitch attitude, the pitch reference. The pitch
reference is set to the aircraft pitch 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/down limit.
CHANGING THE PITCH REFERENCE
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

SELECTED ALTITUDE CAPTURE MODE (ALTS)
Selected Altitude Capture Mode is automatically armed with activation of the following modes:
• Go Around
• Pitch Hold
• Vertical Path Tracking (if the Selected Altitude
is to be captured instead of the VNAV Target
• Flight Level Change
Altitude)
The white ‘ALTS’ annunciation indicates Selected Altitude Capture Mode is armed (see Figure 7-6 for
example). The ALT Knob is used to set the Selected Altitude (shown above the Altimeter) until Selected
Altitude Capture Mode becomes active.
• Vertical Speed
As the aircraft nears the Selected Altitude, the flight director automatically transitions to Selected Altitude
Capture Mode with Altitude Hold Mode armed (Figure 7-6). This automatic transition is indicated by the
green ‘ALTS’ annunciation flashing for up to 10 seconds and the appearance of the white ‘ALT” annunciation.
The Selected Altitude is shown as the Altitude Reference beside the ‘ALTS’ annunciation.
At 50 feet 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 10 seconds to indicate the automatic transition.

AUTOMATIC FLIGHT CONTROL SYSTEM
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 10 feet) as the Altitude Reference. The flight director’s Altitude Reference,
shown in the AFCS Status Box, 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
(see Figure 7-6). Selected Altitude Capture Mode automatically transitions to Altitude Hold Mode when the
altitude error is less than 50 feet. 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 hand-flown to a new Altitude Reference. When the
CWS Button is released at the desired altitude, the new altitude is established as the Altitude Reference.
If the Selected Altitude is reached during CWS maneuvering, the Altitude Reference is not changed. To
adjust the Altitude Reference in this case, the CWS Button must be pressed again after the Selected Altitude
is reached.

VERTICAL SPEED MODE (VS)
In Vertical Speed Mode, the flight director acquires and maintains a Vertical Speed Reference. Current
aircraft vertical speed (to the nearest 100 fpm) becomes the Vertical Speed Reference at the moment of Vertical
Speed Mode activation. 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 Vertical Speed Mode is
selected.
When Vertical Speed Mode is activated by pressing the VS Key, ‘VS’ is annunciated in green in the AFCS
Status Box along with the Vertical Speed Reference. The Vertical Speed Reference is also displayed above the
Vertical Speed Indicator. A Vertical Speed Reference Bug corresponding to the Vertical Speed Reference is
shown on the indicator.

FLIGHT LEVEL CHANGE MODE (FLC)
NOTE: The Selected Altitude should be set before selecting Flight Level Change Mode.
Flight Level Change Mode is selected by pressing the FLC Key. This mode acquires and maintains the
Airspeed Reference while climbing or descending to the Selected Altitude (shown above the Altimeter). When
Flight Level Change Mode is active, the flight director continuously monitors Selected Altitude, airspeed, and
altitude.
The Airspeed Reference is set to the current airspeed upon mode activation. Flight Level Change Mode is
indicated by a green ‘FLC’ annunciation beside the Airspeed Reference in the AFCS Status Box. The Airspeed
Reference is also displayed directly above the Airspeed Indicator, along with a bug corresponding to the
Airspeed Reference along the tape.
Engine power must be adjusted to allow the autopilot to fly the aircraft at a pitch attitude corresponding
to the desired flight profile (climb or descent) while maintaining the Airspeed Reference. The flight director
maintains the current altitude until either engine power or the Airspeed Reference are adjusted and does not
allow the aircraft to climb or descend away from the Selected Altitude.
CHANGING THE AIRSPEED REFERENCE
The Airspeed Reference (shown in both the AFCS Status Box and above the Airspeed Indicator) may be

VERTICAL NAVIGATION MODES (VPTH, ALTV)
NOTE: VNV is disabled when parallel track is active. Refer to the GPS Navigation Section for more information
on VNV flight plans.
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 directto 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.
VNAV flight director pitch modes are only available when the selected navigation source is GPS. Upon
reaching the last waypoint in the VNAV flight plan, the flight director transitions to Altitude Hold Mode and
cancels any armed VNAV modes.
VERTICAL PATH TRACKING MODE (VPTH)
NOTE: If another pitch mode key is pressed while Vertical Path Tracking Mode is selected, Vertical Path
Tracking Mode reverts to armed.
NOTE: Pressing the CWS Button while Vertical Path Tracking Mode is active does not cancel the mode. The
autopilot guides the aircraft back to the descent path upon release of the CWS Button.
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 7-10 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 feet. 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 starts 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 and
the descent is not captured.

Automatic Pitch Hold Reversion
Several situations can occur while Vertical Path Tracking Mode is active which cause the flight director
to revert to Pitch Hold Mode. Vertical Path Tracking and the appropriate altitude capture modes are
armed for possible descent profile recapture if the vertical deviation:
• Exceeds 200 feet during an overspeed condition
• Experiences a discontinuity exceeding 200 feet due to a flight plan change
• Becomes invalid due to excessive crosstrack or track angle error
• Cannot be computed for a leg type (such as a hold or procedure turn)
The following circumstances cause mode reversion without arming Vertical Path Tracking Mode:
• Navigation source manually changed from GPS (with the CDI Softkey)
• CNCL VNV Softkey selected on the Active Flight Plan Page (MFD)
• All remaining vertical waypoints deleted from the flight plan
Non-Path Descents
Pitch Hold, Vertical Speed, and Flight Level Change modes can also be used to fly non-path descents
while 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 re-capture.
Figure 7-13 Flight Level Change VNAV Non-Path Descent
To prevent immediate profile re-capture, the following must be satisfied:
• At least 10 seconds have passed since the non-path transition was initiated
• Vertical deviation from the profile has exceeded 250 feet, but is now less than 200 feet
Pressing the VNV Key twice re-arms Vertical Path Tracking for immediate profile re-capture.

VNAV TARGET ALTITUDE CAPTURE MODE (ALTV)
NOTE: Armed VNV Target Altitude and Selected Altitude capture modes are mutually exclusive. However,
Selected Altitude Capture Mode is armed implicitly (not annunciated) whenever VNV Target Altitude Capture
Mode is armed.
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 Status Box, the active VNAV Target Altitude is displayed above the Vertical
Speed Indicator (see Figure 7-11).
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 10 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 feet 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 10 seconds to
indicate the automatic transition. The flight director automatically arms Vertical Path Tracking, allowing
upcoming descent legs to be captured and subsequently tracked.

Changing the current VNAV Target Altitude while VNAV Target Altitude Capture Mode is active causes
the flight director to revert to Pitch Hold Mode. Vertical Path Tracking and the appropriate altitude
capture mode are armed in preparation to capture the new VNAV Target Altitude or the Selected Altitude,
depending on which altitude is to be intercepted first.
VNAV target altitudes can be changed while editing the active flight plan (see the GPS Navigation

NOTE: Glidepath Mode is available only in installations with GIA 63W Integrated Avionics Units and when
WAAS is available.
Upon reaching the glidepath, the flight director transitions to Glidepath Mode and begins to capture and
track the glidepath. Glidepath mode is used to track the WAAS-based glidepath. Arming Glidepath Mode
(annunciated in white as ‘GP’) requires:
• Approach supporting WAAS vertical guidance is loaded into the flight plan
• Expected availability of vertical guidance
• GPS Approach Mode is selected (GPS is the selected navigation source and the APR Key is pressed; see GPS

NOTE: The selected navigation receiver must have a valid VOR or LOC signal or active GPS course for the
flight director to enter Navigation Mode.
Pressing the NAV Key selects Navigation Mode. Navigation Mode acquires and tracks the selected navigation
source (GPS, VOR, LOC). The flight director follows GPS roll steering commands when GPS is the selected
navigation source. When the navigation source is VOR or LOC, the flight director creates roll steering
commands from the Selected Course and deviation. Navigation Mode can also be used to fly non-precision
GPS and LOC approaches where glideslope capture is not required.
If the Course Deviation Indicator (CDI) shows greater than one dot when the NAV Key is pressed, the
selected mode is armed. The armed annunciation appears in white to the left of the active roll mode. For
cases where the projected course is offset a large distance from the present course for turn anticipation, GPS
Navigation Mode can be activated with crosstrack error up to 10 nm.

AUTOMATIC FLIGHT CONTROL SYSTEM
7.4 AUTOPILOT OPERATION
NOTE: Refer to the POH 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 servo 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 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 servo. 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 (MET).
This allows the aircraft to be trimmed using a control wheel switch rather than the trim wheel. Manual trim
commands are generated only when both halves of the MET Switch are operated simultaneously. Trim speeds
are scheduled with airspeed to provide more consistent response.
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 attitude-limited, 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.

CONTROL WHEEL STEERING
During autopilot operation, the aircraft may be hand-flown 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.
Control Wheel Steering
Figure 7-27 CWS Annunciation
DISENGAGING THE AUTOPILOT
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 threesecond autopilot disconnect aural alert. The AP DISC or MET ARM Switch may be used to cancel the aural
alert.
Autopilot Manually Disengaged
Figure 7-28 Manual Autopilot Disengagement
Automatic autopilot disengagement is indicated by a flashing red ‘AP’ annunciation and by the autopilot

Automatic disengagement occurs due to:
• System failure
• Invalid sensor data
• Inability to compute default flight director
modes (FD also disengages automatically)
• Stall warning

OVERSPEED PROTECTION
While Pitch Hold, Vertical Speed, Flight Level Change, Vertical Path Tracking, or an altitude capture mode is
active, airspeed is monitored by the flight director and pitch commands are limited for overspeed protection.
Overspeed protection is provided in situations where the flight director cannot acquire and maintain the mode
reference for the selected vertical mode without exceeding the certified maximum autopilot airspeed.
When an autopilot overspeed condition occurs, the Airspeed Reference appears in a box above the Airspeed
Indicator, flashing a yellow ‘MAXSPD’ annunciation. Engine power should be reduced and/or the pitch reference
adjusted to slow the aircraft. The annunciation disappears when the overspeed condition is resolved.

SECTION 8 ADDITIONAL FEATURES
NOTE: The availability of SafeTaxi, ChartView, or FliteCharts in electronic form does not preclude the
requirement to carry paper charts aboard the aircraft. See AC 120-76A for more information.
Additional features of G1000 include SafeTaxi™ diagrams, ChartView and FliteCharts™ electronic charts, and
XM Radio entertainment.
SafeTaxi diagrams provide detailed taxiway, runway, and ramp information at more than 650 airports in the
United States. By zooming in on an airport that has a SafeTaxi diagram available, a close up view of the airport
layout can be seen in detail.
The optional ChartView and FliteCharts provide on-board electronic terminal procedures charts. Electronic
charts offer the convenience of rapid access to essential information. Either ChartView or FliteCharts may be
configured in the system, but not both.
The optional XM Radio entertainment feature of the GDL 69A Data Link Receiver offers commercial-free
listening to entertainment audio. XM Radio offers more entertainment choices and longer range coverage than
commercial broadcast stations.
8.1 SAFETAXI
SafeTaxi is an enhanced feature that gives greater map detail when zooming in on airports at close range. The
maximum map ranges for enhanced detail are pilot configurable. When zoomed in close enough to show the
airport detail, the map reveals runways with numbers, taxiways with identifying letters/numbers, and airport
landmarks including ramps, buildings, control towers, and other prominent features. Resolution is greater at
lower map ranges. When the aircraft location is within the screen boundary, including within SafeTaxi ranges, an
airplane symbol is shown on any of the navigation map views for enhanced position awareness.

ADDITIONAL FEATURES
Any map page that displays the navigation view can also show the SafeTaxi airport layout within the maximum
configured range. The following is a list of pages where the SafeTaxi feature can be seen:
• NDB Information Page

• Inset map
• VOR Information Page
• Weather Datalink Page
• User Waypoint Information Page
• Airport Information Page

ANNUNCIATIONS AND 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.

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 A-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 A-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 A-4. Pressing the ADVISORY Softkey
acknowledges the presence of the message advisory alert and displays the alert text message in the Alerts
Window.

APPENDIX B
SD CARD USE
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.
JEPPESEN DATABASES
The Jeppesen aviation database is updated on a 28-day cycle. The ChartView database is updated on a 14day cycle. If the ChartView database is not updated within 70 days of the expiration date, ChartView will no
longer function.
Both these databases are provided directly from Jeppesen. The ChartView database should be copied to the
Garmin supplied Supplemental Data Card which will reside in the bottom card slot on the MFD. The aviation
database may be installed from the Jeppesen supplied SD data card or copied to one of the Garmin supplied
Supplemental Data Cards. Contact Jeppesen (www.jeppesen.com) for subscription and update information.
The aviation database may be programmed to only one of the Supplemental Data Cards. This card must then
be used to update the PFD and the MFD.
NOTE: After the aviation database is installed, the card may be removed after loading the update to each
LRU.
Updating the Jeppesen aviation database:
1) With the G1000 System OFF, insert the SD card containing the aviation database update into the top card slot
of the PFD to be updated (Label of SD card facing left).
2) Turn the G1000 System ON. A prompt similar to the following is displayed in the upper left corner of the PFD:
Figure B-1 Database Update Prompt
3) Press the ENT Key to start the database update. A prompt similar to the following is displayed:
Figure B-2 Database Update Confirmation
190-00498-01 Rev. A
Garmin G1000 Pilot’s Guide for Cessna Nav III
B-1
APPENDIX B
4) After the update completes, the PFD starts in normal mode.
5) Turn the G1000 System OFF and remove the SD card.
6) Repeat steps 1 through 4 for the MFD. The MFD and PFD databases are now updated. Remove the SD card
when finished.
7) Verify that the correct update cycle is loaded during startup of the MFD.
GARMIN DATABASES
The following G1000 databases are stored on Supplemental Data Cards provided by Garmin:
• Expanded basemap
• Obstacle
• Terrain
• SafeTaxi
• Airport terrain
• FliteCharts
A Supplemental Data Card should be inserted into the bottom card slot of the PFD and the MFD and not
removed except for updating the card. If one of the Supplemental Data Cards contains the ChartView database,
or the FliteCharts database, this card must be inserted into the bottom card slot on the MFD.
Since these databases are not stored internally in the MFD or PFD, a Supplemental Data Card containing
identical database versions must be kept in each display unit.
The basemap database contains data for the topography and land features, such as rivers, lakes, and towns.
It is updated only periodically, with no set schedule. There is no expiration date.
The terrain and airport terrain databases contain the terrain mapping and airport diagram data. They are
updated periodically and have no expiration date.
The obstacle database contains data for obstacles, such as towers, that pose a potential hazard to aircraft.
Obstacles 200 feet and higher are included in the obstacle database. It is very important to note that not all
obstacles are necessarily charted and therefore may not be contained in the obstacle database. This database is
updated on a 56-day cycle.
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.
The SafeTaxi database contains detailed airport diagrams for selected airports. These diagrams aid in following
ground control instructions by accurately displaying the aircraft position on the map in relation to taxiways,
ramps, runways, terminals, and services. This database is updated on a 56-day cycle.
The FliteCharts database contains procedure charts for the United States only. This database is updated on a
28-day cycle. If not updated within 180 days of the expiration date, FliteCharts will no longer function.

APPENDIX B
UPDATING GARMIN DATABASES
The Garmin database updates can be obtained by following the instructions detailed in the ‘Aviation
Databases’ section of the Garmin website (www.garmin.com). Once the updated files have been downloaded
from the website, a PC equipped with an appropriate SD card reader is used to unpack and program the
new databases onto the existing Supplemental Data Cards. Equipment required to perform the update is as
follows:
• Windows-compatible PC computer (Windows 2000 or XP recommended)
• SanDisk SD Card Reader, P/Ns SDDR-93 or SDDR-99 or equivalent card reader
• Updated database obtained from the Garmin website
• Existing 010-00330-42 Supplemental Database SD Cards from both PFD and MFD
After the data has been copied to the appropriate data cards, perform the following steps:
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 scrolling window of the splash screen. When updating the terrain and FliteCharts
databases, an ‘in progress’ message may be seen. If this message is present, wait for the system to finish
loading before verifying the correct databases are initialized, then proceed to step 3.
Figure B-3 Power-Up Splash Screen Window
3) Acknowledge the Power-up Page agreement by pressing the ENT Key or the right most softkey.
4) Turn the large FMS Knob to select the AUX Page group on the MFD.
5) Turn the small FMS Knob to select the System Status Page.
6) Press the DBASE Softkey to place the cursor in the ‘DATABASE’ box.
7) Turn either FMS Knob to scroll through the database list and check that all databases are current and there are
no errors.
8) Power down the G1000.

FREQUENTLY ASKED QUESTIONS
If a particular aspect of G1000 operational capability is not addressed by these commonly asked questions or in
the index, contact Garmin (see the copyright page or back cover for contact information) or a Garmin-authorized
dealer. Garmin is dedicated to supporting its products and customers.
WHAT IS WAAS?
The Wide Area Augmentation System (WAAS) uses a system of ground stations to correct any GPS signal
errors. These ground stations correct for errors caused by ionospheric disturbances, timing, and satellite
orbit errors. It also provides vital integrity information regarding the health of each GPS satellite. The signal
correction is then broadcast through one of two geostationary satellites. This correction information can then
be received by any WAAS-enabled GPS receiver.
WAAS is designed to provide the additional accuracy, availability, and integrity necessary to enable users to
rely on GPS for all phases of flight. WAAS is currently available in the United States, including Alaska and
Hawaii.
HOW DOES WAAS AFFECT APPROACH OPERATIONS?
Both LNAV/VNAV and LPV approaches use the accuracy of WAAS to include vertical (glide path) guidance
capability. The additional accuracy and vertical guidance capability allows improved instrument approaches to
an expanded number of airports throughout the U.S.
The implementation of LPV approaches further improves precision approach capabilities. LPV approaches
are designed to make full use of the improved GPS signal from the WAAS. This approach combines the LNAV/
VNAV vertical accuracy with lateral guidance similar to the typical Instrument Landing System (ILS). LPV
approaches allow lower approach minimums.
WHAT IS RAIM AND HOW DOES IT AFFECT APPROACH OPERATIONS?
RAIM is an acronym for Receiver Autonomous Integrity Monitoring. RAIM is a GPS receiver function that
performs the following functions:
• Monitors and verifies integrity and geometry of tracked GPS satellites
• Notifies the pilot when satellite conditions do not provide the necessary coverage to support a certain phase
of flight
• Predicts satellite coverage of a destination area to determine whether the number of available satellites is
sufficient to satisfy requirements
NOTE: If RAIM is not predicted to be available for the final approach course, the approach does not become
active, as indicated by the “RAIM not available from FAF to MAP” message and the LOI annunciation
flagging on the HSI.
For RAIM to work correctly, the GPS receiver must track at least five satellites. A minimum of six satellites is
required to allow RAIM to eliminate a single corrupt satellite from the navigation solution.
190-00498-01 Rev. A
Garmin G1000 Pilot’s Guide for Cessna Nav III
D-1
APPENDIX D
RAIM ensures that satellite geometry allows for a navigation solution calculation within a specified protection
limit (2.0 nm for oceanic and en route, 1.0 nm for terminal, and 0.3 nm for non-precision approaches). The
G1000 System monitors RAIM and issues an alert message when RAIM is not available (see Appendix A).
Without RAIM, GPS position accuracy cannot be monitored. If RAIM is not available when crossing the FAF,
the pilot must fly the missed approach procedure.
WHY ARE THERE NOT ANY APPROACHES AVAILABLE FOR A FLIGHT PLAN?
Approaches are available for the final destination airport in a flight plan or as a direct-to (keep in mind
that some VOR/VORTAC identifiers are similar to airport identifiers). If a destination airport does not have a
published approach, the G1000 indicates “NONE” for the available procedures.
WHAT HAPPENS WHEN AN APPROACH IS SELECTED? CAN A FLIGHT PLAN WITH AN APPROACH, A DEPARTURE, OR AN
ARRIVAL BE STORED?
When an approach, departure, or arrival is loaded into the active flight plan, a set of approach, departure,
or arrival waypoints is inserted into the flight plan, along with a header line showing the title of the selected
instrument procedure. The original en route portion of the flight plan remains active, unless the instrument
procedure is activated. This may be done either when the procedure is loaded or at a later time.
Flight plans can also be stored with an approach, a departure, or an arrival. Note that the active flight plan
is erased when the system is turned off. Also, the active flight plan is overwritten when another flight plan is
activated. When storing flight plans with an approach, a departure, or an arrival, the G1000 uses the waypoint
information from the current database to define the waypoints. If the database is changed or updated, the
G1000 System automatically updates the information, provided the procedure has not been modified. Should
an approach, departure, or arrival procedure no longer be available, the flight plan becomes locked until the
procedure is deleted from the flight plan.
CAN “SLANT GOLF” (“/G”) BE FILED USING THE G1000?
“/G” may be filed for a flight plan. The G1000 System meets the requirements of TSO-C129 Class A1
or A2 installation. Non-precision GPS approaches are not to be flown with an expired database. See the
approved Pilot’s Operating Handbook (POH) as well as the Aeronautical Information Manual (AIM) for more
information.
WHAT DOES THE OBS SOFTKEY DO?
The OBS Softkey is used to select manual sequencing of waypoints. Activating OBS mode sets the current
active-to waypoint as the primary navigation reference and prevents the system from sequencing to the next
waypoint in a flight plan. When OBS mode is cancelled, automatic waypoint sequencing is continued, and
the G1000 automatically activates the next waypoint in the flight plan once the aircraft has crossed the present
active waypoint.

Normal (OBS not activated)
• Automatic sequencing of waypoints
OBS
• Manual sequencing - ‘holds’ on selected
waypoint
• Manual course change on HSI not possible
• Manually select course to waypoint from
HSI
• Always navigates ‘TO’ the active waypoint
• Indicates ‘TO’ or ‘FROM’ waypoint
• Must be in this mode for final approach
course
• Cannot be set for final approach course or
published holding patterns
When OBS mode is active, the G1000 allows the pilot to set a desired course to/from a waypoint using the
CRS/BARO Knob and HSI (much like a VOR).
The most common application for using the OBS Softkey is the missed approach. The G1000 suspends
automatic waypoint sequencing (indicated by a ‘SUSP’ annunciation placed on the HSI) when the missed
approach point (MAP) is crossed. This prevents the G1000 from automatically sequencing to the missed
approach holding point (MAHP). During this time, the OBS Softkey designation changes to SUSP. Pressing
the SUSP Softkey reactivates automatic waypoint sequencing. The OBS Softkey then resumes its normal
functionality.
WHY DOES THE G1000 NOT AUTOMATICALLY SEQUENCE TO THE NEXT WAYPOINT?
The G1000 only sequences flight plan waypoints when automatic sequencing is enabled (i.e., no “OBS” or
‘SUSP’ annunciation). For automatic sequencing to occur, the aircraft must also cross the “bisector” of the turn
being navigated. The bisector is a line passing through the waypoint common to two flight plan legs at an
equal angle from each leg.
HOW CAN A WAYPOINT BE SKIPPED IN AN APPROACH, A DEPARTURE, OR AN ARRIVAL?
The G1000 allows the pilot to manually select any approach, departure, or arrival leg as the active leg of
the flight plan. This procedure is performed on the MFD from the Active Flight Plan Page by highlighting the
desired waypoint and selecting the ACT LEG Softkey then the ENT Key to approve the selection. The GPS
then provides navigation along the selected flight plan leg.
WHEN DOES TURN ANTICIPATION BEGIN?
The G1000 smooths adjacent leg transitions based on a normal 15° bank angle (with the ability to roll up to
30°) and provides three pilot cues for turn anticipation:
• A waypoint alert (‘Next DTK ###° in # seconds’ or ‘Next HDG ###° in # seconds’) appears on the PFD 10
seconds before the turn point and flashes as it counts down to zero.
• A flashing turn advisory (‘Turn [right/left] to ###° in # seconds’) appears on the PFD 10 seconds before the
turn and flashes as it counts down to zero. ‘Turn [right/left] to ###° now’ or ‘Next [DTK/HDG] to ###° now’
is displayed when the pilot is to begin the turn and the HSI (GPS mode) automatically sequences to the next
DTK or HDG value.
• The To/From indicator on the HSI flips momentarily to indicate that the midpoint of the turn has been
crossed

APPENDIX D
WHEN DOES THE CDI SCALE CHANGE?
When 30 nm from the destination, the G1000 begins a smooth CDI scale transition from 5.0 nm (en route
mode) to 1.0 nm (terminal mode). When 2 nm from the FAF during an active approach, the CDI scale
transitions to 0.3 nm (approach mode). When executing a missed approach, the CDI can be returned to the
1.0 nm scale by selecting the SUSP Softkey. The CDI is also set to 1.0 nm (terminal mode) within 30 nm of
the departure airport.
WHY DOES THE HSI NOT RESPOND LIKE A VOR WHEN OBS MODE IS ACTIVE?
Unlike a VOR, the CDI scale used on GPS equipment is based on the crosstrack distance to the desired
course, not on the angular relationship to the destination. Therefore, the CDI deflection on the GPS is constant
regardless of the distance to the destination and does not become less sensitive when further away from the
destination.
WHAT IS THE CORRECT MISSED APPROACH PROCEDURE? HOW IS THE MISSED APPROACH HOLDING POINT SELECTED?
To comply with TSO specifications, the G1000 does not automatically sequence past the MAP. The first
waypoint in the missed approach procedure becomes the active waypoint when the SUSP Softkey is selected
after crossing the MAP. All published missed approach procedures must be followed, as indicated on the
approach plate.
To execute the missed approach procedure prior to the MAP (not recommended), select the Active Flight Plan
Page and use the ACT LEG Softkey to activate the missed approach portion of the procedure.
AFTER A MISSED APPROACH, HOW CAN THE SAME APPROACH BE RE-SELECTED? HOW CAN A NEW APPROACH BE
ACTIVATED?
NOTE: Do not attempt to reactivate the current approach prior to crossing the missed approach point
(MAP). If an attempt to do so is made, an alert message “Are you sure you want to discontinue the current
approach?” appears. The G1000 directs the pilot back to the transition waypoint and does not take into
consideration any missed approach procedures, if the current approach is reactivated.
After flying the missed approach procedure, the pilot may reactivate the same approach for another attempt by
pressing the PROC Key. Once the clearance is given for another attempt, activate the approach by highlighting
‘ACTIVATE APPROACH’ using the large FMS Knob and pressing the ENT Key. The G1000 provides navigation
along the desired course to the waypoint and rejoins the approach in sequence from that point.
To activate a new approach for the same airport, select the new procedure by pressing the PROC Key. Choose
‘SELECT APPROACH’, select the desired approach from the list shown, and press the ENT Key. Select the
desired transition, then activate the approach using the ENT Key.
To activate a new approach to a different airport, press the Direct-to Key and select the desired airport using
the FMS Knobs. Press the ENT Key to accept the selected airport, then follow the steps in the preceding
paragraph to select an approach for the new airport.

GENERAL TIS INFORMATION
INTRODUCTION
NOTE: Aircraft without an operating transponder are invisible to TIS.
The Traffic Information Service (TIS) provides traffic advisory information to non-TAS/TCAS-equipped
aircraft. TIS is a ground-based service providing the relative locations of all ATCRBS Mode-A and Mode-C
transponder equipped aircraft within a specified service volume. The TIS ground sensor uses real-time track
reports to generate traffic notification. The G1000 System displays TIS traffic information on the Traffic Map
Page of the MFD. TIS information may also be displayed for overlay on the MFD Navigation Map Page, as
well as on the PFD Inset Map. Surveillance data includes all transponder-equipped aircraft within the coverage
volume. The G1000 System displays up to eight traffic targets within a 7.5 nm radius, from 3,000 feet below,
to 3,500 feet above the requesting aircraft.
TIS VS. TAS/TCAS
The main difference between the Traffic Information System (TIS) and Traffic Advisory (TAS) or Traffic
Collision Avoidance Systems (TCAS) is the source of surveillance data. TAS/TCAS uses an airborne interrogator
with a half-second update rate, while TIS utilizes the terminal Mode-S ground interrogator and accompanying
data link to provide a five-second update rate. TIS and TAS/TCAS have similar ranges.
TIS LIMITATIONS
NOTE: TIS is not intended to be used as a collision avoidance system and does not relieve the pilot of the
responsibility to “see and avoid” other aircraft. TIS shall not be used for avoidance maneuvers during
instrument meteorological conditions (IMC) or when there is no visual contact with the intruder aircraft.
NOTE: Refer to the TIS Limitations section of the Aeronautical Information Manual (AIM) for a more
comprehensive explanation.
TIS relies on surveillance of the Mode-S radar system, which is a “secondary surveillance” radar system
similar to that used by ATCRBS. Many limitations are inherent in secondary radar surveillance. Information
provided by TIS is neither better nor more accurate than the information used by ATC. TIS is intended only
to assist in visual acquisition of other aircraft in visual meteorological conditions (VMC). While TIS is a useful
aid for visual traffic avoidance, system limitations must be considered to ensure proper use. No recommended
avoidance maneuvers are given, nor authorized, as a direct result of a TIS intruder display or TIS advisory.
• TIS operation may be intermittent during turns or other maneuvering.
• TIS is dependent on two-way, line-of-sight communications between the aircraft and the Mode-S radar
antenna. Whenever the structure of the aircraft comes between the transponder antenna and the groundbased radar antenna, the signal may be temporarily interrupted.
• Other limitations and anomalies associated with TIS are described in the AIM.

APPENDIX E
WARNING: Garmin is not responsible for Mode S geographical coverage. Operation of the ground stations
is the responsibility of the FAA. Refer to the AIM for a Terminal Mode S radar site map.
NOTE: TIS is unavailable at low altitudes in many areas of the United States. This is often the case in
mountainous regions.
TIS information is collected during a single radar sweep. Collected information is then sent through the
Mode S uplink on the next radar sweep. Because of this, the surveillance information is approximately five
seconds old. TIS ground station tracking software uses prediction algorithms to compensate for this delay.
These algorithms use track history data to calculate expected intruder positions consistent with the time of
display. Occasionally, aircraft maneuvering may cause variations in this calculation and create slight errors on
the Traffic Map Page. Errors affect relative bearing information and target track vector. This can cause a delay in
the displayed intruder information. However, intruder distance and altitude typically remain relatively accurate
and may be used to assist in spotting traffic.
The following errors are common examples:
• When the client or intruder aircraft maneuvers excessively or abruptly, the tracking algorithm may report
incorrect horizontal position until the maneuvering aircraft stabilizes.
• When a rapidly closing intruder is on a course that intercepts the client aircraft course at a shallow angle
(either overtaking or head-on) and either aircraft abruptly changes course within 0.25 nm, TIS may display
the intruder aircraft on the incorrect side of the client aircraft.
These are rare occurrences and are typically resolved within a few radar sweeps once the client/intruder
aircraft course stabilizes.
Pilots using TIS can provide valuable assistance in the correction of malfunctions by reporting observations
of undesirable performance. Reports should identify the time of observation, location, type and identity of
the aircraft, and describe the condition observed. Reports should also include the type of transponder and
transponder software version. Since TIS performance is monitored by maintenance personnel, not ATC,
malfunctions should be reported in the following ways:
• By telephone to the nearest Flight Service Station (FSS) facility
• By FAA Form 8000-7, Safety Improvement Report (postage-paid card can be obtained at FAA FSSs, General
Aviation District Offices, Flight Standards District Offices, and General Aviation Fixed Base Operators)
