JoeBob, Bear with me, I am not a commercial pilot , I have friends that are and we have been discussing this situation.There is a runaway trim cutout switch,
actually two next to each other, right by the engine start levers on the center console. The trim setting stays where it is. Then it's a matter of manually setting
w/ the big trim wheel in both sides of the pedestal. Not particularly difficult to move. If I have not explain this properly please chime in with the appropriate answer,
Thanks,Tom
As result of the combination of trim already set at the extreme/excessive angle due to MCAS and airspeed of the Ethiopian 737,
the manual [cable drive] trim wheels can be rather difficult to effectively operate.
Simply being a higher experienced pilot does not change or overcome the laws of physics.
