Herein disclosed is a flight control system comprising a control member, a control surface controllable to assume different angle positions within a control angle range, a transmission linkage provided between the control member and the control surface to transmit the control force from the control member to the control surface, and a power assist actuator associated with the control member and the transmission linkage to control the control surface. The flight control system further comprises a force sensor provided between a pivot portion of the control member and a support portion of the aircraft to detect a reaction force exerted thereon by the control member and the transmission linkage, and assist force regulating means for regulating the assist force from the power assist actuator to be proportional to the control force from the control member in response to the output signal of the force sensor, thereby making it possible to give an operational feeling corresponding to the detected reaction force to the pilot without providing an artificial feeling apparatus in spite of the fact that the control surface is controlled by the power assist actuator and the human power under the normal condition.
