JPDO Progress Article #2: Weather
June 17, 2009
Roughly 70 percent of all delays in the national air transportation system are attributed to weather. The Congressional Joint Economic Committee estimates that weather-related air traffic delays cost the U.S. economy $28 billion a year. Most notably, however, it is estimated that up to two thirds of these delays can be avoided. That is why the JPDO, in conjunction with its government partners, has been working to develop an overarching concept of operations and a strategy for transforming the way weather information is managed and applied within the National Airspace System (NAS). The goal is simple: significantly reduce air traffic delays caused by weather.

Through its Weather Working Group, the JPDO is developing the concept of the Four-Dimensional (4-D) Weather Cube. The 4-D Weather Cube will offer all users of the national air transportation system (e.g., controllers and pilots), at all levels, the capability to display and utilize a common weather picture in their respective decision-making processes. This capability will rely on a virtual database that serves as a single authoritative source for government-based activities. A document entitled, “Four-Dimensional Weather Functional Requirements for NextGen Air Traffic Management”, which contains more details on the 4-D Weather Cube, was released in January 2008, and is currently available here, on the JPDO Web site.
