Crap,
Things ain't what they were mate. I did the "old" Army Pilot course 20 years ago, did my 4 years bond afterwards (total time served, 15 years), then did my ATPL(H) exam crammer at the City of London Poly as a resettlement course. Very cheap !!
If you plan to join and do an Army course, if you have the qualifications my advice would be to go the officer route as you'll go straight on a course after Sandhurst.
Hope this is of some help.
Cheers,
NEO
