Title: Reducing Certification Granularity to Increase Adaptability of Avionics Software,
Abstract: A strong certification process is required to insure the safety of airplanes,
and more specifically the robustness of avionics applications. To implement
this process, the development of avionics software must follow long and costly
procedures. Most of these procedures have to be reexecuted each time the
software is modified. In this paper, we propose a framework to reduce the cost
and time impact of a software modification. With this new approach, the piece
of software likely to change is isolated from the rest of the application, so
it can be certified independently. This helps the system integrator to adapt an
avionics application to the specificities of the target airplane, without the
need for a new certification of the application.
