The invention relates to a large passenger plane horizontal interception transition path construction method based on a course variation minimum strategy, and belongs to the technical field of aviation. Acquiring aircraft data, and calculating a first distance from an aircraft initial position to a planned leg, a minimum turning radius when the aircraft flies in an arc, and a first difference value between an aircraft initial course and a flight path azimuth angle of the planned leg according to the aircraft data; judging whether the initial course extension line of the airplane is intersected with the planned leg according to the airplane data and the calculated value; determining to adopt an S-shaped speculative flight path mode, a semicircular reverse cut-in mode, a reverse flight path mode, a linear flight path cut-in mode, a baseline turning mode or a U-shaped speculative flight path mode to construct a horizontal interception transition path according to whether the horizontal interception transition path is intersected or not and the direction of the flight direction of the aircraft. According to the method, the horizontal transition path construction in the scene that the aircraft deviates from the planned leg can be realized, so that the aircraft smoothly intercepts the planned leg.
本发明涉及一种基于航向变化量最小策略的大型客机水平截获过渡路径构建方法,属于航空技术领域。获取飞机数据,根据飞机数据计算飞机初始位置到计划航段的第一距离、飞机做圆弧飞行时的最小转弯半径、飞机初始航向与计划航段的航迹方位角的第一差值;根据飞机数据和计算的值判断飞机初始航向延长线与计划航段是否相交;根据是否相交以及飞机飞行方向的指向来确定采用S型推测航迹模式、半圆弧反向切入模式、反向航线模式、直线航线切入模式、基线转弯模式或者U型推测航迹模式构建水平截获过渡路径。本发明方法能够实现飞机偏离计划航段场景下的水平过渡路径构建,使得飞机平滑地截获计划航段。
