ANÁLISE DE MACROTEXTURA DE PISTA DE POUSO E DECOLAGEM POR MEIO DA GEOESTATÍSTICA¶
Abstract¶
THE MACROTEXTURE IS AN IMPORTANT OPERATIONAL SAFETY VARIABLE FOR LANDINGS AND TAKE-OFFS, AS IT ALLOWS KNOWING THE TIRE-PAVEMENT ADHESION AND THE CONSEQUENT RISK OF SKIDDING OR AQUAPLANING ON A WET SURFACE. THIS PARAMETER IS ALSO RESPONSIBLE FOR FACILITATING SURFACE DRAINAGE THROUGH RAINWATER RUNOFF. MACROTEXTURE CAN BE CLASSIFIED ACCORDING TO THE TEXTURE DEPTH, IN MM, ON A FIVE-CATEGORY SCALE RANGING FROM VERY CLOSED TO VERY OPEN. THE REDUCTION OF THIS PARAMETER ON RUNWAYS IS ALSO AFFECTED BY THE ACCUMULATION OF RUBBER FROM AIRCRAFT LANDING GEAR TIRES, IN ADDITION TO OTHER CONTAMINANTS, WHICH FILL THE SURFACE OF THE COATINGS, MAKING THEIR TEXTURE MORE CLOSED. THESE MEASUREMENTS ARE TAKEN AT SPATIALIZED POINTS ALONG THE RUNWAY AND, THEREFORE, CAN BE ANALYZED USING GEOSTATISTICS. GIVEN THE ABOVE, THIS ARTICLE AIMS TO VERIFY MACROTEXTURE PATTERNS AND THEIR MODELING THROUGH THE GEOSTATISTICAL METHOD CALLED ORDINARY KRIGING. TO THIS END, THE MACROTEXTURE ANALYSIS POINTS IN THE RUNWAY OF A BRAZILIAN AIRPORT COLLECTED IN 2018 WERE GEOREFERENCED. THE RESULT OF THIS STUDY IS A HEAT MAP WITH THE ESTIMATED VALUES OF MACROTEXTURE FOR THE ENTIRE EXTENSION OF THE RUNWAY ANALYZED. IT IS HOPED, WITH THESE RESULTS, THAT THESE RESULTS WILL ASSIST THE DECISION MAKING OF AERODROME OPERATORS REGARDING THE MAINTENANCE AND REHABILITATION ACTIONS THAT MUST BE ADOPTED TO ENSURE THE ADEQUATE MACROTEXTURE OF THE RUNWAY, PRIORITIZING THE OPERATIONAL SAFETY OF CIVIL AVIATION.
