偏离规范的要求授权的所需导航性能飞行程序设计及实例分析

Design and Case Analysis of Required Navigation Performance Authorization Required Flight Procedure for Deviated from Specifications

要求授权的所需导航性能(RNP AR:Required Navigation Performance Authorization Required)飞行程序设计灵活,用于高原山区和地形复杂机场可以降低运行标准.在实际运行中为降低运行标准设计的RNP AR飞行程序可能会偏离相关规范,本文研究了实际中由于地形等原因,在最后进近对正跑道的最短距离和复飞RNP值小于1的最大长度等方面偏离相关规范的情况.以国内某机场RNP AR进近程序设计为例,设计了在最后进近滚出点到入口的距离和复飞最大长度都偏离国际民航组织(ICAO:International Civil Aviation Organization)规范的RNP AR进近飞行程序,给出了进近和复飞设计参数.通过某机型的模拟机验证说明设计的偏离规范RNP AR飞行程序是可行的,能够满足运行和安全水平要求.

Because of the flexibility of RNP AR（Required Navigation Performance Authorization Required） flight procedure design, the operation minima can be reduced at airports located on Plateau or complex terrain. However, the design of RNP AR flight procedures may be deviated from the relevant specifications. In this paper, the scenarios of such deviations have been researched, for example, the shortest distance from threshold in final approach and the maximum length of a missed approach when RNP value is less than1. Meanwhile, taking a domestic airport RNP AR approach procedure design for example, a RNP AR approach flight procedure deviated from ICAO（International Civil Aviation Organization） specifications has been designed, and the final approach and missed approach design parameters have been given simultaneously. Finally, the feasibility of RNP AR flight procedure deviated from specifications which can meet the operation and safety requirement has been verified by simulator.
