Given that the MCAS operates in intervals and does not provide constant input, it doesn't really stand that it's similar to a stick pusher as far as maintaining constant response. It seems as though it will make an evaluation and push the nose down regardless of how much stick input there is.
If the MCAS was constantly variable, like a mechanical stick pusher, then what you're saying would make sense. IMO, as reported, it seems like an 'anti-stall device' that automatically adjusts the plane's pitch regardless of stick input. Depending on conditions, this presumably could be little to no stick input.
- salawat 8y agoThat's what is so insane about this system. It was put in to make the thing act like a 737 within a very small part of the flight envelope. It never should have kicked in in normal flight. But AoA sensors freezing is apparently common enough where this system is frequently kicking in when the plane isn't in the situation it was designed for.
