Abstract
We provide a concept of operations and a corresponding implementation of a long-range air traffic flow management in the Asia-Pacific region. This management will provide an appropriate demand-capacity balancing considering both aircraft sequencing by local arrival management procedures and flow optimization to prevent over-demand in the approach area around the airport. Thus, coordination of long-range international flights demands collaboration between different flight information regions and local regulations. As Singapore Changi Airport is a central element of the Asia-Pacific flow management high share of long-haul air traffic, we use this airport to demonstrate our approach. To derive the operational conditions and actual traffic patterns at the airport, ADS-B messages and flight plan information are processed. The data are cleaned, analyzed, and filtered to provide information about arrival flows within given distances to the airport. We provide an efficacy analysis of the long-range air traffic flow management using two approaches. First, we applied a mixed-integer optimization of time shifts of normal distributed flight times. Here, the regulation of long-range flights by time shifts (e.g., achieved by speed advisories) shows a significant relief from periods of over-demand at the airport approach sector. Second, we implement a reference and a test case scenario in an agent-based simulation environment including the local arrival management procedures. Here, the number of holdings and the associated holding time could be reduced by at least 26%.
Highlights
The air transportation system provides infrastructures and procedures to ensure the efficient utilization of given resources, such as airspace or airport capacity
Since Air Traffic Flow Management (ATFM) has already been shown to contribute to flight efficiency, cost-effectiveness, and environmental sustainability of the air transportation system, we demonstrate the substantial improvements associated with the Long-Range Air Traffic Management (LR-ATFM) approach
LONG-RANGE AIR TRAFFIC FLOW MANAGEMENT LR-ATFM is an additional part of flight regulation during an active flight and provides a link between en-route flight operations, regional ATFM regulations along the flight path, and local arrival management
Summary
The air transportation system provides infrastructures and procedures to ensure the efficient utilization of given resources, such as airspace or airport capacity. FOCUS AND STRUCTURE OF DOCUMENT In our paper, we develop for the first time a mathematical model for the LR-ATFM approach and implement it in a simulation environment with operational constraints From this tactical traffic flow management concept, regulation solutions for the long-haul air traffic are derived while optimizing the airport capacity utilization. The control of air traffic by network interventions can lead to congestion at specific nodes, in particular when (increased) AMAN activities are not taken into consideration [71] This can be avoided with an integrated and balanced consideration of both local arrival and flow management, aiming at a cost reduction by moving delay into a more efficient phase of flight. Flight tests have shown that advice should only be given if the recommended speed significantly deviates from the current speed, e.g., only for changes greater than 0.01 Mach [79]
