An aircraft wing comprises a main wing with a pivotable trailing edge and a lift-assisting flap on the rear of the wing. The lift-assisting flap is coupled to the main wing and is designed in such a way that in its retracted state, the lift-assisting flap abuts the main wing and in an extended state, the lift-assisting flap forms an air gap with the main wing. The pivotable trailing edge is pivotable in such a way that, by pivoting the pivotable trailing edge, the shape and the width of the air gap are adjustable.
