The five basic elements affecting runway traction for jet transport aircraft operation are identified and described in terms of pilot, aircraft system, atmospheric, tire, and pavement performance factors or parameters. Runway traction is so affected by the interaction of these elements that it becomes an impossible task to discuss the effects of each element individually. For this reason, this paper discusses runway traction under the general headings of dry, wet and flooded, and snow and ice conditions. Where possible, research results are summarized, and means for restoring or improving runway traction for these different conditions are discussed.
