Abstract:

For the analysis after flight, flight trajectories are  gotten using civil flight airborne data by integral approximation and are corrected by latitude and longitude transformation. Geometric attitude is used as flight trajectories attitude for the first time in flight playback. For dynamic flight playback in threedimensional scenes, a flight playback program is  designed, especially displaying the change of flight trajectories and gestures. The program demonstration indicates that this method can make the flight playback precisely and fluently, which is easytoobserve and easytoanalyze, and can be used to flight inspection and research after flight.
