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.”
—Georges Bernanos (1888–1948)
“Old books that have ceased to be of service should no more be abandoned than should old friends who have ceased to give pleasure.”
—Peregrine, Sir Worsthorne (b. 1923)
“When, in the course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume the powers of the earth, the separate and equal station to which the laws of nature and of nature’s God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.”
—Thomas Jefferson (1743–1826)
