- What are RNP and ANP in area navigation? - Aviation Stack Exchange
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
- navigation - What is the difference between RNAV and RNP? - Aviation . . .
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)
- What RNP level is required for an RNP approach if the chart does not . . .
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
- Why RNAV SIDs and STARs are RNAV 1 instead of RNP 1?
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
- The meaning of RNP - Aviation Stack Exchange
As you say in your question RNP is "Required Navigation Performance" meaning to fly a particular approach, enroute leg, arrival route, etc , your RNAV equipment must continually perform to the specification required ( for example, RNP 0 3 - position accuracy of a circle radius of 3 10ths of a NM for some instrument approaches)
- What is a SAAAR RNP AR instrument approach?
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
- rnp - Which Navigation Specifications support an RF leg? - Aviation . . .
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
- Why do the approach plates for some RNAV approaches say RNP APCH - GPS . . .
So, when an approach is labeled just 'RNP APCH' (or more commonly, just 'RNAV (GPS)' with an RNP APCH note), it means it's designed to the RNP APCH performance standard For most aircraft in the US, especially those flying to lower minimums (like LPV), GPS (specifically WAAS-enabled GPS) is the enabling technology required to meet that RNP APCH
