The Small Aircraft Transportation System (SATS) program has been established by the Office of Aerospace Technology in the National Aeronautics and Space Administration (NASA). In the initial 5-year phase of the program, NASA is working with the private sector and university researchers, as well as other federal and state governmental agencies, to further various aircraft-based technologies that will increase the safety and utility of operations at small airports, allow more dependable use of small airports, and improve the ability of single-piloted aircraft to operate safely in complex airspace. Guiding this program is a longer-range SATS vision of the routine use of advanced, small fixed-wing aircraft for personal transportation between communities. NASA asked the Transportation Research Board (TRB) to convene a study committee to review the plausibility and desirability of the SATS concept, giving special consideration to whether its potential net benefits--from user benefits to overall environmental and safety effects--are sufficiently promising to warrant public-sector investment in SATS development and deployment. The TRB committee's findings are presented in this special report. The committee does not share NASA's vision for SATS, nor does the committee support the use of this vision to guide technology development and deployment investments. Nevertheless, the committee endorses NASA's efforts to develop and demonstrate technologies that can help further the highly desirable outcomes stated above. To help achieve these outcomes, the committee urges NASA to prioritize, without regard to the SATS concept, the capabilities and technologies now being pursued in the 5-year program according to a clearly delineated set of civil aviation needs (such as improved general aviation safety) that these new capabilities and technologies can help meet. The report is organized in five chapters: (1) Study Overview and Aims; (2) U.S. Civil Aviation Fleet, Airport, and Airway Use Characteristics; (3) Air Transportation Challenges: Enhancing Capacity, Service, Safety, and Environmental Compatibility; (4) Analysis of Small Aircraft Transportation System Concept; and (5) Summary Assessment and Advice. An executive summary is provided and at the end of the report there is an afterword on SATS and aviation security. |
