Abstract
A device for regulating the speed of rotation of at least one main rotor of a rotorcraft, which speed is known as the speed NR. Such a rotorcraft comprises at least one manual flight control member for delivering a collective pitch control setpoint C for the blades of the at least one main rotor, the control setpoint C being a function of a current position of the at least one control member; and detector means enabling a current state to be detected from at least two distinct states of the rotorcraft, namely a “ground” state in which the rotorcraft is in contact with the ground, at least in part, and a “flight” state in which the rotorcraft is at least being sustained in the air.
