摘要
研究的目的是使管制员通过飞行管理计算机计算的结果来较精确地预测飞机到达各航路点的时间范围,在同时有多架飞机进场的情况下合理安排进近顺序。利用向量分解法,分析了飞机在有风情况下,特别是风向风速改变时地速的变化。给出了实时地速的计算方式,指出了通过调节两个航路点间加速度变化的位置来控制飞机到达下一航路点的时间,并给出了到达各航路点时间范围的计算方式。通过计算,管制员不仅可以推测出到达各航路点的高度及时间范围,避免飞行冲突,还能够安全有序的引导飞机按预计时间着陆,减少航班延误量。
The basic research purpose of this paper is that controller could forecast the range of arrival time of each waypoint accurately via the calculation of flight management system and arrange the approach order reasoningly when more than one plane approached at the same time.This paper make use of analytical method of vectors to analyse the change of ground speed,especially when the wind direction and wind speed changed.The calculation method of instantaneous ground speed is given.By way of modulate the position of acceleration change between tow waypoints to control the arrival time of the next waypoint.Given the calculation method of range of the arrival time.Calculated,the controller could speculate about the range of arrival time of each waypoint,avoid collision,and also control the plane landing at the expected time,reduce the rate of delay.
