“…In this Section, we describe a method devoted to organizing the traffic in the NAT based on windoptimal free routes (WOFR), which may become operationally acceptable thanks to more precise surveillance, reduction of the separation norms, and more efficient aircraft separation (including airborne self-separation) [32,33]. The first step of the proposed method involves creating new aircraft routes for each single flight separately, taking into account aircraft performance metrics and environmental conditions.…”

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.

Remote-controlled or autonomous multi-rotor air vehicles, or drones, have become common and commercially available even to individual consumers, mostly for imaging purposes. Drones appeal to mission architects looking to extend the toolbox provided to operators performing challenging missions such as public safety operations. However, careful analysis of the operational context and concept of operations must take place before major acquisitions. The purpose of this paper is to propose a model-based operational architecture definition framework, which is based on the Department of Defense Architecture Framework (DoDAF) ontology and uses Object Process Methodology (OPM) as its underlying modeling language. Through careful mapping of DoDAF Operational Viewpoint (OV) ontology to OPM ontology, we were able to show that the entire OV ontology can be covered by a small set of objects, processes, relations among them, and constructs comprising them. We then show how to instantiate the ontology to create a model of an actual architecture of interest (AoI) while maintaining strong typing of the model elements to ensure validity, integrity, consistency, and continuous compliance with the OV. We demonstrate our approach on the case of using drones in public safety enterprises for the purpose of crowd management in massively attended events and locations. The proposed framework allows for capturing ConOps and OpsCon in a lightweight, yet robust and consistent manner, and improve communication and concept validation between operational stakeholders and enterprise architects.

“…Eastbound flights prefer to follow the jet stream in order to benefit from strong tailwinds, while westbound flights would make efforts to avoid the jet stream [4]. Development of new generation surveillance and broadcast technologies [7], supported by ATM modernization projects, will allow each individual aircraft to plan and execute its trajectory with less restrictions [8]. Thus, each aircraft will be better able to take advantage of environmental conditions (weather, traffic, etc.)…”

“…On the other hand, when the time intervals overlap just at the borders, one could consider that this conflict would rarely occur in reality. In this case, by summing up such conflict probabilities over all neighbor pairs of trajectory point, an objective function to be minimized by the algorithm, C t , is obtained (8):…”

Air traffic in the North Atlantic oceanic airspace (NAT) experiences very strong winds caused by jet streams. Flying wind-optimal trajectories increases individual flight efficiency, which is advantageous when operating in the NAT. However, as the NAT is highly congested during peak hours, a large number of potential conflicts between flights are detected for the sets of wind-optimal trajectories. Conflict resolution performed at the strategic level of flight planning can significantly reduce the airspace congestion. However, being completed far in advance, strategic planning can only use predicted environmental conditions that may significantly differ from the real conditions experienced further by aircraft. The forecast uncertainties result in uncertainties in conflict prediction, and thus, conflict resolution becomes less efficient. This work considers wind uncertainties in order to improve the robustness of conflict resolution in the NAT. First, the influence of wind uncertainties on conflict prediction is investigated. Then, conflict resolution methods accounting for wind uncertainties are proposed.
