5.5.3 GIA Fault Log Descriptions
The section is meant to help determine why the GFC 700 has failed the pre-flight test. A failed pre-flight
test is indicated by a
indication in the AFCS Annunciation field. There are 16 steps to the
GFC 700 pre-flight test.
NOTE
A thorough understanding of the G1000 system in Configuration mode is recommended
before you start this procedure.
1. Start the G1000 in Configuration mode.
2. Use the FMS knob on the PFD to go to the Diagnostics Terminal page in the System group. This
page allows the technician to view maintenance logs associated with the GFC 700.
3. Using the FMS knob choose GIA 1 or GIA 2 in the LRU window.
4. Using the FMS knob choose VIEW MAINTENANCE LOG in the COMMAND window.
5. Press the ENT key.
6. Scroll through the OUTPUT list by pressing the OUTPUT softkey.
The GIA will log any of the following faults:
FCS Task not started: Bad gains
The FCS task has not started because the gains are not present or have been corrupted.
Reload the gain files to correct.
FCS Task not started: Gain structure out of range
The FCS task has not started because the gains are not compatible with the GIA software.
Reload the gain files to correct.
PFT FAIL: Timeout, <STEP>
Pre-flight test has failed because the specified step has not passed in the allotted time. See the GIA
pre-flight steps for a description of the possible values for <STEP> on the failed GIA and corrective
actions.
PFT FAIL: Cross GIA Failed, State: <STEP>
Pre-flight test has failed on opposite GIA. <STEP> specifies the pre-flight test step on selected GIA
that was in progress when the pre-flight test failed on the opposite GIA. See the GIA pre-flight steps
for a description of the possible values for <STEP> on the failed GIA and corrective actions.
