System Overview - Garmin G300 for Cessna SkyCatcher Pilot's Manual

System Overview

• GSU 73
Garmin Sensor Unit sub-system for the G300 (Air Data Computer (ADC),
–
Engine/Airframe Unit, and the Attitude and Heading Reference System
(AHRS))
– ADC: Processes data from the pitot-static system and outside air
temperature (OAT) sensor.
– Engine/Airframe Unit: Receives and processes signals from the
engine and airframe sensors.
– AHRS: Provides aircraft attitude and heading information to the
PFD. The AHRS contains advanced sensors (including accelerom-
eters and rate sensors) and interfaces with the Magnetometer to
obtain magnetic field information, with the ADC to obtain air data,
and with the GDU to obtain GPS information. AHRS operation is
discussed later in this section.
