Abstract: The invention relates to a system (10) for controlling a water landing of an aircraft comprising at least one detection device (12, 14, 16, 18), which is adapted to detect at least one signal suitable for recognizing an imminent water landing of the aircraft. A control unit (20) is adapted to receive the at least one signal suitable for recognizing an imminent water landing of the aircraft and to evaluate said signal on the basis of at least one predetermined recognition characteristic that characterizes a water landing of the aircraft. The control unit (20) is also adapted to control a closing device (24) associated with an opening (22) in such a way that in the event of a water landing of the aircraft the entry of water into an interior area of the aircraft through the opening (22) is prevented if the control unit (20) recognizes that a water landing of the aircraft is imminent on the basis of the at least one signal and the at least one recognition characteristic.
