Seems like a good opportunity for a young person to get some experience, but doesn't actually get you any qualifications recognised in the aviation industry, ie, a license. Oh and nvq 2/3, not worth the paper they're printed on, in my opinion, having done them.
If you want to work with helicopters, get someone to back you through your license. The 3 offshore operators in aberdeen all have schemes running.
Better yet, get onto the farnborough college course and get into Premiair, loads of different types to work on, and your aren't stuck in aberdeen!
