As is true with many of Europe's airports, Luxembourg's Findel International Airport is found in close proximity to the nation's city center (6km). In this paper we focus on the Cargolux Airlines' airfreight operations and report on a multi-cost problem that has been developed so that costs are shared between the company, the state and the private citizen. Here we search for a cost effective solution using the night noise metric L_N. A best (lowest shared cost) solution among a set of predefined scenarios is found. The approach used is consistent with the legislative framework of the European Union Directive on Assessment and Management of Environmental Noise and the European Balanced Approach. We also discuss the potential affect of background noise and noise over threshold, previously omitted in the shared cost study. A web-based aviation scheduling tool is also presented. The tool allows an end-user, the company, the regulating authorities, or interested stakeholders, to adjust tunable parameters, including aircraft scheduling, route choice and arrival/takeoff parameterization.
