摘要 |
There is provided a method for automatically measuring the takeoff/landing time of an aircraft which has been performed conventionally by human visual observation. Furthermore, there is provided an aircraft takeoff/landing management method using the method. An ACAS signal transmitted from an aircraft transponder is received and a vertical status code contained in the signal or a barometric altimeter indication value change is used to detect/measure a takeoff/landing time. Moreover, the signal is classified according to the aircraft unique identifier contained in the signal. Thus, takeoff/landing information on a plenty of aircraft can be acquired and managed.
