Control Panel Fail Status
This display is used to display the failure status of the selected control panel input if a
failure is detected and the control panel fail LED is illuminated.
The first line is used to display which of the control panels is selected, either A or B. The
failure is displayed on the second line, either “Invalid”, “Rate Failed”, or “No Data”.
For flight leg results all three faults can be displayed one per line starting on the second
line. Both Control Panel A and B pages can be displayed if failures occurred on each
while they were selected.
