An aircraft wing 10 wing incorporating an active flow control (AFC) device 25. The AFC device comprises a fluid chamber 26 housed in the wing providing a conduit for receiving fluid and accommodating the fluid at elevated pressure. Forward and rearward fluid channels 32 and 38 having respective inlets 34 and 40 and outlets 36 and 42 are also provided, wherein the inlets are in fluid communication with the fluid chamber and the outlets emerge on the upper surface of the wing at or adjacent the leading edge. A valve assembly 28 allows the channels to be opened and closed as desired. During flight, fluid at elevated pressure can be supplied to the fluid chamber and released through either the forward or the rearward fluid channel or both, so as to influence the air flow, e.g. to reduce or increase lift, or to equalize pressure in the air stream direction.
