Trajectory Management Under Operational Constraints Caused by Significant Weather Conditions

To ensure cooperative trajectory management prior to departure, all stakeholders must make decisions based on a high-level common understanding of aviation weather, aircraft operation and air traffic management. Accordingly, research and development on selecting a preferred flight route is expected and suitable flow control and capacity settings must be conducted with knowledge of an advanced weather forecast.

This study aims to enhance flight operations, air traffic flow management and airspace capacity management by visualizing and quantifying the effects of significant weather conditions on these operations, ultimately enhancing cooperative decision-making prior to departure. In particular, significant weather avoidance is modeled and airspace capacity limitations under significant weather conditions are derived. A system for visualizing and displaying significant weather conditions, aircraft trajectories and airspace capacity is also developed.

Visualization of inclement weather, aircraft trajectories, and airspace capacity. In case of bad weather, the aircraft is flying a modified trajectory instead of a standard route.
