An aircraft comprises a wing, a wing tip device at the tip of the wing and an actuator. The actuator is arranged to effect movement of the wing tip device 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 comprises a carriage guide, such as a rail, fixed relative to the wing, and a carriage arranged to move along the carriage guide as the wing tip device moves between the flight and ground configurations. The wing tip device is fixed relative to the carriage such that the path of the wing tip device, during movement of the wing tip device, between the flight and the ground configurations, is defined by the shape of the carriage guide. 1. An aircraft comprising a wing , a wing tip device at the tip of the wing and an actuator , the actuator being arranged to effect movement of the wing tip device between:(i) a flight configuration for use during flight and(ii) a ground configuration for use during ground-based operations, in which ground configuration the wing tip device is moved away from the flight configuration such that the span of the aircraft is reduced, a carriage guide, fixed relative to the wing,', 'a carriage arranged to move along the carriage guide as the wing tip device moves between the flight and ground configurations,', 'wherein the carriage carries the wing tip device and', 'the wing tip device is fixed relative to the carriage, such that the path of the wing tip device, during movement of the wing tip device, between the flight and the ground configurations, is defined by the shape of the carriage guide., 'characterised in that the aircraft comprises2. An aircraft according to claim 1 , wherein carriage guide is shaped such that the movement of the wing tip device between the flight and the ground configurations comprises both a rotational component of movement of the wing tip device claim ...
