If everyone in GAAP did nice tight circuits not wide B747 circuits this would not even rate a mention the runway would be in glide distance from mid downwind as it should be.
i have been roasted a few time by CFI's for teaching, try to make every approach a glide approach. once the power is back to slow down on mid downwind, the throttle shouldn't be touched again until you need it to taxi. unless of course the student is going for CPL and higher.. then ill teach the 3 deg approach.
its how i was taught all those yrs ago, and its saved my arse once. and i teach it to my students. fortunately the CFI now approves of my technique.
