7.10 GSA SOFTWARE INSTALLATION AND TESTING

Original Servo(s) Reinstalled:
If the removed servo(s) are re-installed (same serial numbers), no software loading is required.
This does not include units that were returned for repair as their software and configuration files
are deleted during the repair testing process.
New, Repaired or Exchange Servo(s) Installed:
If a new, repaired or exchange servo is installed; load the following files after removing the
Supplemental Database cards from the bottom slots of each display. Note which card was
removed from the MFD so it may be identified later for reinsertion in the MFD when software
and configuration loading is complete. It contains a FliteChart® or ChartView database which is
only used by the MFD. Reinstall all the cards after the software and configuration file loads are
complete.

7.10.1 GSA Testing
The following procedure will verify the proper operation of the GFC 700 AFCS. The technical
performing these checks must be thoroughly familiar with the GDC 700, refer to the applicable
Garmin G1000 Cockpit Reference Guide.
Autopilot Pre-Flight Test
The autopilot pre-flight test will run on every full autopilot power-on.
1. After powering up the system in normal mode, open the AP SERVOS circuit
breaker and reset. The AFCS will re-initiate the pre-flight test.
A red AFCS annunciation will be displayed until both GIAs, the AHRS,
and the autopilot servos are online.
2. Verify that a white 'PFT' annunciation is displayed on the PFD.
If the red AFCS annunciation remains on the PFD after the attitude comes up
and never switches to a white PFT annunciation, it indicates there is a failure
in the autopilot system preventing the preflight test from starting.
3. Upon successful completion of the test approximately 10 to 15 seconds, the
autopilot disconnect aural alert will sound and the annunciation will clear.
