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Do not use outdated database information.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 Pilots using any outdated database do so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:

WARNING:

For safety reasons, G1000 operational procedures must be learned on the ground.

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.”

WARNING:

Because of anomalies in the earth’s magnetic field, operating the G1000 within the following
areas could result in loss of reliable attitude and heading indications. North of 70° North latitude and south
of 70° South latitude. An area north of 65° North latitude between longitude 75º West and 120º West. An
area south of 55° South latitude between longitude 120º East and 165º East.

CAUTION:

The PFD and 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.

WARNINGS, CAUTIONS, AND NOTES

NOTE: When using Stormscope, there are several atmospheric phenomena in addition to nearby thunderstorms
that can cause isolated discharge points in the strike display mode. However, clusters of two or more discharge
points in the strike display mode do indicate thunderstorm activity if these points reappear after the screen has
been cleared.

NOTE: All visual depictions contained within this document, including screen images of the G1000 panel and displays,
are subject to change and may not reflect the most current G1000 system and aviation databases. Depictions of
equipment may differ slightly from the actual equipment.

NOTE: This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
this device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.

NOTE: The GDU 1040 PFD/MFD may require a warm-up time of up to 30 minutes when exposed to -40˚C for an
extended period. A warm-up time of up to 15 minutes may be required when exposed to -30˚C for an extended

period.

NOTE: This product, its packaging, and its components contain chemicals known to the State of California to cause
cancer, birth defects, or reproductive harm. This notice is being provided in accordance with California’s Proposition

65. If you have any questions or would like additional information, please refer to our web site at www.garmin.

display is configured as a PFD and the right display is configured as an MFD. Both GDU 1044Bs 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. Systems using the Honeywell KAP 140 Autopilot System use the
GDU 1040, which employs the same features as the GDU 1044B without the controls for the Garmin GFC 700
Automatic Flight Control System (AFCS)

– The GDU 1044B features a 10.4-inch LCD display with 1024 x 768 resolution. The left

1.5 SYSTEM POWER-UP

SYSTEM OVERVIEW

NOTE:

See the Aircraft Flight Manual (AFM) for specific procedures concerning avionics power application

and emergency power supply operation.

NOTE:

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

Refer to Appendix A for system-specific annunciations and alerts.

• 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.

Each IAU is

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 Flight Management
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:

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.

1-14

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.

AHRS OPERATION

NOTE:

NOTE:

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).

Refer to Appendix A for specific AHRS alert information.

Aggressive maneuvering while AHRS is not operating normally may degrade AHRS accuracy.

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

G1000 SYSTEM ANNUNCIATIONS

SYSTEM OVERVIEW

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.
