SAVOIR has produced a set of generic specification under the form of documents, based on some physical architecture of equipment that was state of the art at that time. The new functional model based approach is more based on functional chains and models. It is expected that modelling the SAVOIR avionics architecture and generic specification using the MBSE techniques, in particular Arcadia method and Capella tool, will allow to have an innovative standpoint on the SAVOIR standardisation. In particular, it will give to the avionics community some generic or reference models that they could use to bootstrap the use of MBSE for their avionics, this will help introducing MBSE in avionics.
