An aircraft can include a wing (42) with a leading edge (64) and a trailing edge (66). The wing has a main body (74) and movable control surfaces (80, 82) coupled to the main body. The wing (42) generates lifting forces when the aircraft is in flight. The movable control surfaces can be used to control the generated lifting forces. A spanwise flow inhibitor (70) extends from the outer wingtip (96) of the wing. At least one gurney flap (100, 102) extends generally downwardly from at least a portion of the trailing edge (66) of the wing. The flap at least partially counteracts a change in center of lift attributable to the spanwise flow inhibitor.
