The main purpose of this study is to explore how aircraft noise charges can be calculated. In order to give an empirical example of how such calculations would work in practice, we estimated the noise charge per landing at C.K.S. international airport. We explored the charging problem both from the legislative perspective and technical perspective. The legislative side includes a survey of the related regulations of Japan and Taiwan. We compared the differences and develop the legislation framework of our country, pointing out that legislation is an important issue and should be improved as soon as possible. The technical side of airport noise charge problem can be considered as two sub-problems : cost estimation and cost allocation. For cost estimation, three approaches were discussed : via the real expenditure, via the regulated expenditure, and via the property depreciation. The first two were applied to the C.K.S. case. For cost allocation, based on the existing formulae being applied by various airports worldwide, we categorized these noise charge formulae into two major models : Linear Model and Exponential Model. Both models were used to calculate the noise fee for the C.K.S. international airport. Numerical results of our case study showed that two models have similar outcomes for heavy and noisy aircraft or light and quiet ones, and dissimilar outcomes for heavy but quiet aircraft or light but noisy ones. For example, a typical B747-400 would be charged NT$ 8,524 per landing for Linear Model and NT$ 8,161 for Exponential Model, but a B737-222 would be charged NT$ 2,621 for Linear Model and NT$ 5,094 for Exponential Model. In comparison to Linear Model currently being employed by our country, Exponential Model seems to have better quality to reflect the noise impact caused by one aircraft. When Exponential Model is applied, we suggest that the value of transformation coefficient should be set between the range that reflects human perceptions, and a time period penalty should be included in the noise index of the aircraft for each operation. To eliminate the impact of time-lag effect, we recommend a charging system with fixed calculation formula and adjustable unit price.
