In ACN 1597380 - why would MCAS kick in if he wasn't manually flying (pilot states autopilot was engaged specifically to avoid MCAS)?
I'm wildly speculating here, but since wing loading is also a factor in calculating the angle of attack at which a potential stall condition could occur, I'm also wondering if it relies on the accuracy of the weight and balance the pilots enter into the flight computer. Pilots have missentered such critical information before.
