PRMTR: <PARAMETER> MODE:<MODE> Parameter lost
The mode specified by
<MODE>
has been disengaged because the parameter specified by
<PARAMETER>
has become invalid. The following is a list of some of the possible values for
<PARAMETER>:
a. AD TDM Comm Valid:
The specified mode has been disengaged because communication
with the servos, via the Time Division Multiplexer protocol, has been lost.
b. AP Pitch MET not stuck:
The specified mode has been disengaged due to a stuck pitch
MET switch.
Check the MET (trim) switches for proper identification.

GIA Pre-Flight Test Steps
PFT step 0: System initialization, verify GFC powered
This step is checking to make sure the GFC is powered up. It checks to make sure the GIA AP
disconnect input is connected to 28 volts, and makes sure the Servos are up and communicating.
If this step fails, make sure the GIA is connected to AP disconnect by using the GFC configuration page.
Also make sure all configured Servos are communicating by checking for Servo product data in
configuration mode.
PFT step 1: System initialization, verify GIA audio is valid.
This step is checking to make sure that the GIA audio region has been loaded and configured.
If this step fails, load GIA audio region and audio configuration.
PFT step 2: System initialization, verify required servos are configured
This step is checking to make sure the current Servo configuration matches the Servo configuration
specified in the certification gain file.
If this step fails, then make sure the Servo configuration on the GFC configuration page matches the
Servo configuration specified in the configuration gain (.cgn) file.
PFT step 3: System initialization, verify selected side
This step is checking to make sure the PFD1 is online and sending the selected AFCS side data over
HSDB to GIA1.
If this step fails, then make sure the PFD is powered up and there is an Ethernet connection from the PFD
to the GIA.
PFT step 4: System initialization, verify AHRS monitor
This step is checking to make sure the AHRS monitor is valid and not reporting an AHRS failure. NOTE:
AHRS monitor will be assumed valid if on the ground.
If this step fails, then make sure the AHRS and ADC is powered up and sending valid attitude data to the
G1000.
