Abstract: The estimated atmospheric emissions of aircraft operations at a midsized Turkish airport (Adnan Menderes Airport, AMA) for the year 2004 are presented in this paper. The landing and takeoff (LTO) emissions of hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOX) were calculated using the flight data recorded by the State Airports Authority Directorate General. Emission factors from the International Civil Aviation Organization Engine Exhaust Emission Databank were used for different aircraft operation modes such as take-off, climbout, approach, and taxi/idle engine conditions. Total LTO emissions from commercial aircrafts at AMA were estimated as 21 t/y for HC, 138 t/y for CO, and 197 t/y for NOX. Boeing 737-800 type aircrafts have the biggest portions in total emissions (12% for HC, 18% for CO, and 35% for NOX). It is estimated that an increase of 1 min in taxiing time causes an increase of 4.2%, 4.6%, and 0.4% in the amount of HC, CO, and NOX emissions, respectively. Estimations show that the full capacity of aircraft movements at AMA might cause annual emissions to be 176 t/y for HC, 1,184 t/y for CO, and 1,306 t/y for NOX.
