Discussion
In a triple installation the three heading outputs read 088.0, 088.3 and 093.5 degrees. The system continues to operate normally with no crew action.
What has the system done?
Answer: D
Correct answer: Excluded the outlier by median voting
The three readings are \( 088.0, 088.3 \) and \( 093.5 \) degrees. Two agree closely and the third is more than five degrees away, so median voting takes the middle value, \( 088.3 \), and the deviant unit is excluded automatically - which is why operation continues with no crew action.
Averaging would give about \( 089.9 \), nearly two degrees from where the healthy units agree, and would conceal the fault rather than isolate it. Selecting the highest value would select the faulty unit. Reversion to standby instruments is unnecessary while two good units remain.
