Nose pitches up....High AoA and High G stall...
"The lack of smooth feel was caused by the jet’s tendency to pitch up, influenced by shock waves that form over the wing at high speeds and the extra lift surface provided by the pods around the MAX’s engines, which are bigger and farther forward on the wing than on previous 737s."
Low speed stall
"The flight-test pilots had found another problem: The same lack of smooth stick forces was also occurring in certain low-speed flight conditions. To cover that issue too, engineers decided to expand the scope and power of MCAS.
Because at low speed a control surface must be deflected more to have the same effect, engineers increased the power of the system at low speed from 0.6 degrees of stabilizer nose-down deflection to 2.5 degrees each time it was activated."
So now, we are getting a clearer picture of how it went from 0.6 to 2.5 degrees. According to the article, they first attempted to fix the problems by adding vortex generators and changing the wing, that did NOT work. They chose software.
Changing the wing design? This does not sound like an aerodynamically stable aircraft to me...
