2 quick points -
1. Yes, apply and get the RN to decide for you, shouldn't be a problem as described by other posters.
2. Apply quick - it's quite a lengthy process and you are approaching the cut-off age. I understand that, although the RN website states the max age for Aircrew Officer as being 26, it has been reduced to nearer 24...
Good luck
Oh, and as a bonus, you'll enjoy joining the RN more than the joining the Crabs
