Loss of aircraft control has hit the NTSBs Top Ten list of problems in aviation. You've got the Buffalo NY accident, the Air France accident and the Kirksville Mo accident where the pilots stalled the aircraft and didn't recover correctly. Granted these are airline accidents but I'm willing to bet these pilots had problems with stalls throughout their training.
I'm starting to see issues with stall recovery on check rides. It's not just at the private pilot level. I've had a couple of initial CFI check rides where the applicants performed poorly. One of the initial CFI applicants entered an incipient spin because he did not use the correct recovery technique.
So a question I get asked is....Chris, What do you want to see? Well, It's not what I want, it's what the FAA wants. (Typical FAA/DPE answer). The answer lies here.....
That's right from the FAA's Airplane Flying Handbook. It's a boring read but it's good information. Other manuals from Jeppesen and Rod Machado are excellent sources too.
