The pilot's inputs are the thumb switches, and they override MCAS.

Additionally, the stab trim cutoff switch overrode both MCAS and the thumb switches.

Using both easily and successfully averts MCAS crashes, as proven in the first incident (there were three, but only two are reported on).



There were also a lot of MCAS near misses.


I only heard of one. I'm interested in others, if you have references.

I just remember that it happened commonly enough to US pilots. American pilots always recovered quickly enough that it didn't make the news before the fatal crashes.


Thank you, but it's behind a paywall. I did find this:

https://www.nytimes.com/2019/09/18/magazine/boeing-737-max-c...

which has detailed information, but I don't trust the NYT. The article also erroneously reports that the MCAS trim rate is twice the speed of manual trim. The trim rate for both is 0.27 degrees per second.
