Why do we get pissed off with instructors? OK, I may be a rotary FI, but I'm also a fairly average PPL(A) - just over 300 hours f/w flying over 8 years, and I avoid flying with an instructor. So I think I'm qualified to answer on this thread (I might comment on the other one too!). I think there are several reasons...
1) Money. It costs more to fly with an instructor. Some people simply can't afford it. Others think they don't need to. Still others would, if they felt they'd actually learn anything. So why do students think they can't learn anything from instructors, and are they right?
2) British culture. Anything called "instructing" or "teaching" means students regress to being like school kids. I used to teach Welsh at evening classes. I asked people if they wanted homework. They did, so I gave it to them, emphasising that it was optional. But they all got upset and embarrassed and acted like kids if they didn't do it. Is flying the same? Do pilots not want to fly with "teacher"?
3)
Its a bloody nightmare for ppl's having to bugger about relearning how to do their instructor's perversions every flight with one its no wonder they avoid instructor flights.
You said it, absolutely. So do something about egotism in instructors; there's no place for it.
OK, will that do for starters?
