> The MCAS symptoms did not match runaway trim. It's not continuous. It stops and starts. I'll pick this one. I've heard it before. Runaway trim is uncommanded movement. It does not have to be continuous, it can stop and start. That behavior can certainly happen with a short circuit or faulty wiring. It's like the speaker connections on my home stereo - the connectors corrode over time, and the sound cuts in an out randomly. The MCAS behavior absolutely presents as runaway trim behavior. Remember I worked for 3 years on the 757 stab trim system. I know what runaway trim is. > deactivating the electrical trim system would make it all too easy to enter a regime where the pilots couldn't physically recover the plane. That's why the instructions provided to the pilots said to use the thumb switches first to restore normal trim. All three crews had managed to do just that to restore normal trim. The second instance the pilots restored it ELEVEN TIMES and it never occurred to them to then turn off the trim system. You might want to review the first incident. The MCAS system came on 2 or 3 times, and each time the crew used the thumb switches to restore normal trim. Then they turned off the trim system. The flight continued and they landed safely. They knew nothing about MCAS - they just followed the runaway stab trim procedure. > I expect this kind of self-contradictory "logic" from narcissists and sociopaths Being nasty doesn't lend credibility to your arguments.
