Abstract
An aircraft wing assembly including a wing having a main body 5 and a movable portion 6, so that the wing may be folded when taxiing. A lighting system is provided with a light source 9; a light emitter 11 arranged on one of the main body and the movable portion, and a light guide 10 arranged to transmit light from the light source along a path between the main body and the movable portion to the light emitter. The provision of a light guide between the light source and the emitter allows for light to be transmitted to the emitter across the joint 8 between the wing main body and the movable portion. Thus, lighting on the wing may be provided without the need to provide electrical wiring across the joint. A single light source 9 may be employed to illuminate multiple light emitters 11, 13 on the wing.
