I'll also point this out "Unlike the EFS system, MCAS can make huge nose down trim changes."
That's a potential reason why an unaware pilot wouldn't disengage the auto trim system. Because he wouldn't think the trim system as being capable of causing an extreme pitch down.
Also this response.
> Interesting. So how did Boeing get a plane without redundancy in a critical sub system approved?
Answered own question, by hiding it in what is normally a non-critical subsystem.
