In this study, first we compare three charging scenarios by computing the Unit Rate values to be set by each ANSP located in the CEATS area. Then we analyse the impact that such Unit Rate values may have on the Aircraft Operators flying in the CEATS area. We conclude that, without a compensatory mechanism, the pol- icy of considering different Unit Rates for each ANSP in the area would adversely affect the re- gional carriers and all the airlines based in the CEATS area since the CEATS Unit Rate turns out to be significantly lower than the Unit Rates of the national ANSPs controlling the lower airspaces.

We consider the interdependence of the slots at different airports, and we maximize the efficiency of the system. Through an experimental analysis we quantitatively assess the cost imposed by grandfather rights, which constitute one of the main principles of the current slot allocation mechanism. Moreover, we introduce

It is an extension of the problem currently tackled for allocating airport slots: it deals with all airports simultaneously and it enforces the respect of airspace sector capacities. By solving this novel problem, the system may overcome some major inefficiencies that characterize the current slot allocation process. We tackle the

The tool for integrating heterogeneous data is a model of artificial intelligence; fuzzy logic is applied to multi-criteria decision support systems. The results obtained

During and after the aviation breakdown of April-May 2010, communication between the involved stakeholders was recognized as a major concern. Due to the complexity and multidisciplinary nature of the topic, a great number of actors is involved, which often have little interaction outside these exceptional events. In this work, we aim at identifying the relationships between the stakeholders involved in aviation management during eruptions, as well as their needs and priorities. We perform an anonymous on-line survey, focused mainly on the use of tephra dispersal models for civil aviation purposes. We collect feedback on recent developments including our current impact assessment research, which produced a GIS-based software tool to estimate impacts on aviation based on tephra dispersal forecasts. Answers allow identifying stakeholders’ requirements on ash dispersal forecasts and its use for aviation management purposes. We underline the main differences between three homogeneous groups (aviation managers and employees, modellers and field scientists, other stakeholders) and identify main end-user requirements for developing tools similar to ours. This work provides useful insights for the development of tools to support aviation stakeholders during volcanic eruptions.
