1.2.1 Autopilot Test
The optional GAD 43 Adapter provides attitude and heading information from
the Garmin GRS 77 Attitude and Heading Reference System to the autopilot.
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. Upon GDU 620 startup, the AP TEST soft key is available on the GDU 620
PFD.
2. Engage the AP while on the ground.
3. Press the AP TEST soft key and verify that the autopilot disconnects and an
autopilot disconnect tone is annunciated by the autopilot.
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.
