A method of controlling a deflection angle of pitching stabilizer means for an aircraft. The method includes a preliminary stage for preparing at least one control relationship delivering a setpoint angle that is to be reached by the deflection angle as a function of at least one flight parameter of the aircraft and of an incidence parameter of the pitching stabilizer means. During an operational stage an operational stage (STP2), a “flight” value is determined for each of the flight parameters, a “setpoint” value is determined for the incidence parameter, a setpoint angle is determined by inputting the flight values and setpoint value into the control relationship, and at least one actuator is actuated in order to cause the deflection angle of the pitching stabilizer means to reach the setpoint angle.
