Richard, I went to Kingston College and Studied the National Diploma in Aerospace Engineering course. I must say it was absolutely brilliant.
My 2004 course was the first Kingston College had started.
It is a really good course and will give you sound knowledge in alot of the technical subjects which you would need to study for the ATPL's. Very good facilities, jet engines, wind tunnel and a Lear Jet aircraft courtusy of Kingston Uni.
If you need any information, drop me a message. I would advise anyone going down the pilot training route to take this course instead of A levels. You will be more than prepared for the ATPL technical subjects.
Go for it, it'll be your best decision. It was for me, and I now have my funding sorted for the modular route which I start in October.
