NOTE
ADS-B technology improves situational awareness and flight safety. A
Garmin transponder with ADS-B capabilities will automatically transmit
position, velocity, and heading information to other aircraft and ground
stations. The current air traffic control system depends on a transponder
request for pertinent aircraft information, whereas ADS-B provides
automatic transmission of aircraft information without a request.
2.2.9 GRS 79 Altitude and Heading Reference System
The Attitude and Heading Reference System (AHRS) provides aircraft attitude and
heading information to both displays and both GIAs. The AHRS contains advanced
sensors (including accelerometers and rate sensors) that interface with the
Magnetometer to obtain magnetic field information, with the ADC to obtain air data, and
with both GIAs to obtain GPS information.
2.2.10 GDC 72 Air Data Computer
The Air Data Computer (ADC) 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 system, and it communicates with both GIAs, the PFDs, the MFD, and
the AHRS. It also interfaces directly with the OAT probe.
2.2.11 GMU 44/GMU 44B Magnetometer
The GMU 44(B) magnetometer measures the magnitude of the local magnetic field in
three axes. It also measures its own internal temperature and its two-axis tilt angles. The
GMU 44(B) relays all this information to the GRS 79 AHRS unit. The GMU 44(B) uses
magneto-resistive sensors, an inclinometer, and a temperature sensor to perform its
measurements. The sensor readings are converted from their original analog voltage
format into digital format. The GMU 44(B) has a single RS-232 input for code upload and
testing. This input is not active in normal operation.
The GMU 44(B) is a sensitive instrument that requires careful mounting. Specific
guidelines regarding vibration, mounting rigidity, accuracy of orientation (relative to
aircraft structure), and placement position (relative to aircraft structure), and magnetic
disturbances must be observed. Refer to the GRS 79 AHRS Installation Manual, Garmin
P/N 190-01852-00, for details.
2.2.12 GTP 59 Outside Air Temperature Probe
Each of the GTP 59 OAT probes provides outside air temperature data for use by the
associated GDC 72 Air Data Computer.
