Its been a long time but the transition problems remain the same. Be prepared to take a few steps back down the ladder and also go back to basics to study (cilvilians don't gen-up) for the licence exams. Civil and military aeroplane technology are pretty much the same but the terms used are often different. For example 'servicing' means topping up the oil or doing refuelling in civvy street. You can convert from military to civil quite quickly and once you have the proper licences those years of experience kick back in again and then there's no limit. There's plenty of ex-military men in hiring positions in civil aviation who know what you might be worth, but be prepared to convince them that you're ready and willing to take all the initial hard knocks that go with crossing over.
A word of advice on resettlement courses. The best ones (if they're still available) are the practical ones that teach how to do a bit of bricklaying, plastering and plumbing. Very useful for the old DIY around the house. Stay away from anything to do with management or CV writing...
Good Luck.
