GFC Autopilot Ground Checks (if applicable)
The following procedure will verify the proper operation of the GFC 700 AFCS. The
technician performing these checks must be thoroughly familiar with the GFC 700 by
studying the G1000 Cockpit Reference Guide for the DA42NG.
3.8.1. Autopilot Pre-Flight Test
NOTE
The autopilot pre-flight test will run on every full airplane power-on.
1. Open the AUTOPILOT circuit breaker and reset. The AFCS will re-initiate the
pre-flight test.
NOTE
A red ‘AFCS’ (
) annunciation will be displayed until both
GIAs, the AHRS, and the autopilot servos are online. The red
‘AFCS’ annunciation will then be replaced by a white ‘PFT’
annunciation.
2. Verify that a white ‘PFT’ annunciation is displayed on the PFD, as shown in the
following figure.
