5.6 Autopilot Operation
The G600 is able to interface to certain autopilot systems to provide heading,
course, and navigation information in much the same way as a typical HSI.
Please refer to your particular autopilot manual for specific information and
operation instructions.
5.6.1 Autopilot Test
The 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 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.
