In 1976, the Airworthiness Committee proposed a three-tier system comprising dry, normal and substandard runways. It was recognized that
Table 2-1 provides criteria for scheduling runway friction testing for rubber removal. This table is based on an average mix of turbojet aircraft operating on any runway. When any runway end has 20 percent or more wide-body aircraft (e.g., C-5, C-17, C-141, C-130, KC-10, KC-135) in the total aircraft mix, a higher frequency of testing is required;DRAFT 150/5320-12D 3/24/2016 . 130 . runway pavement which were below the minimum acceptable friction level. Test data and 131 surface condition information obtained during this program were given to airport owners so that 132 . they could take proper corrective measures to eliminate runway pavement deficiencies.RT3 ® Friction Testers are used globally to measure changes to surface friction objectively, accurately and precisely in airport and roadway environments.. Operators have real-time feedback on how that surface is changing during the testing period; whether that is in a winter snow and ice event when continual testing is required, or throughout the year after contaminant e.g. rubber .
Friction measuring devices have been serving aerodromes for many years to monitor runway surface friction characteristics. A list of friction measurement devices with corresponding design objective, maintenance planning and minimum friction levels are contained in ICAO Doc 9137 Part 2 ‘Airport Services Manual – Pavement Surface Conditions’.SE222: Runway Excursion - Airplane-based Runway Friction Measurement and Reporting (R -D) The purpose of this Safety Enhancement is to outline research to be conducted by the aviation community (government, industry and . • Objectives of 727 Testing – Friction levels that can be achieved on the winter weather contaminants.Roadwork Industries, an Australian company, is proud to offer aircraft runway & road surface continuous friction testing services. Our Griptester Mark II is the most widely used continuous friction test method for assessing runway surface skid resistance by both civilian and military airfield operators.
Less friction means less aircraft braking coefficient and less aircraft braking response; Runway condition code (RwyCC) values range from 1 (poor) to 6 (dry) For frozen contaminants on runway surfaces, a runway condition code reading of 4 indicates the level when braking deceleration or directional control is between good and medium GripNumber versus test speed. Brisbane Airport's data shows that the runway surface's friction values have a significantly greater change over time as well as variability within the surface any .We use an NAC Dynamic Friction Tester to provide friction testing services for a variety of needs, such as testing for pavement maintenance planning purposes, evaluating for pavement construction project work compliance, new runway and overlay acceptance testing, investigative services and general consulting services.Runway Friction Testing The Vericom VC4000 series Runway Friction Meters are FAA Approved for Airport Winter Safety – as defined in FAA AC 150/5200-30D; Performance Standards for Decelerometers.
