An aircraft (1) comprises a foldable wing (3), the wing (3) comprising
an inner region (5) and an outer region (7), such as a wing tip. The outer region (7) is moveable relative to the inner region (5) between a flight configuration and a ground configuration in which the span is reduced. The aircraft comprises a control system (13) and a control interface (15). The control interface (15) comprises a selector (19) for selecting the desired configuration of the outer region (7), and is arrange to provide: a first output, such as a light, when the flight configuration is selected and the outer region is in the flight configuration; a second output, such an amber light, when the ground configuration is selected and the outer region is in the ground configuration; and a third output, such as a red light, when the outer region is not in the selected configuration. |
