Methodology for ecological and economical aircraft life cycle analysis

This paper presents an approach for the life cycle analysis of an aircraft. Especially in the early design phases no valid methods to analyze and optimize civil aircraft in economic, ecological and socio-economic perspectives exist. The method is applicable in the public domain without company's sensitive information and allows analysis from an exterior view, e.g. to support political decision making. This paper mainly focuses on the production phase. To overcome the main challenges like low data availability in public domain, an integrated top-down and bottom-up procedure of existing methodologies has been chosen.
