1. An aircraft comprising an aircraft wing, the aircraft wing comprising a fixed wing and a wing tip device at the tip thereof, wherein the wing tip device is configurable between: (i) a locked 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 locked flight configuration such that the span of the aircraft wing is reduced, the aircraft wing further comprising a locking mechanism for locking the folding wing tip device in the locked flight configuration, the locking mechanism having a longitudinal axis and comprising a first part associated with one of the fixed wing and the wing tip device, and a second part associated with the other of the fixed wing and wing tip device, the locking mechanism having a locked configuration, in which the first part is received in the second part such that the first part is prevented from being withdrawn from the second part along the longitudinal axis of the locking mechanism, and an unlocked configuration, in which the first part is received in the second part such that the first part is free to be withdrawn from the second part along the longitudinal axis of the locking mechanism, wherein the locking mechanism is moved between the locked configuration and the unlocked configuration by rotation of at least one of the first part or second part around the longitudinal axis of the locking mechanism. |
