When I said hardware, I meant in the broader airframe hardware, not specifically electronics hardware. The physics you mention is a result of the center-of-gravity of the airframe design. The broader point being, it became cheaper and more expedient (at least superficially) to try and fix a hardware problem with software.
(Although Boeing did also create a cringey option to incorporate already existing redundant AOA sensors only as software option, rather than as a default)
- jaywalk 4y ago> The physics you mention is a result of the center-of-gravity of the airframe design. No, it's not. The larger size and more forward placement of the engines on the MAX caused it to pitch up in certain high angle-of-attack maneuvers, so MCAS was designed to automatically trim the aircraft to make it act more like the NG.
- bumby 4y agoYes, it is. But you don't have to take my word for it. >"heavier engines that are also cantilevered further forward on the wing to provide more ground clearance. That changes the center of gravity."[1] The "pitching up" is a direct result of the change in the center of gravity and thrust vector.
