Model G58 Systems Description
Master relay. The COMM portion is protected by the 5-amp
COMM 2 circuit breaker and the other portions are protected
by the 5-amp INTEG AVION 2 circuit breaker. All four circuit
breakers are located on the Avionics Circuit Breaker Panel.

AIR DATA COMPUTER (ADC)

The Garmin Air Data Computer (GDC 74A) is connected to the
pitot and static air system and a Outside Air Temperature
(OAT) probe which is located on the bottom of the left wing.
The ADC provides OAT, airspeed, altitude, and vertical speed
for pilot displays and Flight Management System (FMS) func-
tions. The ADC is powered by the Left Bus and is protected by
the 5-amp ADC circuit breaker located on the Avionics Circuit
Breaker Panel. See pitot and static system description in this
section for more detailed information.

MAGNETOMETER (GMU)

The Garmin Magnetometer Unit (GMU 44) senses the Earth's
magnetic field and provides this information to the AHRS for
processing to determine the airplane's magnetic heading. The
GMU 44 is located in the left wing tip area and is powered by
the AHRS.
ATTITUDE AND HEADING REFERENCE SYSTEM
(AHRS)
The Garmin Attitude and Heading Reference System (GRS
77) provides pitch, roll, heading, and angular rate information
for pilot display and for FMS calculations. The AHRS is pow-
ered by the Left Bus and protected by a 5-amp circuit breaker
located on the Avionics Circuit Breaker Panel. See the Garmin
G1000 pilot's guide, Section 2, System Overview, for more
information.
