Aside from that issue, what about the rest of the argument by myself and others?
Yes, I am sure MCAS works that way.
The nose down upon autopilot engagement you referred to was an
autopilot problem, not an MCAS problem. I've had the same thing happen on the 737NG. It's not really a big deal - just disconnect the autopilot and try the other one.
The 2.5 degree nose down trim input is actually less abrupt than the stick pusher devices installed in numerous other commercial aircraft. I assume you don't have a problem with those? The FAA and EASA certainly don't.
The 737MAX is aerodynamically stable throughout its flight envelope. Just because you want to believe otherwise doesn't make it so.
Yoko out.
