The invention provides an FOQA monitoring false alarm suppression method. The method comprises the following steps: (1) calculating takeoff and landing moments; (2) calculating an average taxiing direction during takeoff and landing; (3) calculating the transverse movement distance per second before takeoff and after landing by using a differential method; (4) summing up the transverse movement distances per second to obtain the transverse distance relative to the runway at each moment; and (5) suppressing the false alarm in the FOQA by using the transverse movement distance. According to the method, the QAR data is used for calculating the transverse distance of the aircraft relative to the runway during takeoff and landing, the problem that in traditional FOQA alarm logic, a ground operation item is prone to false alarm due to boundary condition setting, airport requirements and other factors is effectively solved, and FOQA monitoring and other flight data analysis work are powerfully supported.
本发明提供一种FOQA监控虚警抑制方法,该方法包括:(1)计算起飞与着陆时刻;(2)计算起飞与着陆时的平均滑跑方向;(3)利用微分法计算起飞前与着陆后每秒的横向移动距离;(4)将每秒的横向移动距离加总,得到每一时刻相对跑道的横向距离;(5)使用横向移动距离,对FOQA中的虚警进行抑制。本发明利用QAR数据对飞机在起飞与着陆时相对跑道的横向距离进行计算,有效避免了传统FOQA告警逻辑中地面操作项容易因为边界条件设置、机场要求等因素造成的虚警问题,有力支持了FOQA监控等飞行数据分析工作。
