Dedicated Flight Information Frequencies
Any particular FIR will often have one or more dedicated FIS frequencies where aircraft can make first contact for information. The quality of the information that such frequencies can give is tempered by the large geographical area that they cover, and in some more sparsely populated FIRs the frequencies are often not staffed. An FIS might suggest that aircraft contact a more suitable frequency, e.g., a local airport's radar unit, should that unit be in a position to provide a better service. These units often use the callsign suffix "Information".
In some countries, including the United States, an FIS is provided by units known as flight service stations (FSS).

Famous quotes containing the words dedicated, flight and/or information:
“I made no vows, but vows
Were then made for me; bond unknown to me
Was given, that I should be, else sinning greatly,
A dedicated Spirit.”
—William Wordsworth (1770–1850)
“In all her products, Nature only develops her simplest germs. One would say that it was no great stretch of invention to create birds. The hawk which now takes his flight over the top of the wood was at first, perchance, only a leaf which fluttered in its aisles. From rustling leaves she came in the course of ages to the loftier flight and clear carol of the bird.”
—Henry David Thoreau (1817–1862)
“I am the very pattern of a modern Major-Gineral,
I’ve information vegetable, animal, and mineral;
I know the kings of England, and I quote the fights historical,
From Marathon to Waterloo, in order categorical;”
—Sir William Schwenck Gilbert (1836–1911)
