Definition
An air traffic facility operated by the FAA that provides pilot briefings, flight plan filing and processing, in-flight advisory services, search and rescue initiation, weather information, and assistance to lost or distressed aircraft. FSS does not provide air traffic control separation services; it provides advisory and support services to pilots before, during, and after flight.
Plain English
An FAA service that helps pilots with weather briefings, filing flight plans, and getting information while flying. It is a help desk for pilots, not a controller that separates traffic.
Context Anchor
You may contact FSS before a flight by phone or online for a briefing, or during flight by radio for updated information or help.
Why Pilots Care
FSS services supply the weather and planning data required for safe and legal flight, reducing the risk of encountering unexpected conditions.
Intuition Check
FSS does not mean an airport fuel or maintenance station. It also is not the control tower; it is a pilot information and support service.
Example Sentence 1
Before departure, the pilot called FSS to get a standard weather briefing and file a VFR flight plan.
Example Sentence 2
While airborne, the pilot contacted FSS on the published frequency to update the flight plan and request current conditions at the destination.
