There is provided an aircraft wing (5) having a fixed root part (7) hingedly connected to a moveable tip part (9). The tip part (9) is configured to pivot relative to the root part (7) about a substantially horizontal axis, between a load-alleviating configuration in which the tip part (9) is oriented relative to the root part (7) such that at least one of the upper and lower surface of the tip part (9) is positioned away from the respective surface of the root part (7) and a flight configuration in which the upper and lower surfaces of the tip part (9) are continuations of the upper and lower surfaces of the root part (7). The shape of the tip part (9) is controllably switchable between a cruise shape in which the tip part (9) has positive camber and a recovery shape in which the tip part (9) has negative camber.
