"IATA forecasts an annual air traffic growth of at least 5% for the coming years. As a consequence the capacity overload of current airports has considerably grown. The huge shore lines and number of islands in Europe which were increased by the new EC member states offer a great potential for an international air traffic system uisng seaplanes and amphibians. With these vehicles new traffic routes can be developed with the advantage of using natural landing strips. By using amphibians direct connections from shorelines to airports can be realised. The mobility of a large population will be improved. Operators and entrepreneurs interested in starting new seaplane businesses report about missing modern airplanes, international standards and rules and missing expertise of various stakeholders. Based on this preliminary analysis the proposal aims to investigate the today´s seaplane situation and to evaluate the weaknesses and strenghts and to elaborate a set of concepts and requirements for a future seaplane air transportation system for "Improving passenger choice in air transportation" including technical requirements for " new vehicles". The elaboration of new concepts shall be based on existing experiences and its evaluation and on research work focussing on future oriented traffic system concepts including the integration into a sea/air/land traffic chain. In order to collect all available experiences and ideas as a basis for effective future traffic concepts workshops shall be organized by bringing together all relevant stakeholders. One workshop shall be arranged in the Mediterreanean (Greece, Italy or Spain) one in Poland and one in GB or France. The workshops will support the dissemination of the SA results and of FP7 and ACARE policies, too. Beside the reqirements for the new transport system a road map for needed regulatory issues will be compiled supported by EASA. The partners coming from seaplane operation, amphibian industy and from aeronautical research guarantee a successful SA."
