Performance Based Navigation (PBN) is comprised of Area Navigation (RNAV) and Required Navigation Performance (RNP) and describes an aircraft's capability to navigate using performance standards. RNAV enables aircraft to fly on any desired flight path within the coverage of ground or space based navigation aids, within the limits of the capability of the self-contained systems, or a combination of both capabilities.
RNP is RNAV with the addition of onboard performance monitoring and alerting capability. A defining characteristic of RNP operations is the ability of the aircraft navigation system to monitor the navigation performance it achieves and inform the crew if the requirement is not met during an operation. The performance requirements of PBN are conveyed to the operators through navigation specifications. PBN navigation specifications include Advanced RNP (A-RNP), RNP 0.3, RNP 1, RNP 2, RNP 4, RNAV 1, RNAV 2, RNP 10(RNAV 10), as well as RNAV (GPS) and RNAV (RNP) approaches.
