1. A method for adjusting the play in a high-lift system of an aircraft, wherein the high-lift system comprises a drive unit, a driveshaft that is connected to the drive unit and several driving stations that are distributed along and mechanically connected to the driveshaft and respectively comprise a rotary actuator with a housing and a drive lever mounted therein, wherein said drive lever extends radially from a rotational axis of the rotary actuator and is coupled to a pivotably mounted flap by a connecting link, and wherein the respective drive levers are moved by rotating the driveshaft with the aid of the drive unit and the flaps are thereby displaced between a retracted and an extended position, the method comprising:
displacing the driving stations into a first position;
disengaging the mechanical connections between the driveshaft and the driving stations in the first position;
displacing the individual drive levers in the direction of an extended position by mechanically driving a gear input of the associated rotary actuator such that the individual drive levers come into mechanical contact with a stop in a second position, which is spaced apart from the first position in the extending direction;
rotationally fixing the gear inputs of the rotary actuators;
adapting the length of the connecting links in such a way that a position of the associated flap corresponding to the position of the stop is reached; and
reconnecting the driving stations to the driveshaft.
