What is CPACS?

The Common Parametric Aircraft Configuration Schema (CPACS) is a data definition for the air transportation system. CPACS enables engineers to exchange information between their tools. It is therefore a driver for multi-disciplinary and multi-fidelity design in distributed environments. CPACS describes the characteristics of aircraft, rotorcraft, engines, climate impact, fleets and mission in a structured, hierarchical manner. Not only product but also process information is stored in CPACS. The process information helps in setting up workflows for analysis modules. Due to the fact that CPACS follows a central model approach, the number of interfaces is reduced to a minimum.

Successfull CPACS Stakeholder Meeting


Spread over Jan. 20 and Feb. 11 2021, the stakeholder meeting on the upcoming CPACS 3.3 Relase candidate took place. It was particularly nice to see the large participation of the community from various research institutions, universities and industry. Among them were, for example, Airbus Defence & Space, Bauhaus Luftfahrt …
