Punter's point of view
First of all let me say that I don’t want to start a flame war. Some of what I am about to say, some of you will disagree with, some will agree.
When a pilot comes to you for additional training, for perhaps an IMC, Night rating, even just a check ride to join your club. Could some respect be shown for his/her previous instructors and the habits they have formed since learning.
Some examples. If a 400 plus hour pilot pitches up and wants to rent one of your planes, you would take him for a check ride. He may have been taught many many years ago to clean up on the runway while still rolling. (carb heat away, flaps up) This may not fit in with the way you teach and may request that when he uses your Aircraft, not to do it. If on his next landing 400 hours of muscle memory take over, would you see fit to shout at him like the twit he is, or perhaps think that this pilot has been doing it this way for so long and some-one must have shown him in the first place. There are numerous examples, carb hear on the last 50’, some say put it away, some say leave it in. Flaps deployed during the turn onto base ( I was taught to do that at Biggin 20 years ago).
I think the point I am trying to make is that by the time pilots come back for further ratings, they are pretty set in their ways and don’t need …shall we say “basic” training in “basic” handling manoeuvres. What they do need is the training to start once they are under the hood.
Sorry for butting into your forum, but I always look here for some good advice (that doesn’t conflict with what I said above…well a bit)
