AIRPORT LOCATION OF CITY CENTER AND ITS CONTRIBUTION TO AIR QUALITY
Ervina AHYUDANARI (Surabaya, Indonesia)
ABSTRACT: The contribution of aircraft to the environment is comprised of three stages. First is to the surrounded airport, second to the area of the aircraft climbing path, and third is to the flight level during cruising. The first and the second stages of aircraft contribute to the air quality of urban area next to the airport. Emission in cruising level brings impact on greenhouse gases. To investigate the effect of the location of the airport in contributing the urban air quality, characteristics of aircraft movements are required. The identification of the characteristics of aircraft movements envelopes the flight path from the runway to airborne. The emission of the jet engines of the aircraft is estimated. The emission estimated is then compared to the emission measured in the surrounded airport. The estimation of emission dispersion along the flight path is determined based on the aircraft types and the height of the flight path from the ground. The contribution of the aircraft movements to the air quality can be calculated. The analysis shows that the location of the airport causes emission accumulation due to the climbing process of the aircraft.
