Not at all spinex, I am the first to admit that we all, as humans, are fallible - me no doubt more than most
There appeared to be a developing consensus though of a certain amount of blame being laid at the door of the instructing sector in general. I thought it would be unfair that the local Flying school become tarred with the brush that was provided by the select few (who appear in any sector of our industry) who use incorrect technique or otherwise lower the standards of our great profession.
I think the term 'pulling the throttle back' is accurate on descent. Pulling it all the way back? Not too clever of course.
I suspect that almost all instructors out there (I'm desperately hoping) understand the risks of excessively low power settings coupled with rich mixtures and cool temps. It is preached ad nauseum in all the text books and exams...
Anyway, as I said - perhaps poor technique initiated the problem, but decent training contributed to a good outcome in the end.
