On the approach (B757/767) the pitch attitude (controlled by the elevators) is adjusted by the autopilot as required to follow the glideslope. At flare height (20 ft) the pitch control input switches from glideslope to radio altimeter. The autothrottle simultaneously retards the thrust levers to idle. At touchdown the localiser input is switched from the roll channel (controlled by the ailerons) to the rudder to correct potential centreline deviation. Reverse thrust is manually selected. Wheel braking is auto or manual.
