My cut and paste did not work, sorry for the incorrect acronym.
Regardless, it is of no importance to pilots flying in the US and using the GPS terminology for the last 21 + years.

I was talking about the use of RNAV(GNSS) in approach designations. Why FAA went from GPS to RNAV(GPS) is beyond me and I don’t see what it has to do with ICAO. I also don’t see the claimed annual change of terminology. This single change is happening simply because ICAO wants to switch over to PBN which is IMHO a move in the right direction. But perhaps you prefer to be stuck in the past… like there is no hope of getting rid of imperial units (I have to laugh when reading Annex 5).
RAIM (receiver autonomous integrity monitoring) for non- WAAS receivers
WAAS (EGNOS) for more modern kit includes monitoring and alerting
Either is required for iFR GPS prmary navigation receivers, so if you have RNAV x with a GPS you also have RNP x.
Isn’t RNP just something that was invented to create regulatory work, after GPS caused the bottom to fall out of the navigation business around 1995?

Are you sure that integrity monitoring is required for RNAV 5 (B-RNAV). What I’ve read (e.g. the PPL/IR PBN manual) seem to imply that it is not.
you are right – RAIM is only required for approaches (and now, P-RNAV / RNP 1).
Not even for P-RNAV, which is RNAV 1. It’s the fundamental difference between RNAV and RNP. Some P-RNAV set-ups are DME/DME without any sort of on-board monitoring.

Well, we use GPS. always have. You use GPS and call it GPSS. ICAO is great at making new terminology. You guys talk about PBN, we do it.
