“…5 sub-routes are attached to this original route as illustrated by dashed lines. For instance, one of these sub-routes consisted of Link 8,13,14,15,16,17,18,6,and 7. This topology design has one main merging point (Node 4), 3 original routes with 5, 8 and 4 subroutes, making a total of 16 sub-routes.…”

The current overloaded airspace near large airports leads the stakeholders to develop more fundamental means to improve the use of available air capacity in dense traffic areas as terminal maneuvering area. A smart planning of aircraft trajectories and an appropriate designing of route structure can be a solution. Therefore, to analyze the capability of them, this paper proposes a novel approach to deal with the merging and sequencing problem of arrival traffic in terminal maneuvering area, and examines the performance of diverse conflict resolution strategies and different terminal maneuvering area route structure. An evolutionary algorithm is employed to resolve potential conflicts, altering one or more of the following decision variables: routes, speeds, and entrance time to terminal maneuvering area (slot). Two different fitness functions were developed. One aims to minimize potential conflicts and the other one aims to minimize at the same time potential conflicts and delay induced at runway. The performance of different combinations of decision variables, or conflict resolution strategies, is evaluated through a set of arrival aircraft to Grand Canaria airport. Also, four different route structures are tested by using the same set of incoming aircraft. The results showed that the slot and speed change and mix of all change strategies can successfully resolve all conflicts in an efficient manner. The results also suggested that topologies with one main merging point are more efficient than the ones that have two merging points. Finally, a significant abatement of delay was observed when minimizing conflicts and delay while achieving conflict-free solutions.

“…In [4] a broader suite of concepts have being investigated to address merging and spacing problems arising from structured RNAV and Required Navigation Performance (RNP) routes in the terminal environment referred to as Spacing of Performance-based Arrivals on Converging Routes (SPACR). It addresses the nearterm merging and spacing problem.…”

“…Depending on the route used, aircraft may have more or less options for the path planning. For instance (see Figure 3), an aircraft entering entry point 1 has alternative choices only on link (1, 5) but an aircraft entering entry point 2 has alternative choices on links (2, 4) and (4,5). So our state space X may be summarized by the following table :…”

This paper presents a new approach for merging multiple aircraft flows in a Terminal Maneuvering Area (TMA). This work is motivated by the current overloaded airspace near large airports and the need of more efficient methods to help controllers. Some attempts to alleviate airspace congestion such as the minimum spacing requirements, negotiation of voluntary reductions in scheduled service, and the construction of additional runways at major airports have been done. Even though, more fundamental changes are needed to improve the use of available air capacity. Present research consists of a new approach to optimize a set of aircraft planned to land at a given airport; it is proposed to merge the incoming flows from different routes by mean of speed and path changes. Due to the high combinatoric induced by such a problem, a stochastic optimization algorithm has been developed in order to propose to each aircraft a new route and speed profile. Those changes aim to remove conflicts at merging points and to maintain separation of aircraft following the same route link according to their wake turbulence constraint. The optimization criteria is based on the minimum deviation from the initial path planning. This algorithm has been successfully applied to Gran Canaria airport in Spain with real traffic demand samples for which conflict free flow merging is produced smoothly with optimal runway feeding.

“…However, in practice there are uncertainties and noise (such as wind) which affect both the prediction and execution of arrival trajectories. Inaccuracy of the actually realized TBM delivery times from the ideally scheduled times will be inevitable, and terminal controllers will sometimes need to vector aircraft off their RNAV STAR procedures in order to maintain separations [4].…”

The NextGen Integration and Implementation Office of the Federal Aviation Administration has outlined a set of novel operational concepts for improving the efficiency of air traffic operations. In the terminal domain, one proposed operational change is Time-Based Metering (TBM) utilizing Area Navigation (RNAV) Standard Terminal Arrival (STAR) route assignments. The MITRE Corporation's Center for Advanced Aviation System Development (CAASD) was tasked to provide benefits and feasibility analysis of these proposed changes and to develop models to test concepts for use in the management and control of air traffic. This paper describes the evaluation of potential benefits and constraints on the feasibility of implementing TBM along RNAV STAR routes. It focuses on computer simulated trial runs of a case study in which time-based metered delivery is implemented at Hartsfield-Jackson Atlanta International airport. This study has yielded two important findings. The first finding is the maximum tolerable variation of actually realized en-route to terminal delivery times from the prescribed schedule times. The second finding is an estimate of the potential reduction in low altitude vectoring in high density airspace.
