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WARNING: Do not use outdated database information.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 Pilots using any outdated database do so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

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.

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.

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.

•

GDL 90

(1) – A digital data link transceiver designed to transmit, receive and decode ADS-B messages. It

broadcasts aircraft position, velocity, projected track, altitude, and ﬂight identiﬁcation to other equipped aircraft

in the vicinity, as well as to FAA ground stations.

•

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.
