摘　　要：对航空器着陆阶段运行轨迹分析是客观评价飞行员技术水平与航司运行品质的重要手段,在保障航空器安全高效运行等方面具有重要意义。通过对QAR数据中经纬度参数在地图软件中打点分析发现,航空器在跑道上减速滑行阶段轨迹出现明显的曲折、错位与偏移现象。采用S⁃G滤波算法,构建航空器着陆阶段轨迹修正模型,对航迹进行修正处理。结果表明,S⁃G滤波算法修正模型可对原始航迹进行良好修正。Analyzing the operational trajectory of aircraft during landing is an important means to objectively evaluate the tech⁃nical level of pilots and the operational quality of airlines,and is of great significance in ensuring the safe and efficient operation of aircraft.Through dot analysis of the longitude and latitude parameters in QAR data in map software,it was found that the trajectory of the aircraft during deceleration and taxiing on the runway showed significant twists,dislocations,and deviations.This article uses the S⁃G filtering algorithm to construct a trajectory correction model for the aircraft landing phase,and performs trajectory cor⁃rection processing.The results indicate that the S⁃G filtering algorithm can effectively correct the original trajectory by modifying the model.
