A Flight Service Station (FSS) is an air traffic facility that provides information and services to aircraft pilots before, during, and after flights, but unlike air traffic control (ATC), is not responsible for giving instructions or clearances or providing separation. The people who communicate with pilots from an FSS are referred to as specialists rather than controllers, although in the US, FSS specialists' official job title is "air traffic control specialist – station".
The precise services offered by stations vary by country, but typical FSS services may include providing preflight briefings including weather and notices to airmen (NOTAMs); filing, opening, and closing flight plans; monitoring navigational aids (NAVAIDs); collecting and disseminating pilot reports (PIREPs); offering traffic advisories to aircraft on the ground or in flight; relaying instructions or clearances from air traffic control; and providing assistance in an emergency. In many countries, flight service stations also operate at mandatory frequency airports to help co-ordinate traffic in the absence of air traffic controllers, and may take over a control tower frequency at a controlled airport when the tower is closed.
In most cases, it is possible to reach flight service stations either by radio in flight, or by telephone on the ground. Recently, some countries, such as Canada and the United States, have been consolidating flight services into large regional centres, replacing former local flight service stations with remote communications outlets (RCOs) connected to the centres.
Famous quotes containing the words flight, service and/or station:
“What a cunning mixture of sentiment, pity, tenderness, irony surrounds adolescence, what knowing watchfulness! Young birds on their first flight are hardly so hovered around.”

“I introduced her to Elena, and in that life-quickening atmosphere of a big railway station where everything is something trembling on the brink of something else, thus to be clutched and cherished, the exchange of a few words was enough to enable two totally dissimilar women to start calling each other by their pet names the very next time they met.”
—Vladimir Nabokov (1899–1977)
