- Instrumented Test Aircraft to Be Used for Evaluating Braking Friction on Runways with Full-Depth Trapezoidal -Shaped and FAA Standard Runway Grooving Under Wetted Conditions. - Aircraft Brake Testing to be Conducted at Speeds of 140 Knots or Greater with 3 Seconds of Friction Limited Braking Minimum. Federal Aviation . 19 Administrationallow runway friction to be treated as an operational variable. In 1976, the Airworthiness Committee proposed a three-tier system comprising dry, normal and substandard runways. It was recognized that the operational distinction between normal and substandard wet runways posed problems which was not yet solved.
International Civil Aviation Organisation (ICAO) standards require runways to be maintained so as to provide good friction characteristics. Every state has to define minimum friction levels below which a runway is considered to be ‘Slippery When Wet’, meaning restrictions apply to aircraft performances.
So, runway friction testing plays a crucial role in maintaining the safety of aircraft operations and preventing accidents caused by inadequate braking performance.
