Aeronautical Research & Technology Areas

A Working Group consisting of NLR, QinetiQ and ONERA constructed the ASTERA taxonomy for aeronautical R&T. This is a hierarchical taxonomy that builds upon existing European structuring efforts, such as the GARTEUR taxonomy and EUROCONTROL's ARDEP taxonomy.

The ASTERA taxonomy has been defined, reviewed and agreed upon by a considerable group of experts from different fields within the European aeronautics community. This has given the taxonomy a strong foundation. Therefore EASN uses and if necessary modifies this taxonomy in order to approach a classification of university activities in the field of aeronautics.
