For the Next Generation Air Transportation System (NGATS), we present trajectory design guidelines focusing on dynamic weather avoidance routing in transition airspaces -within 200 nmi of an airport or a set of metroplex airports. Assuming a Net-Centric Operation (NCO) that provides a mechanism to inform all users of hazardous weather constraints and weather avoidance routing requirements, the NGATS can move away from static jet route routing toward a system in which routes are defined dynamically in four dimensions (4D), and adjusted during the course of the day as required by traffic demand and the geometry of severe weather constraints. Such an operational concept will be particularly useful for time periods for which weather is a major constraint to terminal area operations, and when Super-Dense Operations (SDO) are thus required to maintain a high throughput. This paper describes both a Concept of Operations (ConOps) for using 4D trajectories to establish SDO in NGATS and an approach to designing 4D trajectories.

“…The authors of [9] propose a graph based method that relies on application of Dijkstra's along with additional heuristic techniques while attempting to consider aircraft dynamics in the path planning problem. Application of A* searches or Ant Colony searches coupled with other heuristics for rapidly generating optimal routes are found in [10,11].…”

This paper considers the problem of rapidly generating aircraft trajectories and providing visual tools for analyzing airspace in the presence of convective weather. When strong convective weather elements are present within an airspace, nominal operations are disrupted. Often, such disruptions result in the closure of arrival and departure routes, or major jetways. Partial recovery from disturbances can take the form of ground delay programs and diversions, re-routing of flights to adjacent airspaces, or utilization of other standard arrival and departure fixes. The work presented here proposes two decision support tools to aid air traffic controllers and managers in re-routing traffic. Starting from weather information, partitions of the airspace are constructed whose boundaries and junctions form a Voronoi graph. The graph is used for path planning and provides information on optimal routing policies. Furthermore, the partitions are also used to identify the set of reachable space by airplanes. A key feature of the tool is that a set of optimal solutions and/or informational content is provided, as opposed to simply providing a single optimal trajectory solution or output with limited informative content. The sets of optimal solutions are obtained by finding homotopy classes for flight routing, leading to greater flexibility in decision making. The central thesis of this paper is that graph-based and continuous trajectory-based path planning algorithms can provide the necessary information for strategic and tactical path planning through weather, and are thus well suited as decision support tools for enhancing air traffic management.

This paper describes simulations of an automated planning system that routes flights around airspace impacted by forecasted convective weather. If the system predicts that a flight will enter a weather-impacted airspace within a predefined time horizon, it generates a new route. Because the forecasts are uncertain, the system periodically generates, using updates of the weather forecasts and radar tracks, new reroutes. The simulations included convective weather in the northeastern quadrant of the United States over a 24-hr period. Multiple simulations investigated the system performance as the planning horizon and planning frequency varied. As the planning horizon and frequency increased, the system successfully routed more traffic around weather but with more route changes. For a planning horizon of 20 to 120 minutes and a planning frequency of four cycles per hour, the reroutes increased flight time by 3.3% and avoided 79% of the weather-impacted airspaces that were detected. Most flights required one to three reroutes to pass by a weather-impacted airspace, while the worst case flights required six reroutes.
