1.8 G1000 AVIONICS SYSTEM
1. The G1000 Integrated Avionics System is a fully integrated flight, engine,
communication, navigation and surveillance instrumentation system. The system
consists of a Primary Flight Display (PFD), Multi-Function Display (MFD), audio panel,
Air Data Computer (ADC), Attitude and Heading Reference System (AHRS), engine
sensors and processing unit (GEA), and integrated avionics (GIA) containing VHF
communications, VHF navigation, and GPS (Global Positioning System).
2. The primary function of the PFD is to provide attitude, heading, air data, navigation,
and alerting information to the pilot. The PFD may also be used for flight planning.
The primary function of the MFD is to provide engine information, mapping, terrain
information, and for flight planning. The audio panel is used for selection of radios for
transmitting and listening, intercom functions, and marker beacon functions.
3. The primary function of the VHF Communication portion of the G1000 is to enable
external radio communication. The primary function of the VOR/ILS Receiver portion
of the equipment is to receive and demodulate VOR, Localizer, and Glide Slope signals.
The primary function of the GPS portion of the system is to acquire signals from the
GPS satellites, recover orbital data, make range and Doppler measurements, and
process this information in real-time to obtain the user’s position, velocity, and time.
4. Provided a Garmin G1000 GPS receiver is receiving adequate usable signals, it has
been demonstrated capable of and has been shown to meet the accuracy specifications
for:
(a) VFR/IFR enroute, oceanic, terminal, and non-precision instrument approach (GPS,
Loran-C, VOR, VOR-DME, TACAN, NDB, NDB-DME, RNAV) operation within the
U.S. National Airspace System in accordance with AC 20-138A.
