6875 RUNWAY FRICTION TESTER (RFT) The Dynatest 6875 Runway Friction Tester (RFT) is designed to measure runway friction characteristics for both pavement maintenance and operational purposes. Pavement maintenance to address runway friction concerns may be required due to rubber contamination or weathering of the pavement surface. Operational friction testing is performed to ensure adequate friction to land aircraft and may be performed during heavy rain, ice, slush, or snow as allowed by FAA regulations. It is a fully instrumented pickup truck available on either two-wheel or four-wheel drive. It uses a Dynatest Two-Axis Force Transducer mounted on a retractable fifth wheel assembly. The vehicle is driven along the runway at a controlled speed, where the measuring wheel record the frictional forces between the runway surface and the device. The data is then analyzed to determine the runway’s friction coefficient, which is a measure of the surface’s ability to provide traction to an airplane’s tir
