Funny old thing it being bias towards rotary! Something to do with the large number of helo aircrew, as opposed to the very small number of Fw aircrew in the Navy! (which incidentally have been given to the air farce anyway!)
You get streamed on a mixture on your ability/aptitude and the logistics of bums on seats and spaces available. It is nothing to do with Dartmouth - the flying instructors at JEFTS decide which have the aptitude to go fixed wing - 1 or 2 per course. The ones with crew concept, good looks and team spirit get to fly rotary
Easiest way to get through the AIB is to be yourself! If you dont pass, then the job isnt for you probably. The Navy will expect more on the leadership side than our air farce collegues as when you are at the sharp end, you are quite literally all in the same boat
so no - oh I possibly couldnt do that, I am just here to fly attitude.
