variants with their own articles=The Hönningstad 5A Finnmark (named for the Norwegian county) was an amphibious flying-boat airliner built in Norway in the late 1940s. The single prototype was operated by the VLS airline, but no orders for additional aircraft were received, and a refined version designated 5A-II was never built. The Finnmark was a conventional high-wing cantilever monoplane with twin engines housed in nacelles on the wings. A specially-designed combination wheel-ski undercarriage retracted into wide sponsons on the sides of the flying boat hull.

This undercarriage (built by Dowty in England) was the subject of patents in Norway, Sweden, and Canada, and was constructed in such a way that the skis would be properly aligned for retraction and extension, and while lowered in flight, but would be free to move under landing forces, pivoting and deflecting to facilitate a smooth landing on rough snow or ice.
