Along with what they were saying about it being more than what the pilots themselves could command as trim input If I understand the article correctly, it's interesting that the MCAS maximum of 2.5 degrees correction was reset and applied again, each time the pilots disable the system, and it auto-restarted. IIRC the article said this cycle happened 21 times over the course of those final minutes. I wonder how this looks from the pilot's perspective, compared to a trim runaway? The trim wheel isn't just spinning continuously... a good part of the time, the wheel would be stopped, it would seem. Ratcheting up in small increments, over and over, and as you mention, with a cumulative input value greater than could be manually commanded. this is what i said when i linked previously, how would a pilot cop with this when the system keep restarting ? that is the same as removing control. can the pilot turn this mcas off in flight ? i already told you! and i mentioned in in the lionair thread as well! i even posted a video of how to do it in this thread! flip the switches by the trim wheel into the cutout positions. or if you don't know how to flip switches.. you HOLD THE TRIM WHEEL STILL. WITH YOUR HAND! THAT'S IT! AIRPLANE WILL NOT CRASH. the system does not restart. it's on a timer that waits around 2 or 3 seconds from the last input, then does its thing automatically. every time there's an input from the crew, it waits then starts up. if the cutout switches are turned off, it does nothing. if you hold the trim wheel still, or crank it back to where you want it by force, it can't override you.
