A flight control surface for an aircraft wing 21 comprises a primary panel 10 mountable to the aircraft wing; and a secondary panel 12, moveably connected to the primary panel such that the secondary panel is moveable between a retracted position, in which a chord length of the flight control surface has a first value and at least one extended position in which the chord length of the flight control surface has a greater value. The secondary panel may be actuated by passing pressurized air through a channel (39, figure 3) or by means of a linear actuator (48, figure 4). There may be a control system operable to place the secondary panel in a high-lift position, a cruise position, or an air braking or lift dumping position.
