the Airplane Flight Manual (AFM) for recommended pilot actions.
COMPARATOR ANNUNCIATIONS
The Comparator monitors critical values generated by redundant sensors. If differences in the sensors
exceed a specified amount, this discrepency will be annunciated in the Comparator Window as a ‘MISCOMP’
(miscompare) as seen in Figure A-1. If one or both of the sensed values are unavailable, it will be annunciated
as a ‘NO COMP’ (no compare). The following is a list of the possible annunciations:

ALT MISCOMP
Difference in altitude sensors is > 200 ft.
IAS MISCOMP
If both airspeed sensors detect < 35 kts, this is inhibited.
If either airspeed sensor detects > 35 kts, and the difference in sensors is > 10 kts.
If either airspeed sensor detects > 80 kts, and the difference in sensors is > 7 kts.
HDG MISCOMP Difference in heading sensors is > 6º.
PIT MISCOMP Difference in pitch sensors is > 5º.
ROLL MISCOMP Difference in roll sensors is > 6º.
ALT NO COMP No data from one or both altitude sensors.
IAS NO COMP No data from one or both airspeed sensors.
HDG NO COMP No data from one or both heading sensors.
PIT MISCOMP No data from one or both pitch sensors.
ROLL MISCOMP No data from one or both roll sensors..
