As envisioned by the U.S. National Aeronautics and Space Administration (NASA), a real-time systemwide safety assurance (RSSA) is needed to provide a continuum of information, analysis and assessment that supports awareness and action to mitigate risks to safety. According to a 2018 report by the U.S. National Academy of Sciences, NASA’s research plans state that development of an RSSA system for the national airspace system (NAS) will necessitate automating safety assurance of air transportation system components, integrating component-level systems, and reducing the safety assurance cycle time until real-time safety assurance is achieved at the system-of-systems level.
The safety assurance system will combine air traffic and onboard aircraft technologies as well as automated data mining capabilities for continuous safety monitoring and threat prediction.
