A passenger aircraft including a wing (1) and a wing tip device (3). The wing tip device (3) is moveable between a flight configuration for use during flight and a ground configuration for use during ground-based operations. In the ground configuration the wing tip device is folded downwardly from the flight configuration such that the span of the aircraft is reduced. The wing tip device (3) is connected to the wing along a hinge (9) defining a hinge line (11). The hinge (9) may be arranged to prevent the wing tip device (3) rotating upwardly beyond the flight configuration. The hinge line (11) may be orientated at an angle to the flight direction such that the wing tip device (3) presents a larger frontal area when it is in the ground configuration than when it is in the flight configuration, such that aerodynamic forces urge it to rotate about the hinge line (11) away from the ground configuration and towards the flight configuration.
