Abstract

This study examines the impact of Intelligent Transportation Systems (ITS), focusing on Performance-Based Navigation (PBN), on the operational efficiency of Brazilian commercial aviation. Using ANAC microdata from the 14 busiest domestic routes between 2010 and 2024 (≈544,000 completed flights), we estimate the association between PBN adoption and flight time, fuel consumption, and CO₂ emissions. Multiple linear regression models with robust errors control for route distance and aircraft type, and a robustness specification applies log-transformed flight time with route fixed effects. Results indicate that higher PBN adoption is associated with average reductions of 2,6 minutes in flight time, 27,7 kilograms of fuel, and 87,6 kilograms of CO₂ per flight. While these per-flight effects are modest, their aggregation across high-frequency routes translates into substantial operational savings and avoided emissions. The findings highlight the strategic importance of ITS/PBN in enhancing efficiency, supporting sustainable air transport, and informing policies aimed at decarbonization in emerging economies.
