Calculation of HC, CO and NOx from civil aviation in Turkey in 2012
To meet the growing demand for air transport, airline companies doubled their aircraft numbers in Turkey, where civil aviation activities have shown great development in recent years. This increase in aircraft numbers resulted in an emission problem. Considering its impact on regional air quality, the growing emission amounts are at a non–negligible level. We especially take the busiest airports in Turkey into account, as these airports are generally located in widely populated areas. In this study, HC, CO, and NOx emission during the LTO for the selected five busiest airports were calculated by taking the 2012 domestic data of: 1) the General Directorate of State Airports Authority in Turkey; 2) EUROCONTROL's average taxi time; 3) emission factors of ICAO engine datasheets. The calculated emission amounts are 215 tons/year, 1,483 tons/year, 1,417 tons/year, HC, CO, NOx respectively and the biggest emission factor is found to be as CO. Among the airports, Istanbul Ataturk Airport has the biggest polluting emission ratio.
