The National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, nongovernmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Marcia McNutt is president.
The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. C. D. Mote, Jr., is president.
The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president.
The three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. The National Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine.

Consensus Study Reports published by the National Academies of Sciences, Engineering, and Medicine document the evidence-based consensus on the study’s statement of task by an authoring committee of experts. Reports typically include findings, conclusions, and recommendations based on information gathered by the committee and the committee’s deliberations. Each report has been subjected to a rigorous and independent peer-review process and it represents the position of the National Academies on the statement of task.
Proceedings published by the National Academies of Sciences, Engineering, and Medicine chronicle the presentations and discussions at a workshop, symposium, or other event convened by the National Academies. The statements and opinions contained in proceedings are those of the participants and are not endorsed by other participants, the planning committee, or the National Academies.

Preface
Commercial aviation in the United States and most other regions of the world is the safest mode of transportation. This high-level safety is the result of many factors, including decades of investments by industry and government and the dedication of researchers, engineers, pilots, air traffic controllers, and a great many other members of the aviation community.
The U.S. national airspace system (NAS) is constantly evolving to take advantage of new technologies, to accommodate growth in the volume of air traffic, to integrate new types of aircraft, to increase efficiency, and to maintain or increase safety. NASA’s Aeronautics Research Mission Directorate (ARMD) conducts research related to several of these topics, including aviation safety. For example, ARMD is conducting research to support development of a real-time safety assurance system for the NAS. Such a system would operate in real time or near real time to monitor the state of the NAS, identify unsafe risks as they arise, and then assist in mitigating those risks. Research by many organizations other than NASA is relevant to the development of a real-time safety assurance system. Accordingly, ARMD requested that the National Academies of Sciences, Engineering, and Medicine convene a committee to develop a national research agenda that would (1) identify key challenges to the development of a real-time safety assurance system for the NAS and (2) identify high-priority research projects that would overcome those challenges.
The Aeronautics and Space Engineering Board of the National Academies Division on Engineering and Physical Sciences has assembled a committee to carry out the assigned statement of task (see Appendix A). The committee members (see Appendix B) met four times during 2017, three times at the Academies’ facilities in Washington, D.C., and once at the National Academies’ facility in Woods Hole, Massachusetts. As specified in the statement of task, the committee has developed a research agenda consisting of a set of high-priority research projects organized around four key elements of a real-time aviation safety assurance system: concept of operations and risk prioritization, system monitoring, system analytics, and mitigation and implementation. The report’s principal finding summarizes the key challenges, and the principal recommendation summarizes the high-priority research projects (see Chapter 6).

In Memoriam
This report is dedicated to Dr. John C. Knight, an accomplished researcher and educator in the field of safety-critical computer systems, especially in the automotive and aerospace fields. He embraced the opportunity to serve on the Aviation Safety Assurance Committee despite a long-term battle with hypersensitivity pneumonitis, and we have missed his camaraderie and counsel in the completion of this work.
