Hey, I am currently doing my Part 66 B1 license with AST at Perth Airport Scotland. For me it is perfect as it's not too far from family and the course (which is a IR Approved EASA Part 66) is 2 years with 2 years experience before you can apply for your ticket or you can go on the modular course and do it bit by bit but I don't know the ins and outs of it. Very friendly lecturers most are ex forces so a good laugh and can always rely on a bit of banter. There's quite a few guys there who are ex helicopter I know 2 personally one is ex navy and the other is a ex army Remi. Hope this helps you.
