Abstract: This paper aims to evaluate the vertical profile efficiency of arrival traffic at Trabzon Airport in terms of fuel consumption, carbon dioxide (CO2), hydrocarbon (HC), carbon monoxide (CO), and nitrogen oxide derivatives (NOx). For this purpose, 3-deg descent profiles were created using the parameters obtained from real flight data under the near idle thrust and clear configuration restrictions and these were then compared to the reference real flight profiles. The cruise section was also considered while comparing the designed continuous descent profiles to baseline scenarios. According to the results of our analyses, the altitudes at which landing traffic deviates from the optimum profile is especially around 6000ft and after the top of descent point. It was not possible to note a high level of vertical inefficiency in the vertical profile of arrival traffic, however, holding maneuvers, waypoint restrictions play an important role in overall descent time, fuel consumption, and emissions. © 2021 Elsevier Ltd
