The concept of a Virtual Iron Bird for the modelling of aircraft system architectures is presented. This platform can be used to evaluate and assess more-electric aircraft system configurations by simulations. For these purposes an object-oriented model library is set up by use of the modern multi-physical modelling language Modelica. Besides the design of the library, an inverse modelling approach is shown allowing to analyse the behaviour and power consumption of aircraft systems. In order to determine accuracy estimates of the overall results, Monte Carlo simulations of uncertainty models are performed, which identify the statistical distributions of the results and assessment criteria
