Flight Controls (ATA 27)
Direct Cable Control Systems In the direct cable control system, the cockpit controls are connected to the control surfaces with high-strength steel cable. Operation of the control column places tension on the cable. As the cable passes through the fuselage, it is supported by the pulleys. The pulleys also enable the direction of the control cable to be changed. Tension of the control cable system is critical. This kind of control is only usable in low speed general aviation aeroplanes. The force the pilot feels on the steering column while steering the plane, is in direct relation to the airspeed. Therefore: The higher the airspeed, the greather the force on the steering column.
