    摘要: A wing assembly (200) for an aircraft (1) has an actuation assembly configured to move a wing tip device (300) between a flight configuration and a ground configuration. The actuation assembly comprises at least two linear actuation devices (530, 540) mounted within the wing assembly (200). A wing (210) and a wing tip device (300) for the wing assembly (200), and an aircraft (1) comprising the wing assembly (200), wing (210) or wing tip (300), are also described.
