Associate Professor Masaki Inoue of the Faculty of Science and Technology at Keio University, along with Minami Ishii (a second-year master's student) and Shinji Wada (a master's student at the time of the research) from the university's Graduate School of Science and Technology, have developed a new traffic management method called Semi-Continuous Descent Operation (Semi-CDO) by addressing the issue of aircraft arrival management in air traffic management.
In recent years, there has been growing interest in environmental issues on a wide scale, from the global to the local living environment, and efforts to solve these problems are also expected in the aviation sector. To achieve this, it is not enough to simply advance individual aircraft; it is also essential to improve the efficiency of air traffic management, which controls groups of aircraft.
In this study, we discovered that with conventional Continuous Descent Operations (CDO), arrival times can be indirectly controlled by making altitude adjustments during descent. Based on this, we developed Semi-CDO, a traffic management method that incorporates a mathematical model-based altitude adjustment algorithm into CDO.
This research was conducted in collaboration with Principal Investigator Daichi Toratani of the Electronic Navigation Research Institute, National Institute of Maritime, Port and Aviation Technology.
The results of this research were published online in an early access version in the international journal "Journal of Aircraft" from the American Institute of Aeronautics and Astronautics (AIAA) on September 6, 2023 (JST).
