Is RNP and RNAV the same?

Area navigation (RNAV) and RNP systems are fundamentally similar. The key difference between them is the requirement for on-board performance monitoring and alerting. RNP also refers to the level of performance required for a specific procedure or a specific block of airspace.

What is an RNAV route?

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.

What is the difference between RNAV GNSS and RNAV RNP?

There have been questions on whether GNSS is an RNAV or RNP system. The answer is GNSS is both an RNAV and RNP system because RNP is a subset of RNAV that also includes a requirement to provide on-board navigation system accuracy performance monitoring and alerting. Therefore, an RNP system is also capable of RNAV.

What is an RNAV RNP approach?

Required Navigation Performance ( RNP ) is similar to Area Navigation ( RNAV ); but, RNP requires on-board navigation performance monitoring and alerting capability to ensure that the aircraft stays within a specific containment area. There are several different levels of RNP .

What is RNP approach?

Required Navigation Performance (RNP) is a family of navigation specifications under Performance Based Navigation (PBN) which permit the operation of aircraft along a precise flight path with a high level of accuracy and the ability to determine aircraft position with both accuracy and integrity.

What is RNP airspace?

RNP refers to the level of performance required for a specific procedure or a specific airspace block. An RNP of 0.3 means the aircraft navigation system must be able to calculate its position to within a circle with a radius of 3 tenths of a NM. The FMS is a key component of an RNP compliant installation.
