RNP AR

Same in the UK… All those brandnew IAPs such as Lands End, Barra and Islay are still titled “RNAV”….

Why is that fortunate?

Because we have been using the terminology and it has changed for no good reason and we have more RNAV (GPS) approaches (14,000+ procedures on 6400+ charts) than the entire rest of the world put together. It only serves to confuse the issue. We already changed GPS to RNAV (GPS). The US non concurred with the name change for its procedures.

Actually, RNAV and RNP are not exactly the same. From the proverbial horse ’s mouth:

Required Navigation Performance (RNP) is similar to Area Navigation (RNAV); but, RNP requires on-board navigation performance monitoring and alerting capability to ensure that the aircraft stays within a specific containment area.

I suppose the US will never use an area navigation system based on anything other then GPS, then. Europe will want to use Galileo.

Europe will use whatever is available.

There was much talk in past years of forcing Galileo for LPV, and selling decryption keys to operators.

How times change…..

Precisely.

The renaming is to be done by the December of 2022 IIRC, plenty of time. Until then, even new procedures don’t have to use it. And wasn’t it FAA’s choice to use (continue using) RNAV(GPS) instead of RNAV(GNSS)? RNAV(GNSS) has been around for quite some time, right?

The difference is moot for approaches AFAIK. RNAV(GNSS) approaches require that monitoring and alerting capability as well which means they’re all RNP.

RNAV(GNSS) approaches require that monitoring and alerting facility

How is this implemented?
