it was your quote:
1. RNAV IAPs that are not RNP AR APRCH, are nonetheless performance based, as implied in the ICAO title you state
that I'm not convinced by.
In the ICAO title I stated there are no approaches named "RNAV". All approaches are RNP.
That's not to say that RNP isn't a type of "area navigation" specification which uses performance as the basis for procedural design.
Semantics I know, but as a simpleton I need as much clarity as I can get. I certainly didn’t mean to cause offence.
