Hi, there is a loop hole you can exploit, The RAF sponsor the City and Guilds route at a discount, Hence they have blocked that for AIP as you will know, However if you apply direct to C+G and apply for a Licienetateship using 2 Years knowledge signed off by your boss together with a NVQ level 3 or BTEC as per the paperwork you can get it at a cost of about £106. Now comes the clever bit, I spoke to the WO trade sponsor who confirmed to me that "as long as you can prove that you did not use the RAF route to a Licenatateship it is ok for AIP" I know it works as I have used it, and have the pay rise to prove it. I hope this helps.
