An aircraft wing 13 has a leading edge 16, a trailing edge 17, a fixed wing portion 23 and a leading edge spoiler 30. The spoiler is rotatably mounted to the fixed wing portion adjacent the leading edge by a hinge 32 and is moveable between a retracted position and a deployed position. In the retracted position the spoiler has a spoiler surface 34 forming a continuous surface with an upper aerodynamic surface of the fixed wing portion, and in the deployed position the spoiler surface is rotated at an angle to the upper aerodynamic surface. In the retracted position the spoiler surface has a first portion forward of the hinge and a second portion aft of the hinge. When a centre of pressure of the local wing section acts on the spoiler surface to provide a moment about the hinge in a first direction the spoiler device is biased to the retracted position. When the centre of pressure of the local wing section acts on the spoiler surface to provide a moment about the hinge in a second direction opposite the first direction then the spoiler device is operable to rotate to the deployed position.
