💡Wing-in-ground (WIG) craft are supported in their main operational mode solely by aerodynamic forces, which enable them to operate at a low altitude above the sea surface but out of direct contact with that surface. |
Accordingly, their arrangement, engineering characteristics, design, construction, and operation have a high degree of commonality with aircraft characteristics. However, they operate with other waterborne craft and must necessarily utilize the same collision avoidance rules as conventional shipping.
WIG craft is a multimodal craft which, in its main operational mode, flies by using ground effect above the water or some other surface, without constant contact with such a surface and supported in the air, mainly, by an aerodynamic lift generated on a wing (wings), hull, or their parts, which are intended to utilize the ground effect action.
