Read back over this forum's posts as there have been many in your situation asking the same question here. You have a wealth of experience which will see you into commercial aviation I have little doubt, the issue for you is at what level. My guess is you have an induction period into the airline world, but there is much you can do before your leave the RAF in study of our commerical regualtions and operating rules and regulations, such as JAR and EASA regs. You might also consider working in the NAV and Performance department most airlines have, few ex NAV available these days and finding those with suitable experience can be a problem. Good luck.
