Using Linux in Safety Critical Systems, up to DAL-D or can we go higher?
Olivier Charrier
Principal Technologist - Functional Safety, Wind River
Innovation is often prototyped using Linux, for example artificial intelligence (AI), analytics, predictive maintenance, etc. However, when Safety Certification is involved, is it possible to stay with Linux or is migration to another operating system with an existing safety pedigree inevitable, in order to pass formal Safety Certification?
The presentation will review the current approach used today for achieving RTCA DO-178C / EUROCAE ED-12C DAL-D, and will highlight the associated challenges, from the definition of the requirements up to the associated tests and the traceability linking all the pieces together.
Then we will review ongoing initiatives by the ELISA (Enabling Linux in Safety Applications) project specifically seeking to achieve higher levels of Design Assurance. We will also consider how different working groups and associated activities are progressing towards the goal of using Linux in safety-critical systems.
