An aircraft comprises a wing (1), a wing tip device (3) at the tip of the wing and an actuator (5). The actuator (5) is arranged to effect movement of the wing tip device (3) between a flight configuration for use during flight and a ground configuration in which the wing tip device is moved away from the flight configuration such that the span of the aircraft is reduced. The aircraft (2) comprises a carriage guide (15), such as a rail, fixed relative to the wing (1), and a carriage (14) arranged to move along the carriage guide (15) as the wing tip device (3) moves between the flight and ground configurations. The wing tip device (3) is fixed relative to the carriage (14) such that the path of the wing tip device, during movement of the wing tip device (3), between the flight and the ground configurations, is defined by the shape of the carriage guide (15). |
