| Outline of Final Research Achievements |
In the future air traffic management, the concept of flow corridors - long, narrow airspaces connecting metropolitan areas or airports with high air traffic demand - is envisioned. Aircraft with the ability of maintaining autonomous spacing will be able to fly within the corridor on an optimal trajectory without the need for the air traffic control, which is expected to significantly increase their benefits. On the other hand, other aircraft must fly while avoiding the flow corridor airspaces, which will increase operating costs. In this study, through the analysis of actual flight data, the required penetration rate of maintaining autonomous spacing was clarified as a requirement for the introduction of flow corridors into Japan to bring benefits. Furthermore, evaluation of the accuracy of four-dimensional trajectory, which is a key element to realize the flow corridor, and modeling of the flow corridor as a function of weather conditions were carried out.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により、自律間隔維持の機能を大型機に優先的に導入することにより、その普及率が低い段階においても我が国の空域へのフローコリドーの導入が便益をもたらすことが明らかとなった。また、自律間隔維持の機能を持つ機体ほど大きな便益を得ることになるため、フローコリドーの導入が自律間隔維持の機能の普及を促進することも明らかとなった。また、その実現の要となる四次元軌道の精度を評価し、気象条件によるモデル化の手法を明らかにした。このモデルの活用により、気象条件に寄らず常にフローコリドーを安全かつ効率的に運航できるようになる。また、このモデルは今後の航空交通管理において広く活用できるものと期待される。
