Abstract:
PURPOSE: To monitor sensor data in a flight-data recorder for recording data from several sensors attached respectively to several parts of the air-frame of an aircraft during flight test or during starting test just before flight.
CONSTITUTION: When a control switch 5 is manipulated, a signal adapted to be stored in a memory in a flight-data recorder is made to branch off, and is taken through a recorder data input circuit 3 for comparing the signal with reference data previously stored in a reference data memory 9 while the condition is displayed on an LCD display part 4. This device incorporates a battery 10 and is set in a small-sized casing so as to be portable brought into an aircraft. With this arrangement, it is possible to enhance the safety for flight.
