Runway Friction Testing Systems

It is common knowledge that pavements tend to become slippery to both pedestrians and vehicles when they are wet or flooded or are covered with slush, snow or ice; however, no one yet has a complete understanding of the physical effects causing this slipperiness which in turn can cause accidents. The same applies to aircraft operation on the movement areas i.e. Runways. Previously, the principal aim has been to measure surface friction in a manner that is relevant to the friction experienced by an aircraft tire. Currently, there is no consensus within the aviation industry that this is even possible. To avoid misunderstanding and confusion, measured surface friction should be referred to as measured friction coefficient, which is used to characterize the slipperiness of the runway surface due to presence of contaminants and prevailing weather conditions. The basic friction characteristics, the critical tire -ground contact area, the latter being a part of a dynamic system, influences the available friction that can be utilized by an aircraft. A proper runway pavement, considered as a whole, is required to fulfill the basic functions as to provide adequate bearing strength, to provide good riding qualities, to provide good surface friction characteristics, longevity and ease of maintenance. If any is missing, then it becomes imperative that for aircraft safety, a friction test is accrued out depending on condition of the landing zones of the runway and number of landings.
