9.G,
Are you dyslexic or something? The Airbus doc is Getting to grips with RNP AR... NOT RNAV AR...fix it!
BTW, when you are reading that document, the design plates, you are speaking with one of the people responsible for that design. The Departures are a custom criteria, Naverus, Quovadis, and other, have their own custom departure criteria.
While it has been shortened from SAAAR to AR, the meaning is still the same, and just because an aircraft type is certified, doesnt mean your airline bought that package, the aircraft has MAINTAINED cert, or that the Aircrew is certified.
The aircrew must be certified with RNP AR, and maintain cert, just like the ac...including flight validations of the procedures...
Your airline also needs to have operational approval from the authorities, and will likely have RNP values increased until a minimum number of flights have been
The reason the conversation keeps drifting to Approach, is thats all that is available in the public criteria, there is no RNP AR missed, or EO.
ICAO has NOT developed a Departure criteria yet, neither has the FAA....
