Abstract: The invention relates to a rotorcraft cockpit having a left seat and a right seat placed side-by-side, a console extending between the seats, two side sticks, one situated to the right of the right seat and the other situated to the left of the left seat, enabling the pilot to control roll and pitch; a flight control system comprising sensors associated with the side sticks and a computer connected to the sensors serves to convert the orders applied by the pilot to the side sticks into signals for controlling actuators in order to vary roll and pitch; a piloting relationship integrated in the computer stabilizes the response of the rotorcraft in roll and in pitch when a side stick is actuated, and maintains the attitudes in roll and pitch at reference values when neither side stick is actuated.

Abstract: A helicopter comprising: a single main rotor for forwards motion and for support; and an anti-torque system comprising: an auxiliary, anti-torque rotor rotated from the engine means of said main rotor and exerting controllable anti-torque lateral thrust; and at least one steering airfoil that is controllable in steering and that generates anti-torque transverse lift. According to the invention, the helicopter includes automatic swivel control means for automatically controlling the swivel angle of said steering airfoil as a function of the collective pitch angle of said main rotor and of the forward speed of said helicopter.

Abstract: A directional and stabilizing device is provided including a faired antitorque rotor, driven in rotation in a transverse aperture formed in a fairing slanted with respect to the vertical by an angle between 0.degree. and 45.degree.. It also includes a "V" empennage fixed to the top of the fairing and the two aerodynamic surfaces of which extend disymmetrically with respect to the vertical plane passing through the top of this fairing, the aerodynamic surfaces being slanted in angular planes between 0.degree. and 45.degree..
