This fact sheet will focus on the most common navigation specification called “RNP Approach (RNP APCH)” and titled Area Navigation (RNAV), “RNAV (GPS) Rwy XX”. These procedures offer several lines of minima to accommodate varying levels of aircraft equipage and airport environments without requiring additional navigation equipment at the airport.

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. Area navigation (RNAV) and RNP systems are fundamentally similar. The key difference between them is the requirement for on-board performance monitoring and alerting.

Required Navigation Performance (RNP) is Area Navigation (RNAV) with on-board navigation monitoring and alerting; RNP is also a statement of navigation performance.

Required Navigation Performance (RNP) General. While both RNAV navigation specifications (NavSpecs) and RNP NavSpecs contain specific performance requirements, RNP is RNAV with the added requirement for onboard performance monitoring and alerting (OBPMA). RNP is also a statement of navigation performance necessary for operation within a defined ...

As a transition, until 30 November 2022, approach charts depicting procedures that meet the RNP APCH navigation specification criteria must include either the term RNP or RNAV (GNSS) in the identification (e.g. RNP RWY 23 or RNAV (GNSS) RWY 23). However, from 1 December 2022, only the term RNP will be permitted.

The International Civil Aviation Organization’s (ICAO) PBN Manual identifies seven navigation specifications under the RNP family: RNP4, RNP2, RNP1, Advanced RNP, RNP APCH, RNP AR APCH and RNP 0.3. RNP 4 is for oceanic and remote continental navigation applications.

2012年7月18日 · Some pilots remain confused about GPS-based RNAV approaches, especially procedures with RNP (Required Navigation Performance) in the title and AUTHORIZATION REQUIRED (AR) notes on the chart. For many reasons, those approaches (now called RNP AR procedures) are currently off-limits to a typical IFR pilot flying an …

2018年4月17日 · This column provides the name of the parameter to be compared, e.g., threshold crossing height, vertical angle, waypoint location. This column provides the largest cycle to cycle change in the parameter that may safely be accepted without concern when validating the procedure. The numerical tolerances are all plus or minus values.

RNP is intended to characterize an airspace through a statement of the navigation performance accuracy (RNP type) to be achieved within the airspace. The RNP type is based on a naviga-tion performance accuracy value that is expected to be achieved at least 95 percent of the time by the population of aircraft operating within the airspace.

– Implementing RNP APCH does not require new airworthiness demonstrations & documentation – Charts will continue to be labeled RNAV (GNSS) • Keys on compliance to European & US performance & functional specifications – Ensures compliance to ICAO specification – Simplifies operational implementation for States
