Hmmmm .... isn't the colloquial name for a "restricted ATP" which allows private work but not acting as a captain on multi-crew PT flights a "CPL"? You don't need an ATP/ATPL for private flights
I fly as a Captain on a multi crew jet and hold the licenses and current type rating to do so it just happens to be FAA Hence the suggestion of a restricted ATP so that any conversion is not seen as a back door EASA ATP. there would have to be a certain amount of Grandfathering rights in achieving this but it would be easy for EASA to do
