Flight Service

Mission

  • Provide world class service and value to users of the National Airspace System (NAS), including mixed aviation
  • Leverage advanced technologies to safely and efficiently deliver flight services in the contiguous United States (CONUS), Hawaii, Puerto Rico, and Alaska
  • Support the ATO's System Operations Services with innovative, collaborative solutions to complex operational problems

What We Do

Flight Service provides pilots with weather and aeronautical information through pilot briefings, flight planning, inflight advisory services, weather cameras, search and rescue initiation, aircraft emergencies, and Notices to Airmen (NOTAMs). Flight Service delivers services in Alaska by government personnel and in the continental U.S. (CONUS), Hawaii, and Puerto Rico with a contract service provider (Leidos). Flight Service manages the vendor contracts, costs, and customer satisfaction within the NAS. The Flight Service Pilot Web Portal 1800wxbrief.com allows pilots to receive online preflight briefings, file flight plans and get automatic notifications and alerts, including flight plan closure reminders for CONUS, Hawaii, and Puerto Rico. Registering for automatic notifications keeps pilots informed when new or adverse conditions arise, such as a severe weather forecast or observation, an airport closure, NOTAM or temporary flight restriction.

The United States NOTAM Office (USNOF) provides oversight on domestic and international NOTAM transactions and is the final authority on NOTAM formatting. Embedded within the Air Traffic Control System Command Center in Warrenton, VA, USNOF specialists work alongside the Joint Air Traffic Operations Command (JATOC) to deliver real-time National Airspace System (NAS) data regarding high-visibility events.

Flight Service encourages innovation in the delivery of services to pilots. In support of continuous improvement and to increase efficiencies for our stakeholders, we plan to:

  • Expand automation capabilities and enhance delivery methods for future operations in Alaska and CONUS, Hawaii, Puerto Rico
  • Explore ways to interpret and disseminate weather information with future technologies

Additional Information

The FAA published a Federal Register Notice in 2025 notifying the public of its intent to decommission the entire RCO network in the CONUS. After numerous public comments and the results of a Safety Panel, the FAA revised its approach and will retain 262 RCOs until technology allows for further reductions.  Remote communications outlets in 674 locations will be decommissioned beginning in late fiscal year 2026. Notices to Airmen (NOTAMs) will be issued as each frequency is decommissioned. Frequencies in Alaska and those designated for emergency or military use are not included.
