摘要
给出了通航飞机基于飞机性能参数的飞行计划航迹估算实现方法。进行航迹估算时,建立基本的爬升、巡航、下降三阶段飞行模型,分阶段计算,爬升、下降阶段根据飞机在不同高度层的性能参数进行估算,最终得到飞机飞过各个位置点的时间。飞机起飞后会进行估算的更新,此时给出了一种航迹配对的方法。对上述方法采用C++编程予以实现,用于通用航空飞行计划处理子系统中,结果满足系统需求。
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.
