Background: Runway friction measuring vehicles are being used in a month-long test at Wallops Island, Va. in a program to devise a standard procedure for predicting the performance of aircraft brakes. Engineers from the National Aeronautics and Space Administration are testing twenty-five devices to measure runway friction under different weather and runway surface conditions. These measurements will be sued to establish a system for runway length requirements to bring a landing airplane to a safe stop. The tests were conducted jointly with the British Ministry of Technology. The Federal Aviation Agency, U.S. Air Force and tire and automobile manufacturers also participated. State highway departments participated in the tests to gather information on a variety of pavement surface conditions. Tests results may have an application in the design of highway surfaces with improved traction for highway safety. Tests were performed on the Landing Research Runway under dry, damp, water-flooded and slush-covered conditions as well as the grooved runway which NASA has designed for airport runways.
