The NextGen Weather Program is a critical part of NextGen as it helps reduce the impact of weather on aviation, resulting in safer, more efficient and predictable day-to-day National Airspace System (NAS) operations.

NextGen Weather harnesses massive computing power, unprecedented advances in numerical weather forecasting, translation of weather information into airspace constraints, and modernized information management services. With this powerful combination, NextGen Weather can provide tailored aviation weather products within the NAS, helping controllers and operators develop reliable flight plans, make better decisions, and improve on-time performance.

The flying public will experience less weather delay, including fewer departure and arrival delays, reduced number of flight cancellations and refueling stops, and overall increased dependability in flight schedules.

NextGen Weather is accomplished through collaboration between FAA, NOAA, and NASA.

NextGen Weather Components

The fully-automated NextGen Weather Processor (NWP) identifies terminal and enroute safety hazards, and provides support for strategic traffic flow management, including the translated weather information needed to predict route blockage and airspace capacity constraints up to eight hours in advance.

The NWP Aviation Weather Display (AWD) consolidates current weather displays and provides consistent weather information “at a glance” for enroute and terminal users.

Common Support Services (CSS-Wx) modernizes information management services for weather, and provides tailored weather products within the NAS via System Wide Information Management (SWIM).

The connectivity between these components and their relationship within the NAS are shown in the high-level overview of NextGen Weather Architecture.
