Long-term Vision


Research and Development Long-Term Vision
June 2019

– Study Committee for Research and Development Long-Term Vision –

 ENRI is a central research institute for the air traffic systems in Japan. One of ENRI’s prime tasks is to improve the quality of life by through the development of science and technology by understanding issues related to air traffic systems. Active participation in standardization activities is also considered as a high priority for setting the technical standards that ensure global interoperability.

 The 6th edition of Global Air Navigation Plan (GANP) is being set at the International Civil Aviation Organization (ICAO), and the 13th Air Navigation Conference (AN-Conf/13) was held in October 2018 ahead of the 40th ICAO General Assembly. Research and development of unmanned aircraft systems and supersonic aircraft are being actively carried out both in Japan and overseas, and technological innovation is expected to advance in these fields in the future. As the demand for world aviation rapidly changes, ENRI revised its Research and Development Long-Term Vision in June 2019, creating a long-term vision for research for the new era.

 In a future air transportation system, in addition to conventional aircraft, various aerial vehicles with different performance characteristics and purposes are expected to operate, requiring flexible airspace management that can accommodate this greater diversity. For example, a mixed-equipage environment consists of large unmanned aircraft systems, supersonic aircraft, sub-orbital vehicles at high altitudes, small unmanned aerial vehicles and urban air mobility vehicles at low altitudes is anticipated in such a system. Furthermore, air traffic management will become highly advanced where the concept of Trajectory Based Operations (TBO) would become a reality. TBO considers the interference between aircraft and operational efficiency to determine and adjust the flight trajectory of an aircraft in advance, which then operates on that trajectory in a predetermined time. Hence, TBO requires the introduction of various measures.

 The Research and Development Long-Term Vision is broadly categorized into four categories: effective use of airspace by improving operational safety and reliability; increasing the efficiency of airspace operations; improving the efficiency of airport operations; and developing fundamental technologies for the advancement of air traffic control systems. Major constituent technologies for which research and development ought to be promoted are summarized in the ENRI Research and Development Long-Term Vision Roadmap (see Appendix).

 This revision was carried out with reference to the progress of CARATS, the ICAO GANP issued in September 2016, and the discussions of the AN-Conf/13 in October 2018. The actual research plans at ENRI will be dynamic and flexible, considering changes in the situation surrounding air traffic control systems, while referring to this Long-Term Vision. To promote research activities effectively, ENRI is determined to collaborate with industries, academia, and government to carry out research activities in the field of air traffic systems. ENRI believes that expanding and strengthening collaboration, including collaborative research carried out with universities and research institutions, will yield maximum research results.
