Very interesting. I see some countries (e.g., Sweden) have adopted the new naming conventions.
But if the FAA isn't going to follow suit then this change is worthless. Instead of unifying the nomenclature we now have three naming standards through 2022:
1. US: RNAV (GPS) and RNAV (RNP)
2. Old ICAO: RNAV (GNSS) and RNAV (RNP)
3. New ICAO: RNP and RNP (AR)
Then after 2022 the best case scenario is that we'll be back to having FAA vs. ICAO, just like before.
