The invention belongs to the technical field of flight management systems, and particularly relates to an arc interception transition path calculation method. The method comprises the following steps: extracting flight plan information, calculating a turning direction according to an entry angle of a previous waypoint and a starting waypoint, a turning direction and a turning circle center information of a next RF leg (arc leg), calculating a turning radius according to a current ground speed and a maximum roll angle of an aircraft, further calculating a transition circle center and a transition arc tangent point through a geometrical relationship, and calculating a turning radius according to a turning radius. Therefore, the transition arc track is determined. According to the method, a smooth flight algorithm for transition to RF/AF flight segments is provided, the certainty and repeatability of the flight path are improved, and meanwhile the flight quality of an aerial carrier entering an arc flight route is improved.

    本发明属于飞行管理系统的技术领域,具体涉及一种圆弧截获过渡路径计算方法。该方法通过提取飞行计划信息,根据前一航路点入航角,后一RF航段(圆弧航段)的起始航路点、转弯方向、转弯圆心信息计算转弯方向,根据飞机当前地速以及最大横滚角计算转弯半径,通过几何关系进一步计算过渡圆心、过渡圆弧切点,从而确定过渡圆弧航迹。该方法提供了向RF/AF航段过渡的平滑飞行算法,增加了航迹的可确定性和可重复性,同时提高了载机进入圆弧航线时的飞行品质。
