The International Civil Aviation Organization (ICAO) and the Federal Aviation Administration (FAA) require that all airports with turbojet traffic own or have access to Continuous Friction Measuring Equipment (CFME). This equipment is an effective tool for scheduling runway maintenance, and it can be used to improve operational safety. The most reliable and accurate system for determining actual surface friction values of runways is the Skiddometer BV11 Continuous Friction Measuring Equipment (CFME). Skiddometer BV11 is approved and recommended by the International Civil Aviation Organization (ICAO) and the Federal Aviation Administration (FAA).

Runway friction testing equipment
The Skiddometer CFME system is designed for easy towing with any vehicle. It incorporates features and improvements gained from more than thirty years of experience. The product’s proven lifecycle cost is the lowest in the market. Only a few of the Skiddometer’s parts are exposed to wear, so maintenance and calibration are only needed once a year. The trailer is designed to last for decades and all models can be updated with current parts and the latest computer system.
The Skiddometer BV11VI (Vehicle Integration) is the latest innovation in friction measurement. Its proven technology has been adapted to use a hydraulic lift system with the Skiddometer BV11 and the Skiddometer Touch Screen computer, to provide better vehicle integration.
This new and simple construction allows the Skiddometer unit to be installed easily on any brand of pickup truck available on the market without modifications to the vehicle itself. Friction measurement can take place during the worst possible weather conditions, and now any vehicle can be used to perform the measurement, including safe four-wheel drives designed for such
Besides using the Skiddometer during rain, slush, and snow conditions (operational use), the Skiddometer is also used for checking the runway surface condition and “rubber build-ups” (Runway Calibration), i.e. measuring wet friction at a water depth of one millimeter. This measurement is based on recommendations of the International Civil Aviation Organization (ICAO), the Federal Aviation Administration (FAA), and ASTM standard E 1960 – 98.
Since wet pavement always yields the lowest friction measurements, we offer a self-wetting system which simulates wet pavement surface conditions and provides the operator with a continuous record of friction values along the length of the runway. The attached water pump and nozzle are designed to provide a uniform water depth of 1 mm (0.04 inches) in front of the friction measuring tire. This wetted surface produces friction values that are most meaningful in determining whether or not corrective actions are required.
Skiddometer continuous friction measuring equipment can be equipped with additional features which will add more value to its users. When purchasing Skiddometer trailer or vehicle integration, it will include the unit itself, touch screen measuring computer and cable connection between computer and Skiddometer. Additionally the user can add features to get more value out of the equipment.
