Abstract
An aircraft () including a wing () having a wing tip device () configurable between: a flight configuration and a ground configuration in which the span of the wing () is reduced. The aircraft () further includes a lock () for locking the wing tip device () in the flight configuration, and an actuator () for unlocking the lock () and for subsequently actuating the wing tip device () to the ground configuration. The actuator () is a two-stage hydraulic actuator, including a first hydraulic actuator stage () arranged to unlock the lock and a second hydraulic actuator stage () arranged to actuate the wing tip device () to the ground configuration. The first and second hydraulic actuator stages () are arranged in series such that the second actuator stage () is unable to receive a hydraulic input feed until the first actuator stage () unlocks the lock ().
