Comparison monitoring between two units detects a fault by
Answer: D
Correct answer: Flagging when their outputs differ by more than a threshold
Comparison monitoring works by differencing the two units' outputs and raising a warning when the difference exceeds a preset threshold. The threshold is set above the normal spread of two healthy units and below the smallest error that would matter operationally.
With only two units the monitor can say that one of them is wrong but not which, so the usual response is to flag both and require the crew to judge against another source. Internal temperature and supply voltage are built-in test parameters rather than the comparison itself, and the air data computer measures quite different quantities.
