Determining of Aircraft Engine Greenhouse Gas (CO2, CH4 and N2O) Emissions from the Landing and Take-Off Operations Around the Airport Area

Abstract

Recently, environmental concerns arising from aviation activities have increased, and studies on the environmental aspect of aircraft operations within the concept of sustainable and cleaner aviation have become one of the important research topics. In this study, the greenhouse gas (GHG) Emissions, namely CO2, CH4, and N2O pollutants emitted to the environment during the landing and take-off operations in the International Eskisehir Hasan Polatkan Airport (LTBY) of aircraft engines were analyzed with the help of predictive approaches. Additionally, the average jet-fuel consumptions of these aircraft were determined. Calculations were performed in point of the method of the Intergovernmental Panel on Climate Change (IPCC) and performed with the Tier-2 predictive approach. According to results, it has been obtained that the Airbus 321 (A-321) series aircraft has the highest pollution with a value of 762495 kg/y of GHG. Furthermore, it has been observed that approximately 1127710 kg/y of CO2, 48.14 kg/year of CH4, and 39.77 kg/y of N2O were released into the environment. On the other hand, the total value of jet-fuel consumption during the landing and take-off operations of these aircraft is calculated to be an average of 357500 kg/y. In this regard, it has been determined that the Boeing B767-300 series aircraft (B763) is the most inefficient type of aircraft depending on the fuel consumption by performing a correlation between the parameters of average jet-fuel consumption and total landing and take-off count.
