Nerves having clearly been touched Asturius! At least this dichotomy has been brought out into the open now.
ATG:-
no - wrong.
That is not the entire definition of Aircrew. And you know it.
I suspect you you need to stop tilting at this windmill.
Are the windmills again! Never far away. Your previous post requested guidance but it seems you need none as your mind, like others here, is clearly already made up. So I won't offer you guidance but simply repeat that RAF CC are part of a basic crew when passengers are carried. When those passengers require additional specialist attention, such as on casevac flights, then supernumerary crew (in this case probably RAF Medical Branch and PMRAFNS personnel) are added to that basic crew. You still need the core basic crew defined by the MAA as Aircrew (though not it seems by the RAF). That's what I know ATG!
