PBN stands for performance based navigation. It includes RNAV and RNP. PBN relies on GNSS, which can provide high navigation accuracy. Because of PBN, we can fly from one waypoint to another waypoint directly.PBN代表基于性能的导航（Performance - Based Navigation）。它包含区域导航（RNAV）和所需导航性能（RNP）。PBN 依赖全球导航卫星系统（GNSS），可提供高精度导航。借助 PBN，我们能直接从一个航路点飞往另一个航路点。

RNP stands for Required navigation performance. It is a part of PBN. It relies on GNSS, which can provide high navigation accuracy. Because of RNP, we can fly from one waypoint to another waypoint directly.RNP代表所需导航性能（Required Navigation Performance）。它是 PBN（基于性能的导航）的一部分。它依赖全球导航卫星系统（GNSS），可提供高精度导航。借助 RNP，我们能直接从一个航路点飞往另一个航路点。

RNAV stands for area navigation. It is a part of PBN. It relies on GNSS, which can provide high navigation accuracy. Because of RNAV, we can fly from one waypoint to another waypoint directly.RNAV代表区域导航（Area Navigation）。它是 PBN（基于性能的导航）的一部分。它依赖全球导航卫星系统（GNSS），可提供高精度导航。借助 RNAV，我们能够直接从一个航路点飞往另一个航路点。

Compared with the conventional navigation. It is more accurate, more reliable and more safe.

RNAV is area navigation. RNAV can only be used en - route and during arrival. As for RNP, not only it can be used en - route and during arrival, but also during final approach and go around.RNAV是区域导航，仅可用于航路阶段和进近阶段。至于 RNP，它不仅可用于航路阶段和进近阶段，还可用于最后进近和复飞阶段。
