Description: An investigation of three methods for the prevention and the removal of ice on an airplane windshield has been completed. The methods were: electric heating; hot-air heating; and an alcohol-dispensing, rotating wiper blade. The results showed that vision through the airplane windshield could be maintained during severe icing conditions by the use of heat. When put in operation prior to the formation of ice on the windshield the rotating wiper blade prevented the formation of ice. A combination of heated air and a rotating wiper blade would appear to protect against formation of ice on the windshield exterior, to prevent frost on the interior and to provide for the removal of rainfall.
