Afcs Pre-Flight Actions - Garmin G3X Pilot's Manual

AFCS
The G3X can also communicate with various third-party autopilot units. With an
appropriate third-party autopilot installed and the G3X Integrated Autopilot Interface
is configured (refer to the G3X Installation Manual), the G3X issues pitch and roll
steering commands to the autopilot unit. The autopilot unit is then responsible for
moving the flight controls.
This section contains the following terminology:
• Autopilot Unit: Refers to the third-party autopilot box.
• Integrated Autopilot Interface: Refers to the functionality available when the
Autopilot Unit and the G3X are working together.
NOTE: Refer to the G3X Installation Manual and the third-party autopilot
vendor documentation for information on installing and configuring the G3X
Integrated Autopilot Interface.
NOTE: This section covers the operation of the G3X when configured with
specific third-party autopilot models. Refer to the third-party autopilot vendor
documentation for standalone autopilot functionality and control features.
NOTE: In a multiple display configuration, the autopilot unit is connected to
a single GDU (most likely the PFD). In the event that the GDU connected to
the autopilot unit fails, the Integrated Autopilot Interface capability will be
lost; however, the autopilot unit will retain any standalone functionality it
may support on its own.

AFCS PRE-FLIGHT ACTIONS

To ensure that the Automatic Flight Control System (AFCS) is operating properly
prior to flight, perform the following Garmin recommended preflight checks.
Before takeoff checklist - Garmin autopilot with GSA 28 servos, no
mode controller:
1) Autopilot - ENGAGE (using AP/CWS button)
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)
