1. An active trim system of a flight control system of an aircraft configured to transmit a tactile feeling to a pilot of the aircraft in response to a manoeuvre, the active trim system comprising:
a manual control member configured to operate the flight control system and transmit the tactile feeling to the pilot,
an elastic deformation device having a longitudinal axis,
a reversible actuator comprising a rod and a motor, wherein the rod is parallel to the longitudinal axis of the elastic deformation device, lineally displaceable in the of the longitudinal axis and is movable by the motor and by motion of the manual control member,
an intermediate linkage member mechanically linked to the manual control member, lineally displaceable in the direction of the longitudinal axis of the elastic deformation device by the motion of the manual control member and/or of the reversible actuator and is between the manual control member and the elastic deformation device and between the manual control member and the reversible actuator, and
a controller for the reversible actuator and configured to cause the reversible actuator to move to a predetermined zero position and provide stiffness against a displacement of the intermediate linkage member by the manual control member.
