The comments here about good instructors and bad instructors back in the day are quite interesting. I retired at 62 three years ago to pursue a new career flying. Much of my adult life has been spent teaching, including teaching people to teach in an industrial environment.
In just over 3 years I have sent 34 people to various practical tests with all but one passing on the first go. Six of these have been initial FAA instructors. But only one of the 34 has been a traditional single engine private pilot. Even he was different - he had soloed 30 years before and had been a US Marine Corps helicopter crew chief and had grown up around family airplanes.
"Fear, Intimidation, Sarcasm, and Ridicule" I had heard before from a former USAF/retired Delta guy in my glider club. But had forgotten the specifics. I like the Peter Drucker quote.
I try to share practical tips on being a good, effective instructor with my candidates. I want them to succeed. I need to incorporate some of these stories!
A civilian trainee has a choice. A good instructor delivers good value for the money. Or the customer goes elsewhere.
Thanks for sharing, Gents!
