保证飞机按给定时刻到达目标点是实行空中交通管制自动化首先要解决的问题．本文通过对飞机运动微分方程的迭代求解，给出了准确保证按时到达的轨迹的一般算法，并在此基础上研究了直线航路限制和无航路限制下单转弯、双转弯、三转弯及盘旋加转弯等几种典型情况的轨迹算法及其适用条件．算法中考虑了定常风力对按时到达飞行轨迹的影响，并提出了解决方案．这些算法兼顾乘坐品质，具有简单、易于求解的特点
To ensure that the aircraft reaches the target point at a given moment is the first issue to be solved in the implementation of air traffic control automation. In this paper, the general algorithm for accurately ensuring the trajectory arriving on time is given by means of iterative solution of the differential equation of the airplane. Based on this, the author studies the single-turn, double-turn, triple-turn and circle-plus Turning and other typical trajectory algorithm and its application conditions. The algorithm takes into account the effect of steady wind on the flight path arriving on time and presents a solution. These algorithms take into account the quality of ride, with simple, easy to solve the characteristics
