Has there ever been...
Has there ever been a case where the standby compass was checked to be satisfactory at the gate, but then, during taxi, found to be 'broken'?
Or, has there ever been an accident attributed to a compass that 'broke' sometime after the 'gate check'?
I'm not sure what can break on a whiskey compass. If it's working at the gate, it should work the rest of the flight.
Anyone have any experiences with this...
