A system for modifying the chord of a wing 1 of an aircraft comprises a flap 10 and an actuating system configured to translate the flap 10 in a direction substantially parallel to the chord of the wing, between a first position (figure 1a) and a second position (figure 1b), such that the wing has a first chord length when the flap 10 is in the first position, and a second different chord length when the flap 10 is in the second position. The actuating system is configured to move the flap to a deployed position (figure 4a) wherein the flap 10 is translated aft and rotated about a longitudinal axis of the flap, relative to the first position. The system comprises a lower shroud 30 configured to form a substantially continuous surface between a lower surface of the wing and a lower surface of the flap when the flap is in the first position and in the second position. The lower shroud 30 may move up to contact an upper shroud 40, when the flap 10 is in the deployed position, creating a slot 60.
