im also surprised to see that they urgently need pilots
You won't be the only one that's surprised by that!
Seriously, applications for pilot in the RAF are massively oversubscribed, by thousands in fact. Those few that make it through are the most dedicated, the most determined, and the most outstanding applicants. It's not something you can just have a crack at because you like aircraft.
Have a read through the sticky entitled "Joining the RAF / OASC" at the top of the forum page, you'll probably find that all your questions will have been answered before.
Slightly off topic: (Quoting dagowly)
