Abstract
An aircraft (102) having a wing assembly (101) including a fixed wing (105) with a wing tip device (103). The wing tip device (103) is moveable between: a flight configuration; and a ground configuration. The outer end of the fixed wing (105) terminates at an outer rib (115), and the inner end of the wing tip device (103) terminates at an inner rib (117). The outer and inner ribs (115, 117) are located on opposing sides of an interface between the fixed wing (105) and the wing tip device (103). The fixed wing-skin (119) terminates inwardly of the interface, but the outer rib (115) has a surface-forming portion (127) forming an extension of the fixed wing-skin towards the interface. The wing tip device-skin (121) terminates outwardly of the interface, but the inner rib has a surface-forming portion (129) forming an extension of the wing tip device-skin towards the interface.
