The Flight Hour Meter is installed whenever actual flying time has to be recorded, primarily in training and charter aircraft. This instrument should not be missing in aircraft operated by clubs or by private individuals, where it permits a check of inspection intervals.
The Flight Hour Meter has an electrically driven counter mechanism and the readings are in hours and minutes. It is connected to the aircraft's total pressure sensor and automatically switches on when airspeed increases to 60 km/h. This ensures that actual flying time only is recorded, while secondary times for take off and landing are ignored.
Once installed, the plug can be sealed to prevent tampering.
