Support for Strategic Traffic Flow Management

Refer to the following caption
Traffic managers at Air Traffic Control System Command Center have primary responsibility for traffic flow management in the National Airspace System.

NextGen Weather represents the consolidation, modernization, and improvement of FAA weather capabilities. One of the primary new capabilities is the support for strategic traffic flow management. This includes three main thrusts: extending 2 hour predictive weather products out to 8 hours, translating predictive products into predicted constraints on air traffic operations, and providing measures of confidence for predicting operational weather constraints.

Since weather delays are largest in the summer, and predicting thunderstorm development can be so uncertain, NextGen Weather products are specifically designed to support traffic management over 2–8 hour lead times when convective weather is expected. The capabilities described here are enabled by the strong collaboration between NOAA, NASA and the FAA.
