Abstract:

A track estimation method is presented which utilizes aircraft performance parameters based on flight plan for general aviation aircraft. The track estimation method employs three-stage flight model which includes climb,cruise and descent. Then the aircraft performance parameters in different flight levels are employed to calculate durations in climb and descent stage. A track points pairing method is also presented,which could be utilized in track estimation updating. The method is implemented by C++ and applied in general aviation flight data processing system successfully.

Key words: general aviation, flight plan, track estimation, track pairing
