May 4, 2018 · RNP, or Required Navigation Performance adds specific performance standards onto RNAV systems. It defines several levels of performance that are applied to specific airspace and operations. The need for these levels is driven by airspace management and air traffic control (keeping planes from running into stuff or each other).

RNP is a numerical value that refers to the level of performance required for a specific published procedure. If the procedure has an RNP 10, then the on-board navigation equipment must be able to calculate its position to within 10 nautical miles. If the procedure has an RNP 0.3, than the equipment must be able to calculate its position to .3nm.

Sep 8, 2020 · In an RNP approach, you have a clearance of two times the RNP value (0.30 x 2 = 0.6 miles) and also a buffer of 0.2 miles either side. In an RNP AR approach, the buffer is taken out of the picture and it only offers two times the RNP number left or right. If the RNP value is 0.10, then the lateral obstacle clearance will be 0.20 miles either side.

Aug 22, 2020 · The SIDs and STARs can either be RNAV 1 or RNP 1. RNAV 1 is the system introduced at the start of performance based navigation to cater for smaller air spaces (terminal area procedures) and it is a step towards changing over to RNP 1. Many countries these days require an aircraft with RNP 1 capability to fly their SIDs and STARs.

Mar 14, 2017 · If an approach requires tighter limits, such as RNP 0.3 or 0.15, then special authorization is required. This is where SAAAR comes in (Special Aircraft and Aircrew Authorization Required), now renamed to RNP AR (RNP Authorization Required). RNP AR routes only make use of TF and RF leg types to fully fix the lateral path.

Oct 11, 2024 · The procedure design in different types of RNP approaches is different although they are described on the same chart. While the vertical profile for 2D approach with LNAV minima is similar to other 2D approaches such as VOR, the 3D APV Baro-VNAV does not have any stepdown fixes or MDA.

Aug 1, 2016 · Also RNP AR required equipment is specified in several sources and the FCOM manual of airbus. In addition for RNP 2 specific terminal and approach operations the requirements are specified on the approach charts of airports that implementing it. Most of the operators/airlines are using the standard required equipment for RNP 1.

PBN which is contrast to conventional navigation consists of RNAV and RNP. And I know that general RNAV approach of IAP has up to 4 minima such as LPV, LNAV, LNAV/VNAV, and LP. And I know that GLS approach is precision approach that use GBAS as well as GPS, but GLS approach procedure chart is separated with RNAV approach chart.

Jul 2, 2020 · Let us assume you are flying a B737NG and you are cleared for an RNAV (RNP) approach which has several legs with different altitude crossing restrictions. What do you enter in the MCP altitude win...

RNP is newer ICAO terminology under their Performance Based Navigation model, which essentially means they don't care how you get your navigation data, just how accurate it is. The better your Actual Navigation Performance is (i.e. lower number), the lower the approach minimums you get to use.
