Title: Preliminary Evaluation Of Noise Reduction In Sofia By Implementing Continuous Descent Approach Procedures For Landing At Sofia Airport
Keywords: aircraft noise, noise mitigation, continuous descent approach

Abstract: This work is a part of a more comprehensive study on the environmental effects of the Continuous Descent Approach (CDA) method of aircraft descent and landing if implemented at Sofia airport. An analysis of the possibility to reduce noise levels in the vicinity of Sofia airport by implementation of the CDA is performed. Also a preliminary quantitative estimate of this noise reduction is calculated. The results show that for the majority of the aircraft types landing in Sofia airport CDA will not affect the noise levels if landing on runway 09 and it will lead only to minor noise reduction if landing on runway 27. These conclusions do not undervalue the other benefits of CDA and they are valid only for airplanes for 100 - 180 passengers, that are most widely used from Sofia airport, but not as general.
