Research on the Impact of TBO on Airline Planning and Scheduling

The "Aviation System Block Upgrade Plan(ASBU)" proposed by the International Civil Aviation Organization has made Trajectory-Based Operations (TBO) a key project in the field of efficient flight trajectory performance improvement, and countries have successively proposed their own next generation air traffic management(ATM) strategies for developing TBO. However, the study on the new air transportation system of various countries rarely analyzes the impact of TBO on airline operation control. First, this article analyzes the basic concepts and development of TBO and airline planning and scheduling. Then, from the four perspectives of interval management, operational optimization, air-ground communications, and flight operations monitoring, it focuses on the analysis of the specific impact and new opportunities that TBO operations will have on airline planning and scheduling. Finally, it is concluded that in response to the above-mentioned impacts and new opportunities, airlines can adopt new technologies such as blockchain and artificial intelligence to cope with these changes in airline operational control, so as to improve their operational optimization capabilities and safety levels.
