New challenges in certification for aircraft software

John Rushby
2011 Proceedings of the ninth ACM international conference on Embedded software - EMSOFT '11  
We outline the current approach to certification of aircraft software, and the rôle of the DO-178B guidelines. We consider evidence for its effectiveness and discuss possible explanations for this.  ...  We then describe how changes in aircraft systems and in the air traffic system pose new challenges for certification, chiefly by increasing the extent of interaction and integration.  ...  One, relatively new, approach requires the "applicant" to develop a safety case [8, 18] that makes explicit the claims, evidence, and argument for the safety of the system; the general content or form  ...

On Software Certification: We Need Product-Focused Approaches [chapter]

Alan Wassyng, Tom Maibaum, Mark Lawford
