The invention concerns a method for the determination of an azimuth angle for servicing purposes (αw) of a wind power plant with a machinery housing that is rotatable on a tower through an azimuth angle (α) and a rotor that is rotatable on a machinery housing through a rotor angle (δ) such that a plurality of combinations of rotor angles (δ) and azimuth angles (α) is adjusted, that are determined at the rotor subject to the influence of a turbulent wind field, which is effecting torques, for the adjusted combinations of rotor angles (δ) and azimuth angles (α) and the associated azimuth angle (α), a torque envelope of the torque-azimuth angle associations is determined, surrounding areas (U(α)) with comparable sector sizes of the azimuth angle (α) are generated and associated magnitude values of the torque envelope are determined, a surrounding area (U(αw)) with magnitude-wise smaller torque envelope values than the neighboring surrounding areas is selected and the azimuth angle for servicing purposes (αw) is determined within the selected surrounding area (U(aw)).
