An aircraft flight control system advantageously is provided with a control rod which is spline-connected to a bearing assembly so as to permit simultaneous independent longitudinal and rotational movements of the control rod while isolating such movements from one another (e.g., so as to allow operative interconnection to an aircraft's aileron and elevator control surfaces). Thus, the control rod is moveable in longitudinal and rotational directions relative to a longitudinal axis of the control rod in response to pitch and roll command inputs, respectively. The rotatable bearing assembly is adapted for connection to aileron control surfaces of the aircraft. The control rod is splined operatively to the bearing assembly so as to allow for independent simultaneous longitudinal and rotational movements of the control rod relative to the longitudinal axis thereof. As such, longitudinal movements of the control rod are isolated from the bearing member but rotational movements of the control rod are transferred to the bearing member to cause rotation thereof and thereby allow operation of the aileron control surfaces. Longitudinal movements of the control rod may however be transferred to a torque tube assembly via an articulated linkage to allow for operation of an aircraft's elevator control surface.
