I'm with Tinstaafl (OK, where's the name from?) on this one. It's the same thing as letting learner drivers **** around at roundabouts etc. It annoys everyone but when you think about it, it has to be done. Not everyone is an ace so people have to be allowed time to catch up with it all. Flying training, at whatever stage, is all about having sufficient spare mental capacity to handle the situation so if it means flying a few wider, slower circuits then so be it. Pushing people too far at that stage will more than likely discourage them which is not the aim in flight training. Besides which, when I have a student who is finding it all too much in the circuit and I get them to widen it out a bit it always seems to help. I rest my case.
