The Polar light utility monoplane built by Wideröe’s Flyveselskap og Polarfly A.S. in 1948, was designed by Birger Hönningstad to a specification prepared by the company. This called for an aircraft suitable for carrying a pilot and five passengers or cargo, capable of operating from wheels, floats or skis. Only one example of the Polar was built.
The Polar is of mixed construction, the plywood and fabric covered wing having two spruce spars and spruce ribs, and the fuselage has a welded steel-tube framework with a spruce and duralumin superstructure covered by light alloy panels forward and fabric aft.
Only one C.5 Polar was built, which was employed by the Wideröe company.
