RNAV vs. RNP
What is the difference between RNAV and RNP?
Re: RNAV vs. RNP
PBN describes the required navigation performance of the operation through a set of navigation specifications that include both Area Navigation (RNAV) and Required Navigation Performance (RNP) specifications.
The RNP specification differs from the RNAV specification due to the unique requirement for on-board performance monitoring and alerting functionality. The RNP specification is most commonly used for APCH, but might also be used for (e.g.) arrival or departure if no surveillance service is available.

Re: RNAV vs. RNP
Ok, thank you.
...and what does the number, following the RNAV or RNP specification refer to then?

Re: RNAV vs. RNP
The numeric value of an RNAV or RNP specification (e.g RNAV1 or RNP1) refers to the lateral navigation accuracy in nautical miles, which is expected to be achieved 95% of the flight time by the population of aircraft operationg within the airspace, on an ATS route or on an instrument procedure.
