2.11.2.1 GIA Pre-Flight Test Steps
•
PFT Step 0: System initializing, verify GFC powered
This step checks to ensure the GFC is powered up.
Ensure the GIA is connected to the autopilot disconnect on the GFC Configuration page.
Ensure all configured servos are communicating on the System Status page.
•
PFT Step 1: System initializing, verify GIA audio is valid
This step checks to ensure the GIA audio region has been loaded and configured.
Load GIA audio files to correct.
•
PFT Step 2: System initializing, verify required servos are configured
This step checks to ensure the current servo configuration matches the servo configuration specified in the
certification gain file.
Reload the gain files to correct.
•
PFT Step 3: System initializing, verify selected side
This step checks to ensure the PFD is online and sending the selected AFCS side data over HSDB to the GIA.
Ensure the PFD is turned on.
Ensure the Ethernet connection from the PFD to the GIA is functioning.
•
PFT Step 4: System initializing, verify AHRS monitor
This step checks to ensure the AHRS monitor is valid and not reporting an AHRS failure. NOTE: AHRS
monitor will be assumed valid if on the ground.
Ensure the GRS 77 and GDC 74 are turned on and sending valid data.
•
PFT Step 5: System initializing, verify configured servos are valid
This step checks to ensure that none of the servos are reporting any type of failure. Note that trim servos will
report a failure on stuck MET switches.
Ensure MET switch is not stuck.
Cycle power on all servos.
•
PFT Step 6: System initializing, verify cross GIA valid
This step checks to ensure the cross-side GIA is online and communicating with all servos from ARINC 485
data lines. The cross-side GIA must also pass its AHRS monitoring.
Ensure both GIAs are online and communicating with all servos.
•
PFT Step 7: Verify cross GIA initialized
This step checks to ensure the cross-side GIA is initialized.
Cycle power on all servos and GIAs.
Ensure the PFD and MFD are turned on.
•
PFT Step 8: Verify servo type
This step checks to ensure the servos are correct type.
Verify servos are correct type.
