Centaurus, I'm going to disagree with you for the only time in my life. I promise.
Glenb. I fully agree with all the points made in your 31 May post. I must say I have been out of the general aviation instructing game for many years and that inevitably leads to failure to keep up with current thinking when it comes to offering "advice" in response to some Pprune readers queries. We are all the product of our original training and things were different in my days. Please feel free to disagree with my comments as much as you like. Nothing as refreshing as diversity of professional opinion.
