PFT step 10: Updating servo RTC
This step is setting the system time in the servos to by the same time as the GIA system time.
This step should never fail.
PFT step 11: Verify servo PFT status
This step is checking to make sure the servos have all passed their own PFT.
If this step fails, please proceed to servo PFT explanation below.
PFT step 12: Verify AP disconnect enabled
This step is checking to make sure GIA1, GIA2, and all servos have are connected to a 28 volt
AP disconnect.
If this step fails, make sure the AP disconnect input to GIA1, GIA2, and all servos is connected
and registering 28 volts. Make sure the AP disconnect switch has been installed in the aircraft.
Make sure no one is holding the AP disconnect switch down on the yoke.
PFT step 13: Verify servo validity
This step is checking to make sure all the Servos are up and communicating with valid data to
the GIA in TDM mode.
If this step fails, then make sure all Servos are turned on and communicating by checking for
green boxes on the GFC configuration page.
PFT step 14: Verify servo enable/disable discrete input
This step is checking the servo discrete inputs. It is not used on King Air.
PFT step 15: Verify cross GIA PFT is completed
This step is checking to make sure the other GIA is also on step 15 of its PFT.
If this step fails, try cycling power on GIA1, GIA2, and all servos. If PFT still fails at step 15 then
you will need to go check the PFT status of the other GIA and see what step it is failing. NOTE:
The PFT status is communicated between GIA1 and GIA2 using HSDB. As a result, both the
PFD and MFD must be powered for this state to pass.
PFT step 16: PFT completed
The PFT has successfully completed.
PFT step 17: PFT failed
The PFT has failed.
