• Normal operation : Captain and First Officer inputs are algebrically summed.
• Autopilot disconnect pushbutton is used at take-over button.
• Last pilot who depressed and holds take-over button has priority ; other pilot's inputs ignored.
• Priority annunciation : - in front of each pilot on glareshield - ECAM message - audio warning.
• Normal control restored when both buttons are released.
• Jammed sidestick : - priority automatically latched after 30 seconds - priority reset by depressing take-over button on previously jammed side stick.
