Back up instruments - not inadequate training
As an electronic engineer and pilot of 50 hours, before a pacemaker intervened, I an astonished that all the blame is being put on the pilots and “lack of training”. The cause of the accident is absolutely plain. The automatic systems and glass cockpit completely failed the pilots by providing erroneous and variable indications. With a carefully designed back-up of dependable instruments such as gyros and inertial navigators, and others, pilots would not be without believable data. When the automatics fail catastrophically, as in this case, they should be cut out. The so called stall would never have been believed and subsequently would not have been turned into a real stall. The fault lies with (ALL) modern aircraft design.
