A rotorcraft extending longitudinally along a first anteroposterior plane (P1) separating a first side from a second side of the rotorcraft. Said rotorcraft is provided with at least one main rotor, with an auxiliary rotor, and with at least one airfoil. Said rotorcraft includes a processor unit connected to mover means for pivoting said airfoil, the processor unit being connected to a first measurement system for measuring a current value of a speed parameter of the rotorcraft and to a second measurement system for measuring a current value of a power parameter (W) of said power plant for adjusting the deflection angle of the airfoil.
