As I pointed out in an earlier post the upengined -8 had a tendency to go nose up at 100% power. Which usually happens only at takeoff when the aircraft is the most vulnerable. The wings, at that time are also configured for higher lift to gain altitude so that might have an effect as well. Looking at the position of the engine it appears that some of the thrust from the turbofan portion of the engine is directed over the wing causing a dramatic increase in lift.This should have been sold as a new plane. The engines are moved forward on the wings, and they are more powerful. In a light load on this model it pushes the nose up very quickly which could lead to a stall which is why the MCAS
It appears that this specific model Max 8, had more powerful engines installed, and they were installed more to the front of the wings. This would cause the nose of the aircraft to want to rise more quickly, which could cause a stall. To counter this, the engineers at Boeing, installed the MCAS system to counter this. Boeing should have introduced this as a new plane, but to avoid the regulations, and associated costs, they sold it as the same plane with upgrades. With 56% of the total fleet currently grounded, and Boeing stock losing 8% of its value today. It will be a hard sell that both crashes are due solely to pilot error. We shall see.
