U13 is the first for the MAX http://www.b737.org.uk/mcas.htm Interesting... http://www.b737.org.uk/glareshield.htm#fcc indicates that Collins is responsible for the component that processes this sensor (Though I suspect the inputs go through the GE Aviation FMS/FMC -- which likely means only the primary FMS side is passed on). The FCC is more what might be considered a "classic" "auto-pilot" [as can be seen -- desired air speed, heading, altitude, and ascent/descent rates); the FMS handles route optimization, GPS paths, etc. along with collecting and relaying data to the display systems.. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com
