NextGen Trajectory-Based Integration of Grid-Based Weather Avoidance Fields

In anticipation of NextGen requirements for probing of aircraft to weather conflicts within automation systems such as En Route Automation (ERAM), Time-Based Flow Management (TBFM), Common Automated Radar Terminal System (CARTS), and Advanced Technologies & Oceanic Procedures (ATOP), we have been investigating trajectory based methods to integrate gridded weather avoidance fields such as may be available from the 4-dimensional (4-D) weather data cube/Single Authoritative Source (SAS) across multiple ATC domains. The components of our work include 1) Generation of 4-D prototype weather avoidance fields, 2) Retrieval of net-enabled weather data based on Corridor Integrated Weather System (CIWS) derived products using a System Wide Information Management (SWIM) service, 3) Development of a conflict detection service between a hazardous weather data grid and aircraft trajectories, and 4) Visualization of the interaction of weather products, the resulting weather avoidance field and aircraft trajectories. This paper describes the results of the generation, integration and visualization of 4-D trajectories with grid-based hazardous weather avoidance fields.
