A method of retrofitting a wing of a fixed wing aircraft. An existing aircraft wing with a main fixed wing portion 20; with a tip end and an existing movable flight control surface 30 connected adjacent the tip end is provided. The existing movable flight control surface is removed from the main fixed wing portion, and a wing tip device 40a and movable flight control surface 30a are selected as a pair to replace the existing movable flight control surface. The selected movable flight control surface has an aerodynamic surface of different shape to the one removed from the wing. The selected wing tip device and movable flight control surface are then fitted to the main fixed wing portion. Also disclosed is a wing where a ratio of the local cord length of the moveable flight control surface to the local cord length of the wind varies in the spanwise direction. Also disclosed is a wing where a camber of an aerofoil section of the wing including the inboard edge of the moveable flight control surface in the neutral position is different than a camber of an aerofoil of the wing just inboard of the inboard edge of the moveable flight control surface.
