Dick,
SAAAR (Special Aircraft and Aircrew Authorisation Required) approaches are in use throughout the world, not least of which in your beloved USA. We do SAAAR approaches into JFK and LAX, as well as the seychelles.
I, and any pilot who wants to fly those approaches have to have our operation in terms of aircraft, procedures and training approved specifically for each approach.
So, if it happens in the USA, it MUST be right, right?
Just a thought-if you want to do that approach, why not meet the requirements to get the approval?
