WIPO Patent Application WO/2006/009127

Kind Code:

A1

Abstract:

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.
