Required Navigation Performance provides a specified level of navigational accuracy for the airspace or stage of flight an aircraft is operating in. 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.
Historically, aircraft navigation specifications have been specified directly in terms of sensors (navigation beacons and/or waypoints).A navigation specification that includes an additional requirement for on-board navigation performance monitoring and alerting is referred to as a required navigation performance (RNP) specification.
Localizer performance with vertical guidance (LPV) are the highest precision GPS (SBAS enabled) aviation instrument approach procedures currently available without specialized aircrew training requirements, such as required navigation performance (RNP).
Thus, RNAV is now one of the navigation techniques of PBN; currently the only other is required navigation performance (RNP). RNP systems add on-board performance monitoring and alerting to the navigation capabilities of RNAV. As a result of decisions made in the industry in the 1990s, most modern systems are RNP.
Performance standards for certain airspace are conveyed to pilots through navigation specifications published by the FAA that identify the aircraft avionics and choice of ground- or satellite-based navigation aids that may be used to meet performance requirements. PBN comprises area navigation (RNAV) and required navigation performance (RNP ...
Consistent lack of sleep not only disrupts cognitive function, but also impairs physical performance and can even contribute to hypertension, obesity, increased risk of diabetes, anxiety and ...
Since 2006, the N-RAIM Prediction Service, hosted by NAVBLUE, offers worldwide coverage for all PBN applications including RNP 10, RNAV 5, RNAV 2, RNAV 1, RNP 4, RNP 1, RNP Approach and RNP AR Approach down to 0.1NM. The online tool is an alternative to the automated service integrated directly into flight planning software.
