The G3X Touch can also communicate with various non-Garmin autopilot units. With
an appropriate non-Garmin autopilot installed and the G3X Touch Analog Autopilot
Interface is configured (refer to the G3X Touch Installation Manual), the G3X Touch
issues course and heading information to the autopilot unit. The autopilot unit is then
responsible for moving the flight controls. The G3X Touch system will not display flight
director, modes, or annunciations for a non-Garmin autopilot system.
NOTE: Refer to the G3X Touch Installation Manual and the non-Garmin
autopilot vendor documentation for information on installing and configuring
the G3X Touch Analog Autopilot Interface.
NOTE: Refer to the non-Garmin autopilot vendor documentation for stand-
alone autopilot functionality and control features.
NOTE: When the autopilot is engaged with auto trim enabled, moving the
MET Switch will disengage the autopilot.
AFCS PRE-FLIGHT ACTIONS
To ensure the Automatic Flight Control System (AFCS) is operating properly prior to
flight, perform the following Garmin recommended preflight checks.
Before takeoff checklist - Garmin GFC 500:
1)
Autopilot - ENGAGE (using AP button, or AP button on mode controller)
2)
Flight controls - CHECK (verify autopilot can be overpowered in both pitch
and roll)
3)
AP DISC button - PRESS (verify autopilot disengages and audio alert is
heard)
4)
Verify yaw damper - OFF (if installed) (verify yaw damper disengages and
audio alert is heard)
5)
Flight director - SET FOR TAKEOFF (select TO or VS mode or push FD Button
to turn off the Flight Director)
6)
Flight controls - CHECK (verify autopilot servos are disengaged from pitch,
roll, and yaw controls, and all controls move freely)
