Really?
TTW,
I think I flew with that instructor once; only once. No demo, shouts lots, doesn't change their delivery if you don't get it. It won't help you, and it doesn't give the school or other excellent instructors a good name. Lots of good advice already posted by others that I won't repeat.
Food for though - when I started to fly I learnt with an instructor who (without fail) calmly talked through a demonstration in the air to reinforce what he'd said on the ground. He did this with everything before getting me to do it. For a lot of the initial flying skills (turns, climbs, climbing turns, steep turns etc.) I found it infuriating as I already had a good handle on flying, but from there on in (stall recovery, spin recovery, unusual attitude recovery) I'd got so use to his mannerisms I could (nearly) always repeat his clam demonstration and patter without fail. Who you learn from and how you learn WILL set the bar you start flying from. No one enjoys flying with Captain Shouty McNoPatience.
