GMU 44

The GMU 44 magnetometer senses the earth' s magnetic field. Data is sent
to the GRS 77H AHRS for processing to determine aircraft magnetic heading.
This unit receives power directly from the GRS 77H and communicates with the
GRS 77H using a RS-485 digital interface.
1.1.1.5 GTP 59
The GTP 59 temperature probe provides Outside Air Temperature (OAT)
data to the GDC 74H.
1.1.1.6

Garmin Navigator Interface

The G500H system requires connection to at least one external Garmin
WAAS GPS navigator, such as the 400W/500W series, GTN 600/700 series, or
GNS 480.
1.1.1.7

GEA 71

The GEA 71 receives and processes signals from the engine and airframe
sensors.
