The automatic flight system is an integral part of the automatic and manual control system of the aircraft.
Manual override of the automatic flight controls and autothrottle is always available.
The automatic flight system consists of two flight control computers with integrated autopilots, fight directors, autothrottle and engine trim controls. The automatic flight system features fail-operational Category IIIB autoland through ground roll out and integrated windshear detection/warning.
The automatic flight system incorporates speed and flight path protective features that automatically override the selected speed and/or flight path commands to prevent overspeed or underspeed.
