Research on a System Architecture Design Focusing on Coordination between Functions in Time Management Operations

To realize trajectory-based operations (TBO), there is a need to share trajectory information comprising 3D positions and times with all stakeholders and manage them in time and space. In Japan, while air traffic flow management has been operated as one of the time-based management methods, the implementation of “metering” will be planned in the future. Metering is an operation to ensure arrival intervals through efficient operational methods such as reducing cruising speed. Rather than individual systems and functions working in isolation, there is a need to design the functions of the metering so that the whole system works holistically to achieve benefit.

This study focuses on a system architecture, which represents the relationships among systems. Individual systems and their interconnections are examined to design the system architecture for efficient time-based management operations throughout all flight phases.

The analysis of the overall architecture also takes into account the improvements in arrival sequencing and arrival runway determination implemented in current air traffic flow management systems and calculates the relevant ATM key performance indicators.
