1983年国际民航组织成立了新航行系统(FANS)特别委员会,研究、鉴定和评估一些涉及卫星的先进技术并为将来民航导航技术提供建议。在新航行系统具体实施以前乃至实施以后的很长时间里,对基于性能的空域进行安全评估都是十分重要的,是进行空域有效管理的基础。现在,所需导航性能(RNP)的优越性已经显而易见,它的出现使飞机可以在过去不可能的条件下完成飞行。
In 1983, ICAO set up a special committee for the new flight system (FANS) to study, identify and evaluate a number of advanced technologies involving satellites and to advise on future civil aviation navigation technologies. In the long run before and even after the implementation of the new navigation system, the safety assessment of performance-based airspace is very important and the basis for the effective management of airspace. Nowadays, the superiority of the required navigation performance (RNP) is already evident, and its presence allows the aircraft to fly in conditions that were not possible in the past.
