That malfunction manifested as the plane pitching down consistently. No matter what the input of the stick, it'd point to the floor.
Now, if a big flashy light+warning buzzer had been sounding (like with a stall warning) then this would have never happened. But it didn't, and because the pilots were not trained for this specific feature (cause it had the same rating) They didn't know what to do.
Its nothing to do with stable. the MCAS silently pointed the plane at the floor regardless of user input.
Lion Air crew did it the day before to save the aircraft. The Ethiopian Air crew almost saved their aircraft by executing that checklist. They then turned the trim back on and for whatever reason only initially commanded nose up electric trim and then stopped, leaving the system powered.
Boeing has significant fault here, but I don’t agree that pilots were not trained to deal with a stab trim runaway (obviously). The crux is whether existing stab trim runaway training was sufficient for the MCAS equipped Max. Evidence suggests it was not.
So, you agree with me? I'm confused.
They weren't trained specifically in what to do in the event of an MCAS failure, because the thinking at Boeing was that the presentation was one of stab trim runaway, something that is already trained for. I have a lot of sympathy for this point of view when looking forward from several years' ago. It turns out to have been proven wrong in the field.
