“…The flight plan constitutes a velocity V II ∈ [V min , V max ] and a path deviation h ∈ [0, h max ] from the straight line path between WP1/WP2 and WP3. As in [2] and [14], changing V II and h modifies the arrival time at WP3, which we will use to space merging aircraft. This is illustrated in Figure 2.…”

“…safe merging is guaranteed at the merge points [14]. In Point Merge, another centralized merging and spacing solution, aircraft approaching the terminal area achieve the desired separation by flying on one of the vertically spaced sequencing legs [2]. National Aeronautics and Space Administration (NASA) is also actively involved in air traffic management research [1].…”

FAA's NextGen program aims at increasing the capacity of the national airspace, while ensuring the safety of aircraft. This paper provides a distributed merging and spacing algorithm that maximizes the throughput at the terminal phase of flight using the information provided through the ADS-B framework. Using dual decomposition, aircraft negotiate with each other and reach an agreement on optimal merging times, with respect to an associated cost, that ensures proper inter-aircraft spacing. We provide a feasibility analysis that gives sufficient conditions to guarantee that proper spacing is achievable and derive maximum throughput controllers based on the air traffic characteristics of the merging flight paths.

“…Instead of using heading vector, PM only uses speed control and "direct to" instruction to guide the aircraft to merging point, and it has two clear steps to execute them one by one. Its special route structure and procedures provides a potential approach to realize an automated separation assurance to the arrival flow under high traffic load situation [13].…”

This paper presents a new approach for automated merging multiple aircraft flows in a busy Terminal Maneuvering Area (TMA). This work is motivated by the current overloaded airspace in the Beijing Capital international airport, the highlighted delay in the China air transportation and the need of more efficient methods to help air traffic controllers.Present research consists of a new approach to optimize a set of aircraft planned to land at a given airport based on multiagents technique, which is automated generating comprehensive sequencing plan and conflicts-free trajectories. The architecture of the system is based on a Point Merge (PM) route structure to enable expediting or delaying aircraft while staying on lateral navigation mode. The whole system is designed by two main models to manage the process of arriving flows: Sequencing leg and Link. And then, 4 kinds of agents are designed to support the implementation of this automated system: aircraft agent, flow manager agent, conflict detection and resolution agent and 4D trajectory planning agent. We consider the 4D trajectory-based operation situation in TMA and apply different wake turbulence constraint in these two models. Finally, a conclusion is made and future work is outlined.

“…The point merge concept [11][12][13] is different from those mentioned above in that it is not timebased. RNAV routes leading to merge points end with isometric segments tangential to the merge point.…”

This paper introduces the concept of using tactical shortcuts to improve arrival precision and thereby increase throughput. This concept schedules flights to a longer path for which a shortcut path option is available for time recovery when speed is restricted. Shortcut design parameter sensitivity for schedule-based and spacing-based use policies is explored for single vs. multiple shortcut designs and shortcut availability. Simulation results show schedule-based shortcuts can reduce scheduling buffer size by 35-55% (increasing maximum throughput) or reduce separation violation probability 15-20% (reducing controller workload). Spacingbased shortcuts can reduce scheduling buffer size or separation violation probability by an additional 20% or 5% respectively. Additional studies were conducted to evaluate throughput and delay performance of each shortcut use policy for a wide range of demand rates. Spacing-based shortcuts performed the best. A use policy that combined the schedule-based shortcut method and scheduling without shortcuts outperformed using either of these methods individually. The potential benefits of using tactical shortcuts warrants future study in its application to multi-point scheduling, performancebased operations, geometric design, and decision support tools.
