5.6 Autopilot Operation
The G500 is able to interface to certain autopilot systems to provide the
functions described in this section. Please refer to your particular Airplane Flight
Manual and autopilot documentation for specific information and operating
instructions.
5.6.1 GAD 43 Attitude
The GAD 43 Adapter may Optionally provide attitude information from the
Garmin GRS 77 Attitude and Heading Reference System to certain autopilots.
The GAD 43 has the ability to disconnect the autopilot if an error in the GAD 43
output or GRS 77 is detected. This disconnect mechanism must be tested prior
to each flight in the following manner:
1) Allow all avionics to complete power up and begin normal operation.
2) Engage the autopilot while on the ground.
3) Press the AP TEST soft key and verify that the autopilot disconnects normally.
CAUTION: Do not use the autopilot if the AP TEST does not disengage
the autopilot normally.
Autopilot Disconnect
When the GDU 620 attitude monitors have detected an AHRS malfunction,
or the inability to actively monitor the AHRS, a “Check Attitude” annunciation
will be displayed on the PFD and the autopilot will automatically disconnect.
NOTE: Only appears with the installation of an optional GAD 43
Adapter.
