2018年11月19日 · 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.

2018年5月4日 · 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).

2020年9月8日 · 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.

2020年8月22日 · 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.

2017年3月14日 · 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.

2016年3月18日 · RNP (Required Navigation Performance) is a standard which avionics manufacturers may choose to design/certify their products for. It guarantees a particular level of navigation performance that routes and procedures can be designed around, and not have to worry about how the navigation is being conducted, but only that it will meet requirements.

2024年10月11日 · 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.

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.

An area navigation system capable of achieving the performance requirement of an RNP specification is referred to as an RNP system. PBN (as defined by ICAO Doc 9613): Area navigation based on performance requirements for aircraft operating along an ATS route, on an instrument approach procedure or in a designated airspace.

2016年8月1日 · 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.
