Aircraft windshields heated by means of transparent conductive films

THE safe flight of an airplane depends upon good pilot visibility. Many methods of maintaining clear vision through transparent areas have been used by aircraft manufacturers and operators during the past 10 years, but the development of a transparent conductive film which can be applied to a glass surface promises to offer an ultimate solution to this problem. By means of the transparent conductive film, electric energy can be dissipated as heat close to the surface to be deiced. Excellent deicing characteristics result because of the efficient transfer of heat. Where cockpit space is limited, this system offers the advantage that no bulky controls or equipment are required.
