efficient management of arrival flows

1 February 2025

Efficient management of arrival flows is a key aspect of air traffic management, particularly for long-haul flights. In the Asia-Pacific region, the coordination between multiple air navigation service providers presents a significant challenge, requiring precise synchronization of arriving flights. Initial analyses of Long-Range Air Traffic Flow Management (LR-ATFM) have already been conducted for Singapore Changi Airport. These analyses are now to be expanded to include a broader assessment of traffic flows from different regions.

This study aims to analyze flight schedules and operational data from March to December 2019 to identify key parameters such as operational directions, weather influences, and comparable traffic days. Subsequently, arrival flows will be assigned to their respective Flight Information Regions (FIRs), and clustering techniques will be applied to examine flight routes within these flows. Based on these findings, demand for airport capacity will be derived depending on the remaining flight time. Finally, a concept for flow-oriented arrival management will be developed, with a particular focus on traffic streams from Japan and Australia. The results will be evaluated for their potential to improve arrival flow efficiency through time-based control and formulated as requirements for a future optimized arrival management system.
