RAF_techie101; If you are really 107 kg (~16.4 stones) then you will be (wef Dec 06) too heavy to fly on either version of the vomit comet by approx 9 kg. This is due to the MoD trying to avoid litigation in the event of an accident by imposing seat loading limitations. OASC are therefore unlikely to recruit NCA who exceed 15.5 stone and who would be limited to which branch and aircraft type they could be streamed after the first 24 weeks common phase of NCA training. This is also causing some grief for the Sqn porkers who will find themselves grounded if they dont loose the weight.
Probably not what you wanted to hear although a 9 kg weight loss is achievable, and your PTIs should be able to help you.
