“…Traffic managers would use moderate delaying procedures to reduce the chances for an aircraft to come across thunderstorms along its flight route. Weber et al 44 proposed the thrusts improving the quality and precision of thunderstorm forecasts, converted the forecasts into estimations of future airspace capacity and developed a robust optimization model based on the estimations. They also discussed the thunderstorm problem in future advanced management concepts.…”

This article discusses the recent developments in modelling and simulations for analyses of airspace structures and traffic flows. The topics discussed are new models/methods proposed by researchers in the world for optimal flight paths/ routes, optimal route structures, sectorization and so on and also new developments in the Association of Southeast Asian Nations region. An Association of Southeast Asian Nations modelling and simulation function has been established, so as to perform analyses of airspace structures and traffic flows throughout the Association of Southeast Asian Nations and produce solutions for capacity and efficiency enhancements. The challenges for such research in the Association of Southeast Asian Nations region are also discussed. This review has helped to identify the research gap. The research on air traffic management in the Association of Southeast Asian Nations region is still lacking. Much more efforts should be made in order to meet the demands of this most dynamic and fast growing aviation market in the world. Research on optimal flight paths/routes, more efficient airspace structures and sectorization is expected to be more intensively conducted especially in the Association of Southeast Asian Nations region.

“…Predicting the impact of weather on sectors first requires a weather forecast. A 2-hour convective weather forecast from the Corridor Integrated Weather System (CIWS) 8 was used in developing this concept. The future impact of weather on sector capacity is quantified as reductions in the sector MAP value at different look-ahead times (LATs).…”

Dealing with uncertainty poses a challenge for traffic flow management (TFM) decision making, for example, when rerouting flights to avoid forecast convective weather. These decisions impose costs and delays on flights, and weather does not always materialize where it was forecast or with the forecasted severity. Deciding on a good strategy to take now when faced with uncertain and probabilistic forecasts is difficult for human decision makers. We have developed the deferability concept as an approach for building TFM decision support systems that make decisions incrementally. Simulation studies show this concept can be an effective way to manage airspace congestion using uncertain traffic and weather forecasts.

“…Airspace constraints relate to the aforementioned reasons (adverse weather, other airspace users, airline operations, and air traffic management) for flight delays, diversions, and cancellations. Capacity that is only dependent on the airspace configuration is regarded as the static capacity, whereas dynamic capacity fluctuates to account for other factors such as weather [2][3][4][5][6][7], especially convective weather [8,9]. The convective weather avoidance model relates the required convective weather information, such as the echo top and vertically integrated liquid (VIL) level, to the weather avoidance field and route blockage concept in order to calculate capacity decreases [3,10,11].…”

China is facing ever-increasing constraints in airspace capacity due to a 9.7% average annual increase rate in air traffic over the past decade. This situation underscores the need for the capability to forecast regional air traffic capacity with the operationally critical lead time for the region as well as the whole airspace of China. The end goal is to improve efficiency while maintaining safety and sustaining the growth in civil aviation. Similar to the United States and Europe, weather accounted for over 50% of all the flight delays in China since 2016 and is the biggest detriment to on-time flight performance. This paper reports results aiming to develop and demonstrate a decision support tool concept that provides objective and quantitative operational thresholds for east China regional airspace capacity reductions in the presence of convective weather impacts. By estimating airspace capacities for selected route segments, waypoints, and sectors, we have demonstrated 1) the effectiveness of the flow constraint index-based approach to quantify the airspace capacity in east China, and 2) the capabilities of the forecasted capacity based on the high-resolution nowcast algorithm and numerical weather prediction model compared to the calculated capacity based on observed weather data. The preliminary results indicated that the airspace capacity estimation using the
