RNP APCH navigation specification is intended to satisfy general RNP operational requirements and permit participation by aircraft with a basic level of RNP capability without a requirement for operational authorization.

Required navigation performance (RNP) is a type of performance-based navigation (PBN) that allows an aircraft to fly a specific path between two 3D-defined points in space. Area navigation (RNAV) and RNP systems are fundamentally similar. The key difference between them is the requirement for on-board performance monitoring and alerting.

The International Civil Aviation Organization’s (ICAO) PBN Manual identifies seven navigation specifications under the RNP family: RNP4, RNP2, RNP1, Advanced RNP, RNP APCH, RNP AR APCH and RNP 0.3. RNP 4 is for oceanic and remote continental navigation applications.

rnav和rnp系统旨在通过可重复和可预测的航径定义，达到适合于应用要求的特定精度水平。 rnav 和 rnp 系统通常将来自传感器的信息，如大气数据、惯性参考、雷达导航和卫星导航，以及内部数据库的输入 数据和机组人员键入的数据进行综合处理，以实施下列功能：

This manual is intended for use by aircraft operators and procedure designers of instrument approaches based on RNP using RNAV avionics systems, where authorization is required (AR). The manual includes design criteria to aid States in the implementation of RNP AR approach procedures in accordance with the PBN Manual, Volume II, Part C, Chapter ...

2018年在局方大力推进下，陆续有机场开始制作并公布rnp ar的公共程序，中国机场的rnp ar进近图才开始出现在aip中。 今天我们就以大连机场为例，讲解一下RNP AR进近图。

2021年10月31日 · 摘要： 在我国众多的地形复杂机场，按照国际设计规范难以制定合理、高效的飞行程序，基于需要授权的所需导航性能（RNP AR）技术理念，我国经过安全评估，偏离相关设计规范实现了22个机场的RNP AR运行。 RNP AR理念在程序设计方面实际上给了中国建立自己程序设计规范的可能性。 对各机场RNP AR飞行程序偏离ICAO设计规范DOC9905的项目，以及相应的飞机机型、构型的安全评估结果和运行实际情况进行整理，在公共RNP AR理念基础上推进 …

• The new ICAO Circular 336 provides guidance to assist States and other stakeholders with the transition from RNAV to RNP approach chart identification. This circular provides the necessary guidance to States on how to make that transition.

The RNP specification for operations with authorization required (RNP AR operations) is the ICAO standard for instrument approach and departure procedures at airports with limiting terrain and obstacle environments, or other operational challenges.

2017年7月13日 · The ICAO plan, laid out in Circular 336 and Doc 8697, is to retitle RNAV approach charts to RNP. In this case using the colloquial definition—required navigational performance. Every RNAV variant currently employed would change to simply RNP except for authorization-required (AR) procedures.
