THE NATIONAL ACADEMIES
Advisers to the Nation on Science, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. C. D. Mote, Jr., is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Victor J. Dzau is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. C. D. Mote, Jr., are chair and vice chair, respectively, of the National Research Council.

Preface
Technological advances in computer systems, sensors, precision position and navigation information, and other areas are facilitating the development and operation of increasingly autonomous (IA) systems and vehicles for a wide variety of applications on the ground, in space, at sea, and in the air. IA systems have the potential to improve safety and reliability, reduce costs, and enable new missions. However, deploying IA systems is not without risk. In particular, failure to implement IA systems in a careful and deliberate manner could potentially reduce safety and/or reliability and increase life-cycle costs. These factors are especially critical to civil aviation given the very high standards for safety and reliability and the risk to public safety that occurs whenever the performance of new civil aviation technologies or systems falls short of expectations.
Research and technology development plays a critical role in determining the effectiveness of IA systems and the pace at which they advance. In addition, a wide variety of organizations possess key expertise and are making advances in technologies directly related to the advancement of IA systems for civil aviation. Accordingly, NASA’s Aeronautics Research Mission Directorate requested that the NRC convene a committee to develop a national research agenda for autonomy in civil aviation. In response, the Aeronautics and Space Engineering Board of the Division on Engineering and Physical Sciences, with the assistance of the Board on Human–Systems Integration of the Division of Behavioral and Social Sciences and Education, assembled a committee to carry out the assigned statement of task. As specified in that statement, the committee developed a research agenda consisting of a prioritized set of research projects that, if completed by NASA and other interested parties, would enable concepts of operation for the National Airspace System whereby ground systems and aircraft with various autonomous capabilities would be able to operate in harmony; demonstrate IA capabilities for crewed and unmanned aircraft; predict the system-level effects of incorporating IA systems and aircraft in the National Airspace System; and define approaches for verification, validation, and certification of IA systems. The committee was also tasked with describing contributions that advances in autonomy could make to civil aviation and the technical and policy barriers that must be overcome to fully and effectively implement IA systems in civil aviation.
Unlike typical NRC reports, this report often cites news media (magazines, newspapers, and online blogs) as the source of information contained in the report. In all cases, these sources are used to report recent events in the fast-changing world of IA systems and unmanned aircraft. They are not used as the basis for any scientific or technical analysis or conclusions.
The staff of the Board on Human-Systems Integration assisted the staff of the Aeronautics and Space Engineering Board in developing the statement of task for this study and in forming the 17-member committee. The
committee met five times during 2013 and 2014: three times in Washington, D.C., and twice in Irvine, California. At these meetings the committee was informed by presentations and materials provided by current and former personnel from the Federal Aviation Administration, NASA, the National Highway Traffic Safety Administration, the U.S. Air Force, the U.S. Army, the U.S. Navy, academia, industry, and independent research institutes.
