Boeing went complete retard with this. Which is funny, because historically Boeing is the company known to give final authority of the plane to the pilot, in contrast to their rival Airbus which relies more on the onboard fly-by-wire system. Modern planes have hydraulics and fly-by-wire, so pilots don't get the feedback they'd get if their controls were directly connected to the airfoils. To give pilots this feedback, Boeing simulates it mechanically by exerting force on the yoke. Normally this is fine and dandy, until the critical AoA sensor malfunctions and makes the computer think the plane is in a different attitude than it actually is in.

MCAS has nothing to do with force feedback on the yoke. MCAS adjusts the trim. The 737 does not have artificial feel in any case, as far as I know. There's a direct mechanical linkage from the yoke to the control surfaces, so no artificial feel is necessary.

Modern planes come with stick shaker-pusher systems: https://www.flyingmag.com/how-it-works-stick-shaker-pusher https://www.flyingmag.com/how-it-works-stick-shaker-pusher That's what I was referring to. Also whilst the 737 does have mechanical linkages to the control surfaces, they are there primarily for redundancy so the plane is flyable in case of hydraulics/power failure. By definition any hydraulics assisted system requires artificial force feedback.

    > Modern planes come with stick shaker-pusher systems. That's what I was referring to. Hmm? You were talking about systems that mimic the yoke feel of an aircraft with manual controls. A stick shaker is an emergency warning system that would never once activate on a normal flight. It has no effect on the feel of the controls. >When did I say it has anything to do with it?
