The monitor processor contains the logs that are found in these processors:
2 – Pitch Servo
4 – Roll Servo
6 - Yaw
8 – Pitch Trim Servo
There are two main groupings of faults that can occur in the monitor processor.
The first grouping of faults can occur during the GSA unit pre-flight test (PFT). If there is
a fault during PFT the unit will not be able to transition to normal mode and the only way
to clear this state would be to cycle unit power. The second grouping of faults can occur
during normal mode. These faults generally cause a disconnect of power to the GSA and
report that a fault has occurred to the GIA.
