在被飞行员用于描述偏置航路时，除了在雷达控制的情况下，确定直线航段的导航点成为必报点。

但在景象匹配过程中会不可避免的会出现匹配错误、匹配精度不够等问题，为此，基于景象匹配过程中载体机动性能规律，提出了飞行航迹近似为直线的误匹配点剔除方法。
Based on the carrier maneuverability law in scene matching process, the paper presented a method for eliminating the mismatching points when the flight track was approximated to a straight line.
预定的飞行轨迹可以有两种规划方式，一是近似在当地切平面上的直线或曲线；
One is straight line or curve on the local plane. The other is the great circle flight path on the earth surface.
