New Rain Repellant Gives Normal Vision During Bad Weather
Bad weather- has lost, another of its hazards for aviation. A new rain repellant, FC-10, a wax-like substance rubbed on aircraft windshields, reduces optical. errors and allows normal visibility of two miles in rainstorms.
FC-10 was developed by Canadian National Research Council scientist Dr. D. F. Stedman, and has been seven years in testing. Early tests showed an average error of five degrees in the pilot’s line of vision through a wet windshield. In a rainstorm a mountain peak might appear to a pilot as much as 200 ft lower than it really was. Treated windshield allows the pilot normal vision and keeps a dry appearance without distortions or ripples. The repellant breaks up rainspots into invisible drops which are swept off by the airstream. It is successful in the heaviest rainstorms, at all airspeeds, and is not nullified by normal de-icing methods. J
