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.
