The type of rain repellents that can be applied in flight were evaluated to determine their effectiveness in improving windshield visibility during precipitation. The repellents were flight-tested on the FAA's Boeing 720 using the Boeing Rain Repellent Application System installed for the copilot's windshield. Comparative 16 mm. motion pictures were obtained of the pilot's and copilot's windshields during approaches to landing in precipitation. Laboratory tests were conducted to determine the effects of these repellents on glass and aluminum over a prolonged period and also to determine the repellents' freezing points. It was concluded that the Boeing Airplane Company's Type 1 and Type 3 rain repellents offer substantial improvement in windshield visibility during rain and, for light rain conditions, are most effective when used in conjunction with windshield wipers. It was also concluded that the U. S. Navy's Foster D. Snell, Inc. Rain Repellent was not compatible with the Boeing Application System and, therefore, could not be properly evaluated. (Author)
