Autopilot (Ap); Gad 43 Attitude - Garmin G500 Reference Manual

The G500/G600 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.

GAD 43 Attitude

If the GAD 43 Adapter is providing attitude to the autopilot, test the disconnect
mechanism 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 and release the AP TEST soft key and verify that the autopilot
disconnects normally.
CAUTION: Do not use the autopilot if the AP TEST key fails to disconnect
the autopilot.
NOTE: If the AP TEST soft key is held for longer than one second, the test
will not run.
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.
