Required Navigation Performance (RNP)

3. Navigation continuity

Navigation continuity ensures the computation of navigation information all along the flight. This definition includes the GNSS services. Based on these definitions several local initiatives defined their own requirements to fly some Area Navigation (RNAV) or Required Navigation Performance (RNP) operations.

This emerging environment led the ICAO to publish the PBN manual (ICAO Doc 9613) and PANS–OPS amendment (ICAO Doc 8168) in order to standardize the PBN concept for area navigation. The PBN manual specifies the scope of each RNAV and RNP operations.
