随着改革开放的进一步深入,我国的民航运输事业也步入了发展的快车道,航空运输总周转量、飞行架次等各项运行指标年均以两位数的幅度攀升。近年来,为了应对和适应日益增长的空中交通流量,提升空管保障水平,部分管制中心开始实施雷达管制,在缩小了安全间隔的同时增强了安全余度, With the further deepening of reform and opening up, China’s civil aviation transportation business has also entered a fast lane of development. Operating indicators such as total air transport volume and flight sorties climbed by double-digit annual average rates. In recent years, in response to and adapting to the growing air traffic flow and enhancing the level of air traffic control, some control centers have begun to implement radar control, which has enhanced the safety margin while reducing the safety intervals.
