用于求解飞行管理问题。在约10000m高空的某边长160km的正方形区域内，经常有若干架飞机作水平飞行。区域内每架飞机的位置和速度向量均由计算机记录其数据，以便进行飞行管理。 当一架欲进入该区域的飞机到达区域边缘时，记录其数据后，要立即计算并判断是否会与区域内的飞机发生碰撞。如果会碰撞，则应计算如何调整各架（包括新进入的）飞机飞行的方向角，以避免碰撞。-Flight management for solving the problem. In the area of a square side length of about 10000m altitude of 160km, there are often a number of aircraft for level flight. Each aircraft position and velocity vector by computer records the data in the area, for flight management. When an aircraft wishing to enter the area to reach the edge of the area, after recording its data, and determine whether to calculate immediately collide with the aircraft in the region. If you collide, you should calculate how to adjust the direction of the rack (including new entrants) aircraft flying angle to avoid a collision.
