Estudo preliminar do comportamento da capacidade de atrito nas pistas de pouso e decolagem do Aeroporto Pinto Martins

Abstract

The airfield’s runways are the most part of the material and financial components on an airport and the pavement friction are directly related to operational risks. International organizations, as the International Civil Aviation Organization, or nationals, as the Agência Nacional de Aviação Civil, use some elements that describes the friction level, like the Coefficient of Friction and the Macrotexture, for the operational control of the runways. Further, studies about the capacity of friction could help on decisions about maintenance and repair operations on airport’s runways. The International Airport Pinto Martins, localized at Fortaleza, Ceará, was the subject to the analysis about these parameters. Through a descriptive analysis and a linear regression model, it was analyzed the individual relation of the landing and takeoff, Macrotexture and the weather, within the rainfall and the average temperature, on the Coefficient of Friction and, moreover, the predictor variables relations within an overall context. The results have showed a relation between the landing and takeoff operations on the capacity of friction degradation and provide a model that can supports in taking operational decisions of maintenance and repair.
