Abstract: A wing, comprising a structure, an outer skin, and a leading edge device comprising a moveable body with a leading and a trailing edge and a support and actuation mechanism for attaching said moveable body to a structure of a wing and guiding a substantially circular motion of said moveable body, around a hinge line, between a retracted position and at least one deployed position. Said leading edge device further comprises at least one guiding device comprising a track and a follower with a roller. The track follows a substantially circular arc substantially centered on the hinge line. The roller is arranged to be guided by the track and hold down said moveable aerodynamic surface so as to substantially restrict lift-off of its trailing edge from the outer skin of the wing.
