Resumo
The growing demand for air transport, which increased between 2010 and 2019, highlights the importance of improving the safety of landing and takeoff operations. This study analyzed the functional classification of runways using longitudinal roughness indices (International Roughness Index - IRI, Boeing bumping Index - BBI, and Runway Roughness Index - RRI) for airport pavements, comparing them to each other. The widely used IRI is considered inadequate by some authors because it does not adequately account for the physical and aerodynamic properties of aircraft. The BBI, developed by Boeing and the FAA, identifies surface irregularities in pavements but is limited in evaluating consecutive events. In response to these limitations, the FAA developed the RRI, which considers vertical accelerations in the cockpit of Boeing 737-800 aircraft at a constant speed of 185 km/h. The study utilized profile data from a runway, analyzed with ProFAA software and organized into 200-meter sections. Descriptive analysis showed that the RRI has distinct characteristics, with lower averages than the IRI and BBI. The IRI revealed greater variability on the runways, while the BBI indicated lower sensitivity to defects. It is concluded that the RRI provides greater flexibility in maintenance decision-making, balancing the sensitivity of the IRI with the tolerance of the BBI.
