This paper describes the use of Modelica for investigating the multi-physical power behaviour of aircraft equipment systems within the 5th European Community (EC) programme ?Power Optimised Aircraft? (POA) [1]. It gives an overview of the object-oriented structuring of an aircraft systems library which is currently being developed for the physical modelling of conventional and future ?more electric? aircraft systems. An inverse modelling approach is presented, which allows to analyse the non-propulsive power behaviour as a result of given load profiles for the electrical, mechanical, hydraulic and pneumatic equipment systems. In addition the paper describes the definition of assessment criteria, to evaluate and quantify the energy consumption of the aircraft equipment systems. The criteria, their implementation in Modelica and the results from an example are presented.
