  • Abstract:
    For many years, the aviation community has struggled with runway friction reporting practices. Airport operations personnel, in taking on the responsibility for conducting friction measurements during winter storms, work diligently to keep up with rapid changes in the weather. Airport operators should know how to provide pilots with acceptable runway condition reports that

    represent the current status of runway surfaces covered with ice and/or snow, and how these reports aid in predicting aircraft performance under these conditions. Air traffic control (ATC) should provide standard reports to pilots and must have an agreement with the airport operator on what standard information the reports are to contain, and how the reports are to be disseminated.

    Airlines need to provide instruction and standardized guidelines to their pilots on the use of the runway surface reports. Pilots interpret what the reports and friction numbers mean to their aircraft performance for these conditions.

    To have both current and reliable information during such circumstances, the aviation community needs well-established acceptable guidelines. Airport personnel should maintain a high level of awareness to rapidly changing conditions and recognize these changes in order to provide pilots with the most reliable information concerning runway surface conditions during inclement weather conditions.

    Therefore, Federal Aviation Administration (FAA) documents must be coordinated so that they give consistent guidelines for airport operators, pilots, ATC, and the airline industry. This document produced by the FAA/Industry Winter Runway Friction Measurement and Reporting Working Group, is designed to provide an overview of current information on the present guidance, practices, and procedures for reporting runway pavement surface conditions during winter operations at airports. It contains recommendations on the desirability of providing the best procedural consistency and standardization and discusses the available means to implement the guidance that will result in improved aviation safety at airports during hazardous winter conditions.

    Participants of the working group include representatives from the FAA, National Aeronautics and Space Administration (NASA), Transport Canada, Airports Council International (ACI), American Association of Airport Executives (AAAE), Air Transport Association (ATA), Regional Airline Association (RAA), Air Line Pilots Association (ALPA), aircraft manufacturers,

    and a technical advisor. Research and development credits for this paper go to: Mr. Francis Anderson, Transport Canada; Mr. Rick Marinelli, FAA; Mr. Tom Morrow, technical advisor; Mr. Glenn Morse, ATA; Mr. Wes Te Winkle, FAA; Mr. Jerry Wright ALPA; and Mr. Thomas Yager, NASA.
