text: The Maneuvering Characteristics Augmentation System (MCAS), found, in two slightly-different variants, on the 737 MAX and KC-46, provides nose-down pitch inputs in certain very-high-angle-of-attack flight regimes to help make it easier to keep the aircraft from stalling;1 unlike ye olde stickpusher, another system used by many aircraft to prevent stalls,2 the MCAS provides these pitch inputs by moving the aircraft's horizontal stabiliser (something otherwise only done to trim the aircraft, which involves stabiliser movements of far lesser magnitude and rapidity than those produced by an MCAS activation), rather than the elevators (those things used for pitch control under essentially all circumstances that do not render them [the elevators] nonfunctional).
