3. A Brief Assessment of Aircraft Fuel Consumption and Pollutant Emissions for Departure Operations

The purpose of this study is to assess the quantities of fuel consumed and pollutant emissions of departure aircraft at Istanbul Sabiha Gokcen Airport during taxi operations. To only incorporate information relevant to taxi operations, automatic dependent surveillance-broadcast (ADS-B) data was filtered. The International Civil Aviation Organization’s (ICAO) Engine Emissions Databank was used by considering different aircraft engine types to calculate the fuel and emission parameters. This allowed the calculation of fuel consumption and emission levels, including hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx). The obtained results were then compared to the results of the previously reported model for fuel calculation considering the number of acceleration events. The findings of this study illustrated the variation in the differences between the ICAO emission databank and the model results across aircraft types.
