An aircraft (1) comprising a wing (5) the wing having a fixed wing (7) with a wing tip device (9) moveably mounted about a hinge (11) at the tip thereof. The wing tip device (9) is operable between a flight configuration, and a load alleviating configuration for load alleviation during flight. The aircraft (1) comprises a restraining assembly (17) operable between a restraining mode in which the wing tip device is held in the flight configuration using a restraining force such as by a brake (19), and a releasing mode in which the restraining force on the wing tip device is released, such that the wing tip device (9) may adopt the load alleviating configuration. When the wing tip device is in the flight configuration, a biasing member (23) exerts a biasing force to urge the wing tip device towards the load alleviating configuration.
