目前中国民航已成为全球第二大民航主体,预计到2025年,中国民航的运输周转量将有可能达到现在的4倍以上,运输飞机将超过5000架,运输机场超过300个。而现有的空域资源、机场容量及导航技术手段已经不能适应航空运输业的增长需求,并且世界各国都把使用新技术作为应对未来发展的重要手段。美国在2 0 0 4年推出了NextGen项目,欧洲则提出了SESAR计划。在国际民航组织(ICAO)的协调下,航行新技术在世界各国都在逐步开展之中。“基于性能的导航”(PBN)是一种重
At present, CAAC has become the second largest civil aviation body in the world. It is estimated that by 2025, CAAC’s transport turnover will likely be more than 4 times that of the current level, more than 5,000 transport aircraft and over 300 airports. However, the existing airspace resources, airport capacity and navigation technology have not been able to meet the growth needs of the air transport industry. And all countries in the world regard the use of new technologies as an important means to cope with future development. The United States launched the NextGen project in 2004, while Europe proposed the SESAR program. Under the coordination of the International Civil Aviation Organization (ICAO), new navigation technologies are gradually being implemented in all countries in the world. “Performance Based Navigation ” (PBN) is a heavyweight
