In over 20,000 hrs of flying I have never had any training in tailplane stall. We had some MD80 aircraft that we were required to push the tail deice button before selecting landing flaps but never emphasized. We had an MD80 go to landing flaps and and it pitched over into a dive and they brought the flaps back up to control it so that must have been the tailplane stall. The MD80 was a pos airplane so thought it was because of the tiny elevator that wasn't adequate for the size of the aircraft.
Every pilot should read the post relating to this because Nobody teaches it that I know.
I gave a specific training session concerning this when the information was released around 1988-89 and on. I'm not sure if it is 87 model only or 83 too. To say nobody teaches it is not correct. I hope you were given the information around clear ice on the wings.
