D TURN Knob -- Rotating the turn knob out--of--detent with the
autopilot engaged generates a roll command. The roll angle is
proportional to, and in the direction of, the turn knob rotation. The
turn knob control sends identical roll commands to both flight
guidance computers. The turn knob must be in the detent (center
position) before the autopilot can be engaged. Rotating the turn
knob cancels any engaged lateral flight director mode.
D Pitch Wheel -- Rotating the pitch wheel changes the pitch attitude
proportional to, and in the direction of, the wheel movement. The
pitch wheel outputs either rate limited pitch commands in pitch
mode, or vertical reference commands for vertical flight guidance
modes (referred to as the air data command function).
