在雷达管制条件下,随着飞行流量的逐年增加,要求管制员对航空器的调配精度也越来越高,使得管制员对航空器航行诸元的控制也逐渐由少到多,由粗到细。这种要求的转变在区域管制室由程序管制向雷达(监控)管制的过渡过程中显得尤为明显。过去那种简单、粗糙的以阶梯上升/下降为主的 Under the condition of radar control, as the flight flow increases year by year, controllers are required to deploy aircraft with higher and higher precision. As a result, controller’s control over the elements of aircraft navigation gradually decreases from coarse to fine. The shift in this requirement is particularly evident during the transition from procedural regulation to radar (monitoring) of the regional control room. The simple, rough step up / down dominated in the past
