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.

Localiser Performance with Vertical Guidance (LPV) is a subset of Area Navigation (RNAV) Approach minima that are available at some locations in various parts of the world. Approaches to LPV minima have characteristics which are very similar …

The PBN IR requires the publication of localiser performance with vertical guidance (LPV) minima, without an explicit reference to category I (CAT I) minima. The publication of 3D approach procedures based on SBAS may not enable precision approach operations down to CAT I …

LPV provides safer and more stable performance down to 200 feet decision height, regardless of low-visibility conditions. PBN is flexible, eliminating the constraints of ground-based, sensor-specific routes and procedures.

可以看出，PBN其实就是由RNAV和RNP两种导航规范构成的，越靠近机场，要求的导航精度越高。 并且只有RNP规范可以用去进近阶段！ RNAV进近和RNP进近到底有什么区别？ 我的答案是：从上图我们可以看出，RNAV是不能用于进近的，而是用于航路和进离场。

2022年1月25日 · PBN: area navigation based on performance requirements for aircraft operating along an ATS route, on an instrument approach procedure or in a designated airspace. This means four things are needed to actually utilise PBN: The aircraft needs to be PBN approved – [965/2012: CAT.IDE.A.345 (for NCO, NCC, SPO similar rules)]

这年11月，我国在三亚飞行情报区实施了RNP10的洋区PBN航路，建设了4条越洋RNP航路，提高了南中国海北部空域的空中航班流量及飞行安全性，提高了航班运行的灵活性，航班延误现象大幅减少，便捷了途经该空域的相关国际航线城市的空中交通联系。 2015年2月， 京广RNP2平行航路 完成部署，对缓解原有京广航路航班飞行拥挤问题起到重要作用。 2005年10月，美国联邦航空局 (Federal Aviation Administration， FAA）对佛罗里达空域RNAV航路实施优化，重新划设在先 …

The Performance-Based Navigation (PBN) concept describes the standards and performance requirements for navigation equipment along an ATS route, instrument procedure, or in a defined airspace. These standards determine the basis for designing flight plan trajectories and the aircraft’s capabilities

Know where to find details of the Navigation Specifications. Appreciate how the different Nav Specs relate to phases of flight. Explain the aim of Advanced RNP (A-RNP). State which Nav Specs support the Approach phase of flight. Explain how, within PBN, vertical guidance can be provided for approach operations.

RNP APCH to LNAV/VNAV minima is a vertically guided approach that can be flown with VNAV functionality using barometric inputs. Most Commercial Air Transport and Business Aviation aircraft have this capability.
