Make sure you get an eye test (with anyone doesnt really matter) and send it off to cranwell. I was starting to prepare for my P2 when i got my eye test back to say they wouldnt accept me as pilot because my eyes were not perfect.
Ok not a great result but im glad i found out earlier then later after i had done all my research and revision about the raf etc. Saves you alot of time if you know before hand.
