An aircraft wing 300 comprising a laminar flow control (LFC) system comprising a conduit 321 drawing air from a leading edge exterior surface 309 and structurally supporting Krueger flap 315 weight (fully or partially supporting the aerodynamic load exerted on the Krueger flap). Preferably the conduit comprises an outer duct 307 concentrically surrounding an inner duct 301, the outer duct providing cold exterior air, insulating the inner duct providing hot air for wing skin ice protection. A method of at least partially shielding perforations 309 in an aircraft wing leading edge region from debris (e.g. insects), wherein an aerodynamic surface 315 moves to change airflow path over the wing. The perforations provide apertures for drawing air via a duct 321 of a boundary layer control system. At least part of the aerodynamic surface movement is structurally supported by a structure 330 (e.g. bracket) mounted to the duct.
