Performance-Based Navigation (PBN) and Area Navigation …
Within PBN there are two main categories of navigation methods or specifications: area navigation (RNAV) and required navigation performance (RNP). In this context, the term RNAV x means a specific navigation specification with a specified lateral accuracy value.
所需导航性能(RNP)进近和区域导航(RNAV)进近到底有什么 …
图中,RNP为1,ANP为0.21(数字越小,精度越高),满足性能要求。 所以,飞机只要监视着RNP>ANP就好了. RNAV导航的精度不是达不到最后进近阶段的要求吗? 以上就是 RNP进近(RNP APCH) 的三种方式,还有一种叫做 RNP AR (一种比RNP APCH更精密更高级,需要局方授权的神秘进近方式,目前我还没有揭开它的神秘面纱…) 这里需要提一下的是,我们知道只提供水平指引的叫做非精密进近。 提供水平+垂直指引的叫精密进近。 那类精密进近是啥玩意 …
ENR 1.17 Performance-Based Navigation
Within PBN there are two main categories of navigation methods or specifications: area navigation (RNAV) and required navigation performance (RNP). In this context, the term RNAV x means a specific navigation specification with a specified lateral accuracy value.
RNAV and GPS: What's The Difference? - Boldmethod
2024年5月18日 · Required Navigation Performance (RNP) is a form of navigation that allows an aircraft to fly directly between two 3D points in space. The fundamental difference between RNP and RNAV is that RNP requires on-board performance monitoring and alerting capability.

This in-depth comparison covers guidance types, infrastructure needs, certification requirements, and common challenges, helping pilots and aviation enthusiasts understand when and why each approach is used.
PBN、RNP与RNAV的相爱相杀 - 知乎 - 知乎专栏
RNAV>PBN>RNP. RNAV全称区域导航(Area Navigation)。其实,当人们通过VOR/VOR、VOR/DME、DME/DME等定位方式来代替最初仅仅基于导航台之间的航路时,就意味着区域导航(RNAV)已经诞生了。是的,你想的没错!其实这么多年你一直在飞RNAV,只是没有人告诉你 …
民航新技术的运用——PBN运行 - 豆丁网
2012年3月11日 · 所有rnpar运行都必须抑制vor更新。 当复飞rnp值小于0.6nm时需要抑制dme-dme更新。 在gps失去信号时,可防止fmc从vor或dme进行位置更新, 达不到程序的精度要求。 在失去gps信号没有无线电更新时,fmc依靠惯导更新。 (anp在30分钟不会超过4nm) 抑制vor更新
Required Navigation Performance (RNP) - SKYbrary Aviation Safety
Required Navigation Performance (RNP) is a family of navigation specifications under Performance Based Navigation (PBN) which permit the operation of aircraft along a precise flight path with a high level of accuracy and the ability to determine aircraft position with …
基于性能的导航进近程序与传统进近方式有何不同? - 知乎
这个导航允许误差叫RNP(Required Navigation Performance)。 如果是这个航段最大允许X海里,那么也写作RNAV X。 很显然,如果某个航段的RNP是2海里,机载设备又满足RNAV 2的标准,那么就可以飞这个航段,机载设备只满足RNAV10的就不要飞这个航段了。
非精密进近——VOR/DME进近 - 知乎 - 知乎专栏
目前我国民航系统可以提供非精密进近程序的方式有:vor进近、vor/dme进近、ndb进近、ndb/dme进近、rnav(gnss)(rnp apch)进近和rnp(ar)进近。其中rnav(gnss)(rnp apch)进近和rnp(ar)进近由于精度相比传统非精密进近高,又被称为类精密进近。
