It now looks like manual trim is nearly impossible at higher speeds.
It puzzels me a bit that the stab can be trimmed so far it will bring the aircraft out of the pilot’s control. And then you can’t manually bring it back under control because the trim forces are too high.
How Boeing will solve this is beyond me. MCAS is a killer and if they restrict it it will affect the certification. In order to get rid of MCAS they have to redesign the aircraft.
IMHO the MAX will stay on ground for a long time.
Yes but that's a function of aerodynamic load.
My point was that anyone can turn a wheel regardless of hours (obviously if it's not prevented by aerodynamic load) so to suggest that the FO couldn't turn it because he had only 200 hours was and is total nonsense (and I know you didn't make that point).
