MentourPilot is a great channel... I subbed before the Max debacle. https://mentourpilot.com It makes sense that even with two pilots trying to manually spin the trim wheels from a full nose down configuration would be nearly impossible due to aerodynamic loading. IIRC relatively unloaded manual trim wheel movement is difficult even with both pilots extending the trim wheel folding handles and spinning them with maximum effort. I would like to know if commercial simulators accurately simulate manual trim wheel difficulty under high aerodynamic loading such as full nose down trim and high speed. I think the electric trim cutout switches should be repurposed as "automation trim cutout switches" so that pilots can continue to use the yoke trim switches under high aerodynamic forces where manual trim reversion isn't possible and electric power is still available... and pilots could still revert to trim wheels during electric power loss conditions. You wouldn't disable the brake booster in a car because cruise control went haywire. |

Those trim cutout switches were actually first put in place long ago to cutout the electric trim on the yokes for situations when they get stuck or otherwise runaway.
So really what’s needed now is a different set of MCAS disable switches.
