. Refer to Section 4.3 of this manual to identify which type of GIA
63 (WAAS or Non-WAAS) is installed in the aircraft, and how to choose the correct WAAS or

After powering up the system in normal mode, open the AP SERVOS circuit breaker and rest.
The AFCS will re-initiate the pre-flight test.

Upon successful completion of the test (approximately 10 to 15 seconds), the autopilot disconnect
aural alert will sound and the annunciation will clear. Continue to Section 4.9.2.2.
NOTE
If the ‘PFT’ annunciation turns red, the test has failed and additional troubleshooting will have
to be performed prior to continuing the test.
