In addition to the usual modern autopilot facilities, the VC10 autopilot provides Mach-number and IAS locks, and adjustable datum for the height, Mach and IAS locks; automatic throttle control of airspeed on the approach; automatic flare-out control of the pitch channel; and yaw stabilization. The automatic throttle control is for use only at low speeds, and it can be used under manual control as well as under the autopilot. A friction coupling in the autothrottle drive to each powerplant control linkage enables the pilot to override the system manually without electrically disengaging.

The autothrottle system is a dual system, either half of which can be engaged independently of the autopilot and can be used with either autopilot. The pilot's instinctive disconnect button will, however, disengage the system in use.
The throttle system drives the four throttle levers and controls the engine thrust in accordance with the required speed dialled on a digital counter located on the throttle dual controller. The Autothrottle Dual Controller is a single panel unit mounted on the flight deck centre console. It carries the switches and controls necessary for selection and engagement of the dual throttle system (System no. 1 or No. 2)

The unit has no ID plate but is similar to ODCU0566
