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.

Area navigation (RNAV) is a method of navigation that permits aircraft operation on any desired flight path within the coverage of ground- or space-based navigation aids, or within the limits of the capability of self-contained aids, or a combination of these. The …

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.

This job Aid was developed by the Regional Cooperation System for Safety Oversight (SRVSOP) to provide guidance to States, operators and inspectors on the process for operators to obtain an RNAV 5 authorization. 2. Purposes of this Job Aid. 2.1 Provide RNAV 5 reference documents for operators and inspectors.

RNAV 5 operations are based on the use of RNAV equipment which automatically determines the aircraft position in the horizontal plane using input from one sensor or a combination of the following types of position sensors, together with the means to establish and follow a desired path:

Incorporates RNAV 5, RNAV 2, RNAV 1, RNP 1 and RNP APCH. Applicable for oceanic/remote, continental en-route, arrivals, departures and approaches. Relies solely on integrity of RNP system without recourse to conventional means of navigation. Note: Most helicopters are fitted with stand-alone receivers which operate in fixed modes.

The fifth edition from September 2003 outlines abbreviations, definitions and terms, an executive summary, and sections on RNP and RNAV concepts, RNAV applications for en route airspace including route spacing, and types of RNAV routes.

These routes and approach procedures are to be based on the RNAV 1, RNP 1, RNP 0.3, RNAV 5, RNP APCH (to LNAV, LNAV/VNAV and LPV minima) or RNP AR APCH specifications, as required by the PBN IR implementation deadlines.
