“…For each 4D-trajectory point (φ, λ, h, t), placed in the appropriate cell depending on its coordinates, the separation between this point and all the points in the same and neighbor cells is verified, and if violated, then a point-to-point conflict is detected (see [38] for more details), and the total number of point-to-point conflicts, C t , is increased. Figure 12 demonstrates the potential conflicts detected for a set of WOFR for 546 eastbound transatlantic flights on July 15 th 2012, where the conflict points are marked in red.…”

“…However, as demonstrated in [20], delaying flights is not enough for conflict resolution, thus, trajectory shape modification is applied. To modify the geometrical shape of a trajectory, we exploit a bijective transformation between an arbitrary curve on a sphere and a curve on the xy-plane, as demonstrated in Figure 13 (see [38], [21] for more details). The bijective function curvature The physical constraints of the problem are the separation norms between the 4D trajectory points, which has been relaxed in the objective function as in the previous section III-E. As a result, the only constraints of our formulation are the boundary constraints on the decision variables, and the objective function is designed to minimize the total number of point-to-point conflicts, C t (z), induced by the set of modified trajectories corresponding to the variables z.…”

The North Atlantic oceanic airspace is considered the most congested oceanic airspace in the world. For many years, air traffic control in this airspace has experienced difficulties due to the limited radar coverage. To support conflictfree flight progress, a structure of routes, called Organized Track System, is established in the North Atlantic airspace and very restrictive separation standards are applied. The development of the Automated Dependent Surveillance-Broadcast system provides an opportunity to improve the flight planning operations over the oceans by reducing separation norms. The aim of this study is to improve the traffic efficiency in the North Atlantic airspace by developing new approaches to organize the transatlantic traffic at the strategic level. The first considered approach proposes a new route structure, referred to as Wind-Optimal Track Network, to replace the Organized Track System, while the second one is based on Wind-Optimal Free Routes. The problem is modeled as an optimization problem and resolved further via Simulated Annealing combined with Sliding Window algorithm. Results of simulations performed on the real traffic data prove that about 76% of flights decreased their cruising times by more than half an hour when flying wind-optimal tracks rather than using their great circle routes from the departure to the destination. Furthermore, by comparing the two proposed methods we conclude that Wind-Optimal Free Routes implies lower cruising times, while the Wind-Optimal Track Network is much more robust under changing wind fields.

North Atlantic oceanic airspace accommodates air traffic between North America and Europe. Radar-based surveillance is not applicable in this vast and highly congested airspace. For conflict-free flight progress, the Organized Track System is established in North Atlantic, and flights are prescribed to follow pre-defined oceanic tracks. Rerouting of aircraft from one track to another is very rarely applied because of large separation standards. As a result, aircraft often follow routes that are not optimal in view of their departure and destination points. This leads to an increase in aircraft cruising time and congestion level in continental airspace at input and output. Implementing new technologies and airborne-based control procedures will enable significant decrease in the present separation standards and improvement of the traffic situation in North Atlantic.The aim of the present study is to show the benefits that can be expected from such a reduction of separation standards. Optimal conflict-free trajectories are constructed for several flight sets based on the new proposed separation standards, with respect to the flight input data and oceanic winds. This paper introduces a mathematical model; it proposes an optimization formulation of the problem; it constructs two test problems based on real air-traffic data, and it presents very encouraging results of simulations for these data. * Manuscript received ; revised † The authors are with ENAC,

Aeronautical Ad-hoc NETworks (AANETs) have been studied and could be proposed as an complementary communication system for civil aviation. Several routing algorithm have been proposed and assessed through simulation, but there is a lack of evaluation in realistic conditions, especially regarding the access layer. In this paper we propose to use Random Packet CDMA (RP-CDMA) as a MAC layer protocol for AANETs. We then present the results of simulations with actual aircraft trajectories considering successively three well-known routing algorithm (namely AODV, DYMO and BATMAN). We conclude from these simulations that AODV has the best performances, but also that the realistic access layer is quickly saturated by the mere signalization traffic. This calls for improvements in both routing algorithms and access layer.
