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.%为了便于飞行事后分析,根据民用客机机载数据,本文采用了轨迹积分法重现飞行轨迹并用经纬度转换法进行校正,首次利用几何高度表示飞行轨迹中的高度.为实现在三维场景中进行飞行动态回放研究,设计了三维飞行回放程序,重点设计了飞行轨迹以及姿态的变化在三维场景中的展示.通过程序演示表明；该方法能正确流畅地对飞行进行事后回放演练,有利于观察分析,可用于飞行事后调查与研究.
