Measurement of Runway Friction Characteristics on Wet, Icy or Snow Covered Runways.

摘要

Three methods of measuring runway friction characteristics are described and possible usage of the data obtained is indicated. The information presented reflects the current state-of-the-art for measurement and classification of the relative slipperiness of runway surfaces. The three methods described include: (1) The diagonal-braked vehicle test method for measuring stopping distances on paved surfaces, (2) the Mu Meter method for evaluating runway surface characteristics, and (3) the James Brake Decelerometer method for determining runway slipperiness in the form of a friction coefficient.
