前言伴随民用航空业的高速发展,航班流量的持续增长,航空管制在得到发展机遇的同时也面临更多挑战。除了空域资源稀缺、管制手段相对简单等不利条件外,越来越多的相似航班呼号给管制工作带来的不便,甚至对飞行安全的影响愈发显现。这一现象在一些空域结构复杂、日均航班繁忙区域更为突出。 Preface With the rapid development of the civil aviation industry and the continuous growth of air traffic flow, air traffic control faces more challenges as well as opportunities for development. In addition to the unfavorable conditions such as the scarcity of airspace and relatively simple means of control, more and more similar inconvenience caused by call letters to the control work and even the impact on flight safety have become increasingly apparent. This phenomenon is more complicated in some airspace structures and more prominent areas with heavy daily flights.
