Abstract:
PURPOSE: To allow a pilot to predict a trouble in an airframe or an engine in view of an output signal which is delivered from one of several sensors attached respectively to several parts of the aircraft, and which is adapted to be recorded in a flight-data recorder.
CONSTITUTION: A detection signal from a sensor 1 which is adapted to be inputted to a control circuit 5 through a sensor interface circuit 4 so as to be stored in a memory 9 in a recording part 8, is made to branch off, and is delivered to a comparing circuit 6 which is adapted to transmit the signal a controller 11 provided in front of a pilot's seat through the intermediary of the control circuit 5, and accordingly, a king of a trouble and a degree of the same as a trouble are displayed on a display unit 12 in the controller 11 when the signal exceeds an associated one of preset warning values that are stored in a memory provided in a circuit, each for each sensor.
