AILERON CONTROL
Lateral (roll) control is provided by ailerons operating in relation to control wheel displacement and controlled via control rods, cable runs and quadrants. The ailerons are assisted by four multi-function spoilers per wing, which are electrically controlled.

Aileron Control System
Two separate lateral control systems are provided: the pilot’s side operates the left-hand aileron and the copilot’s side operates the right-hand aileron.
Normally, both control systems are interconnected through the forward torque tube interconnect assembly and there is simultaneous movement of both ailerons.

AILERON CONTROL (CONT'D)
Aileron Control System Operation
The pilot and copilot roll controls are interconnected through a roll disconnect mechanism used to maintain the control wheels connected, until a design torque is developed across the mechanism.
A jammed aileron control circuit can be isolated through automatic activation of the roll disconnect mechanism. This procedure will allow limited lateral control using one aileron and all multi-function spoilers through the operable control circuit.
NOTE

The Automatic Flight Control System (AFCS) should be disconnected if a jammed aileron control circuit condition occurs.
A transducer is mounted at the outboard end of each torque tube assembly (forward quadrant). They provide the roll command inputs to the multi-functional spoilers system for roll assist.
Rotating either control wheel provides an input (via cables and pulleys) to the aileron forward quadrant which directs the control cable to the aft quadrant.
Each aft quadrant has an artificial feel and centering unit. An aileron trim unit is installed with input to each aft quadrant and provides trim input to the aileron control system.
A separate cable circuit is provided for the autopilot servo motor (controlled by the AFCS) assembly which inputs the right aft quadrant.
Disconnecting the autopilot by the pilot overpowering the aileron servo will not cause the auto roll disconnect system to separate the control wheels.
NOTE

Overpowering the aileron servo to disconnect the autopilot is not recommended.
The control cables from the aft quadrant continue outboard to the hydraulically driven PCUs. There are two PCUs for each aileron control surface.
