my instructor would chop the throttle on me if he thought I was flying wide circuits and make me prove whether I could hit tarmac
I was flying some very tight 500 foot circuits a week ago with about 10-15 knots down the runway. If I chopped the throttle on downwind it was instructive how much height I lost in the turn (supplementary lesson -- no turnbacks for me, I hope) and just how tight the circuit had to be to make it in if the engine failed.
