The Army, weirdly enough, has a website, and that website, weirdly enough is dedicated to answering such questions. A little initiative would have saved you making a fool of yourself and answered this question, any or all of the other questions you may have had, and maybe some you didn't know you had. Fucktard.
I gather from a post on another thread you are not yet serving. And it appears you are intending to join as a soldier? This doesnt preclude you from becoming a pilot but it is a long process From where you are now I would suggest 8 years minimum. You cannot join as a pilot directly as a non officer. I gather youre a bit of a fatty too? You do actually need to be fit to be a pilot you know? Read the link provided by Fingerz and let me know if youre a spaz in anyway.
Made me chuckle to see the pic of the bloke on the AAC page. He's disabled. He's Scottish.
