Computational method of longitudinal safety separation based on flight following theory

In order to accurately compute longitudinal safety separation between airplanes, the effect factors of the separation were analyzed, the effect degrees of human factors on the separation were measured according to the reaction times of controllers and pilots, a flight following model was built according to the times, the influences of the times on the separation were quantitated, and a computational method of the separation was put forward. Simulation result indicates that in flight period, the adjacency is dangerous when the separation is less than 3.0 km, whenas, the minimum computation separation is 3.6 km for flight safety, so the model and method are feasible, and are important theories to constitute flight separation standards.
