The invention belongs to the technical field of flight management systems, and particularly relates to a 60-degree intercepted track calculation method. The method comprises the following steps: extracting flight plan information, calculating a turning direction according to current flight path angle and current flight segment azimuth angle information of an airplane, and further calculating an azimuth angle of a linear transition segment; calculating a starting point coordinate of the linear transition section, calculating an end point coordinate of the linear transition section, calculating a turning circle center coordinate corresponding to the transition arc 1, calculating a turning circle center coordinate corresponding to the transition arc 2, and calculating a turning end point coordinate corresponding to the transition arc 2; and finally calculating to obtain a complete track of 60-degree interception transition by combining the current position of the aircraft, the current position entry angle of the aircraft, the flight waypoint and the entry angle of the flight waypoint in the flight plan. According to the method, the certainty and repeatability of the flight path are improved, meanwhile, the aerial carrier can rapidly cut into the next flight path, and the flight time is shortened.

    本发明属于飞行管理系统的技术领域,具体涉及一种60°截获航迹计算方法。该方法通过提取飞行计划信息,根据飞机当前航迹角和当前航段方位角信息,计算转弯方向,同时进一步计算直线过渡段的方位角,首先计算过渡圆弧1对应的圆心角,计算直线过渡段起点坐标、计算直线过渡段终点坐标、计算过渡圆弧1对应的转弯圆心坐标、计算过渡圆弧2对应的转弯圆心坐标、计算过渡圆弧2对应的转弯结束点坐标,结合飞行计划中的飞机当前位置、飞机当前位置入航角、应飞航路点、应飞航路点入航角,最终计算得到60°截获过渡的完整航迹。该方法增加了航迹的可确定性和可重复性,同时可以使载机快速切入下一航迹,缩短飞行时间。
