I have been following this thread with some interest as I am a PPL student (can you still be a student at age 48?) with 22 hours and so nailing the landing is of great interest to me.
If I did the 3 degree glide slope in the pattern/circuit I'd almost certainly bust Class A airspace every time at EGTF Fairoaks in the London CTR. I am sure there are many other aerodromes like this in more populated areas and countries. Mind you, it would make my circuits a darned sight more leisurely, with the bonus that I would have time to ask the stewardess for a fill up of the old hip flask.
Cheers, Howard
