Avionics platform development, integration and test as well as the management of data during the development process is a complex task. Each step in the development but also during operation and adaptation of the platform introduces new artefacts to be managed. AvioNET is developed by the Institute of Aircraft Systems Engineering (FST) of Hamburg University of Technology (TUHH) and presented in this paper. It combines methods to create a highly automatable and interconnectable, model-based tool chain for avionics development considering different development phases and roles.
