What's Happening?
A recent study has refined the modeling of aircraft landing-takeoff (LTO) activities to better estimate emissions and fuel consumption. The ALTFEM model calculates dynamic time-in-mode for each flight, offering more accurate insights into aviation emissions. The study found that 20% of airports contribute to 89% of emissions, with high concentrations in economically developed regions. The model aims to improve local air quality assessments and guide airport-specific emission reduction strategies.
