For CVs there may be a preferred format with the RAF. Maybe ask a couple of officers if that is the case.
It also helps if you CV is given with an accompanying letter, even if not asked for. The letter lets you put down in words (slow time) some of the other reasons why you should be considered. It also shows that you are a person who has gone the extra mile to make the right impression. The exception to this is if they specifically say, 'No covering letter'.
When you do a CV tailor it to the role you are applying for. Emphasize areas of expertise they will be looking for. If you are not sure, have a look at the job advert, any published job description, and anything that might have been mentioned if you have spoken to them already. For most internal jobs the interview is the decider, but the CV fills in any gaps as well as providing a richer picture of the candidate; and the CV sometimes tips the balance between two top candidates.
