Patent ID: 8655509

Claim:
A flight control system of an aircraft, comprising: a flight control device; a sensor configured to detect a first parameter as at least one of a plurality of parameters changed based on a flight condition of the aircraft; a limitation flight control position calculating section configured to calculate a limitation flight control position of said flight control device when said first parameter reaches a limitation value, based on the detection result of said sensor; a reaction force generating command calculating section configured to generate a reaction force generating command based on a flight control position of said flight control device and said limitation flight control position; a reaction force generating actuator configured to change a reaction force which a pilot receives when carrying out a flight control input to said flight control device, in response to said reaction force generating command; an inner loop command calculating section configured to generate an inner loop command based on said flight control position; and a control surface actuator configured to drive a control surface of said aircraft in response to a control surface command obtained from said flight control position and said inner loop command.
