Definition
The computer system used by Flight Service Stations (FSS) to deliver preflight weather briefings, accept and process flight plans, distribute Notices to Air Missions (NOTAMs), and provide other inflight services to pilots. It links FSS specialists to national weather, NOTAM, and flight plan databases so they can pass current information to pilots over the phone, radio, or through online services.
Plain English
It is the computer setup that Flight Service uses to give pilots weather briefings, take their flight plans, and pass on safety notices.
Context Anchor
Seen in FAA acronym lists and in material about Flight Service, preflight briefings, flight plans, and pilot information services.
Why Pilots Care
It gives pilots faster, self-service access to flight planning and weather tools without always needing a live briefer.
Intuition Check
Do not read FSAS as an onboard aircraft system. In this context, it refers to a Flight Service computer system used to support pilot information services.
Example Sentence 1
When the briefer pulled up the latest weather and NOTAMs for our route, that information was coming through the FSAS.
Example Sentence 2
Updated weather data is available to pilots directly from FSAS at any time of day.
