Fodplod,
A long time ago, in a galaxy far far before the "sandy wars", RAF air and ground crews often attended the same courses you listed; ie when we had time and were not focused on one campaign. I dare say we will do so again post Herrick.
As a RW pilot I have 'dunked' more times than I can remember.....
The ability of the RN to 'mystify' maritime Avn from large decks always makes me chuckle. The art is not in the flying to/from or operating from the deck, it is the specialisation behind the planning and co-ordination of the DOTAH and FlyPro that absolutely need specialist support. Operating as an independant ships flight from a small DD/FF deck, on the other hand, is a completely different kettle of fish(heads).
