Typical departure-arrival cycle emissions in international airports of Georgia

Abstract

The role of air traffic, the number and geography of flight worldwide is rapidly growing. Situation in Georgia is not exception of this pattern. Along with positive effect of air traffic such as development of global business, tourism, etc, the negative impacts are worth to mention. Increase of the number and frequency of flights leads to increase of the load on environment both at the local and the global level. Of the local impacts noise and emissions are noteworthy. The objective of this study was to assess emissions of landing – take off (LTO) cycle for international airports of Georgia and suggest mitigation measures for emission reduction. Daily distribution of flights in Tbilisi and Kutaisi international airports has been analysed. Emissions at various stages of the mentioned cycle have been calculated using the International Civil Aviation Organization (ICAO) database and airport specific information. Effect of continuous arrival-departure on reduction of fuel consumption and related emission of main pollutants have been looked into. Additional impact reduction achieved in case of e-taxiing have been considered.
