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 74B 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Do not use outdated database information.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 Pilots using any outdated database do so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:

XM 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.

WARNING:

The Garmin G1000, as installed in the Cessna Citation Mustang aircraft, has a very high degree of
functional integrity. However, the pilot must recognize that providing monitoring and/or self-test capability
for all conceivable system failures is not practical. Although unlikely, it may be possible for erroneous
operation to occur without a fault indication shown by the G1000. It is thus the responsibility of the pilot
to detect such an occurrence by means of cross-checking with all redundant or correlated information
available in the cockpit.

WARNING:

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

WARNINGS, CAUTIONS, AND NOTES

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 and the Cessna Citation Mustang Airplane Flight Manual. 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:

a thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms, and the

The illustrations in this guide are only examples. Never use the G1000 to attempt to penetrate

Aeronautical

Information
Manual (AIM) recommend avoiding “by at least 20 miles any thunderstorm identified as severe or giving an
intense radar echo.”

CAUTION:

The GDU 1040A PFDs and GDU 1500 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:

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

NOTE:

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

NOTE:

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.com/prop65.

NOTE

:

Interference from GPS repeaters operating inside nearby hangars can cause an intermittent loss of
attitude and heading displays while the aircraft is on the ground. Moving the aircraft more than 100 yards
away from the source of the interference should alleviate the condition.

NOTE:

to local, state, or federal laws. For more information, refer to our website at www.garmin.com/aboutGarmin/

SYSTEM OVERVIEW

NOTE:

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

and emergency power supply operation.

The G1000 system is integrated with the aircraft electrical system and receives power directly from electrical
busses. The G1000 PFDs, 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 1-7. All system annunciations
should disappear typically within one minute of power-up. Upon power-up, key annunciator lights also become
momentarily illuminated on the audio panels, the control units and the display bezels.

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 one minute of power-up. The AHRS can align itself both
while taxiing and during level flight.

When the MFD powers up (Figure 1-8), the MFD Power-up Page 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

• Chartview database information

• Safe Taxi database information

Current database information includes the 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

SYSTEM OVERVIEW

1.6 SYSTEM OPERATION

The displays are connected together via a single Ethernet bus, thus allowing for high-speed communication.
As shown in Figure 1-1, each GIA 63W is connected to the on-side PFD. This section discusses the normal and
reversionary modes of operation as well as the various AHRS modes of the G1000 system.

NORMAL OPERATION

PFD

In normal mode, the PFD presents graphical flight instrumentation (attitude, heading, airspeed, altitude
and vertical speed), thereby replacing the traditional flight instrument cluster. The PFD also offers control for
COM and NAV frequency selection.

MFD

In normal mode, the right portion of the MFD displays a full-color moving map with navigation information,
while the left portion of the MFD is dedicated to the Engine Indication and Crew Alerting System (EICAS).

Figure 1

-9 gives an example of the G1000 displays in normal mode.

Figure 1-9 Normal Operation

REVERSIONARY MODE

NOTE:

Reversionary mode is a mode of operation in which all important flight information is presented identically

on at least one of the remaining displays (see Figure 1-10). Transition to reversionary mode should be
straightforward for the pilot, for flight parameters are presented in the same format as in normal mode.

The G1000 system alerts the pilot when backup paths are utilized by the LRUs. Refer to the Appendices

for further information regarding system-specific alerts.

Should the connection between a PFD and the on-side GIA 63W become inoperative, the on-side GIA 63W

can no longer communicate with the remaining PFD (refer to Figure 1-

1). As a result, the NAV and COM

In addition to using internal sensors, the GRS 77 AHRS uses GPS information, magnetic field data and air

data to assist in attitude/heading calculations. In normal mode, the AHRS relies upon GPS and magnetic
field measurements. If either of these external measurements is unavailable or invalid, the AHRS uses air
data information for attitude determination. Four AHRS modes of operation are available (see Figure 1-13)
and depend upon the combination of available sensor inputs. Loss of air data, GPS, or magnetometer sensor
inputs is communicated to the pilot by message advisory alerts.

1-18

Figure 1-13 AHRS Operation

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.

The G1000 system provides two sources of GPS information. If a single GPS receiver fails, or if the

information provided from one of the GPS receivers is unreliable, the AHRS seamlessly transitions to using the
other GPS receiver. An alert message informs the pilot of the use of the backup GPS path. If both GPS inputs
fail, the AHRS continues to operate in reversionary No-GPS mode so long as the air data and magnetometer
inputs are available and valid.

Garmin G1000 Pilot’s Guide for the Cessna Citation Mustang

190-00494-01 Rev. B

SYSTEM OVERVIEW

AIR DATA INPUT FAILURE

A failure of the air data input has no effect on AHRS output while AHRS is operating in normal mode. A
failure of the air data input while the AHRS is operating in reversionary No-GPS mode results in invalid
attitude and heading information on the PFD (as indicated by red “X” flags).

MAGNETOMETER FAILURE

If the magnetometer input fails, the AHRS transitions to one of the reversionary No-Magnetometer modes
and continues to output valid attitude information. However, if the aircraft is airborne, the heading output
on the PFD does become invalid (as indicated by a red “X”).

G1000 SYSTEM ANNUNCIATIONS

NOTE:

For a detailed description of all annunciations and alerts, refer to Appendix A. Refer to the Airplane

Flight Manual (AFM) 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 1-14 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.

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.
