Technology assessment of future aircraft - Socio-eco-efficiency in conceptual aircraft design

An extended methodology to evaluate and optimize civil aircraft in means of socio-ecoefficiency index is proposed in this study. Here, the aircraft is an element integrated into the air transportation system (ATS), which is described primarily by four main stakeholders: • AIRPORT • OPERATOR (e.g. Airline or private owner) • MANUFACTURER and • AIR NAVIGATION SERVICE PROVIDER. Nowadays, the assessment is mostly driven by economic indicators, which consider environmental impacts peripherally and indirectly (e.g. noise charges, emission tax). In order to expand this evaluation perspective, a procedure is introduced, which considers and combines the 3 pillars of sustainability - SOCIETY, ECOLOGY and ECONOMY in one aggregated value - the SEEindex.
