I do hope that the training department and bombardier can both prove THEY TOLD THE PILOTS THAT THE Q400 was not likely to get TAILPLANE STALL.
I don't know what info the airline training department passed on to the pilots, but the Bombardier systems description info should quite clearly describe that the aircraft has a powered irreversible flight control system for the elevator. Thus the crew should have been aware that changes in air loads on the elevator could not cause the controls to suddenly move forward. If the airline simply showed the NASA training material with the Twin Otter tail plane stall video, without explaining the important ways the -400 differed from the Twin Otter, then they did a shoddy job, in my opinion.
