1. A piloting assistance device for assisting the piloting of a rotorcraft, the rotorcraft being provided with a flight control for controlling a rotor via at least one linkage provided with a plurality of rods including at least intermediate rod and link means, wherein the device comprises:
- an instantaneous force sensor secured to an intermediate rod;
determination means for determining a position of the flight control; and
piloting assistance means having at least one electric motor controlled by control means to drive an outlet shaft connected to the link means in parallel with the at least one linkage, the piloting assistance means including at least one ofan electric motor position sensor for determining an angular position of the at least one electric motor, andan outlet shaft position sensor for sensing a position of the outlet shaft.

Abstract
A device for assisting the piloting of a rotorcraft, the rotorcraft having a flight control (10) for controlling a rotor (20, 21) via at least one linkage (35. An additional force is generated by at least one piloting assistance means (100) mechanically linked to the linkage (35. The additional force is a function of the position of the flight control (10) and of an instantaneous force as measured on the linkage (35).
