Self-Wetting Systems for Skiddometer

Skiddometer BV11

Vehicle-integrated Skiddometer has a watering system in-built and the trailer can be equipped with a watering system as well.

In addition to 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) such as measuring wet friction at a water depth of one millimetre. 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 that 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 1mm (0.04in) 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.

We offer two options for the trailer watering system.

WMS Self-wetting system

Regular runway calibration with a trailer-based Skiddometer BV11, we offer the WMS Water Measurement System. The WMS system is totally self-contained and offers maximum flexibility, as any vehicle can be used for towing.

The stainless-steel water tank is built from multiple compartments to prevent sloshing. Its capacity is sufficient to make the longest runway measurements with a single run.

Features and benefits include:

  • The most advanced self-wetting system on the market
  • Its robust pumping system automatically provides an always correct uniform water depth of 1mm (0.04in)
  • The stainless steel tank’s volume can be suited and optimised for customer needs
  • Extremely stable, low centre of gravity construction
  • Service free robust construction
  • Can be used to transport Skiddometer BV11 for longer distances such as between different airports

Water On-Board Self-wetting system

The Water On-Board system has the pump mounted on the towed Skiddometer BV11, and water tank in the tow vehicle. The water tank is a 1,000l flexible plastic water sack placed in the vehicle.

Features and benefits include:

  • The robust pumping system automatically provides an always correct uniform water depth of 1mm (0.04in)
  • A cost-effective solution that can be added to any Skiddometer BV11
  • The water tank can be suited to customer needs
