The invention provides an anti-collision early warning method for airplanes, which belongs to the field of flight management system design and comprises the following steps: acquiring waypoint plane latitude and longitude information of two airplanes; converting the longitude and latitude information to a spherical coordinate system, and calculating the longitude and latitude information of the cross point through a three-point coplanar simultaneous equation; and calculating an arrival distance and a time factor in combination with aircraft position information and latitude and longitude information of an intersection point, and giving out alarm judgment in combination with a time threshold value.
本发明提供了一种飞机防碰撞预警方法,属于飞行管理系统设计领域,包括:获取两架飞机航路点平面经纬度信息;将经纬度信息转换到球面坐标系下通过三点共面联立方程,解算出交叉点经纬信息;结合飞机位置信息,结合交叉点经纬度信息,计算到达距离,时间因素,并结合时间门限值,给出告警判断。
