Current aircraft development is driven by a whole set of complex tasks. As new aircraft manufacturers introduce a stronger competition to the overall market, established aircraft manufacturers are under considerable pressure to shorten lead times for aircraft development. Today, during concept definition and specification development, a high degree of uncertainty in the system requirements arises which is propagated through various stages of the development process. Pure requirement based engineering alone is not sufficient to handle the complexity of new aircraft design challenges. Since current design approaches do not consider the impact of this uncertainty on integrated systems, the design specifications are error prone and not validated. In this paper, a method is proposed which makes complex high level systems executable during the very early levels of system design. Generic model components are used to enable system designers to couple functions, architecture elements, resources and performance parameters. As a result, holistic executable specifications on so called Early Conceptual Architecture Level can be derived. A virtual test environment was created to be used for early coverage analyses and testing. The method is demonstrated for the development of a simplified aircraft communication system.
