RNP AR进近程序的对比分析及其安全评估

Comparative Analysis and Safety Assessment of RNP AR Approach Procedures

所需导航性能授权(RNP AR)方法是基于性能的导航程序之一,可在繁忙和具有挑战性的山区实现更安全和高效的飞行操作。在这项研究中介绍了RNP AR APCH程序的特点和优势,该程序将是防止受控飞行撞地(CFIT)事故的解决方案。由于缺乏精密进近,CFIT事故多发生在飞行的进近和着陆阶段。此外,还分析了仅针对RNP AR APCH程序发布的飞行运行安全评估(FOSA)方法。FOSA是RNP AR APCH程序运行授权的重要组成部分,也用于评估特定情况,是降低CFIT风险的有效方法。

The Required Navigation Performance Authorization Required(RNP AR)approach,which is one of the performance-based navigation procedures,enables safer and efficient flight operations in busy and challenging mountainous areas.In this study,the characteristics and advantages of the RNP AR APCH procedure are introduced,which will be a solution to prevent controlled flight into terrain(CFIT)accidents.CFIT accidents mostly occur in the approach and landing phase of flights because of the lack of precision approaches.Moreover,flight operational safety assessment(FOSA)methodology published for only RNP AR APCH procedures is assessed.The FOSA is a significant part of the operational authorization for RNP AR APCH procedures and also is applied to evaluate particular cases and could be useful method for mitigating the risk of CFIT.
