Abstract: A method for controlling a play in a flight control surface (12) of an aircraft, implemented by a control system, includes sending a sinusoidal excitation signal; measuring a response signal corresponding to the evolution of a parameter representative of the response of the flight control surface (12) to the sinusoidal excitation signal; processing the response signal to determine the play in the flight control surface (12). The processing includes determining a characteristic variable of an odd harmonic of the response signal other than the first harmonic of the response signal; and determining the play from the characteristic variable with an abacus curve.
