针对民用机场净空管理过程中锥形面范围难以准确确定,主要采用手工方式绘制障碍物限制面图进行管理的问题,给出了净空管理过程中受城市建设影响较大的、形状最为复杂的锥形面范围,导出了锥形面边界的计算方法,并确定了围限锥形面的各关键点坐标,为采用计算机自动判定障碍物是否落入锥形面奠定了理论基础。 In view of the difficulty of accurately determining the range of conic area in civil airport clearance management, the problem of manually managing obstacle restriction surface map is mainly solved. The conical shape with the most complicated shape The calculation method of the conical boundary is deduced and the coordinates of the key points of the conical cone are determined. It establishes a theoretical basis for automatically judging whether the obstacle falls into the conical surface by computer.
