International Code of Signals - Standards

Standards

"The purpose of the International Code of Signals is to provide ways and means of communication in situations related essentially to safety of navigation and persons, especially when language difficulties arise." It has done this by first establishing a standardized alphabet (the letters A to Z, and the ten digits), along with a spoken form of each letter (to avoiding confusing similar sounding letters, such as 'b', 'p', and 'v'), and associating this alphabet with standardized flags. (See chart, right.)

Combinations of these alphanumeric characters are assigned as codes for various standardized messages. For instance, the master of a ship may wish to communicate with another ship, where his own radio may not be working, or the other ship's call sign is not known, or the other ship may not be maintaining a radio watch. One simply raises the Kilo flag (see diagram at the top), or sends the Morse code equivalent (dash-dot-dash) by flashing light; this has the assigned message of "I wish to communicate with you."

One of the elegant aspects of the ICS is that all of the standardized messages come in nine languages (English, French, Italian, German, Japanese, Spanish, Norwegian, and, since 1969, Russian and Greek). That the sender and receiver(s) are using different languages is immaterial; each language has a book with equivalent messages keyed to the same code. This is also useful in radiotelephony, or even when ships are within hailing distance, if there is no common language: a crewman on a burning ship yells "yuliett alfa vour", and a vessel coming to their aid knows exactly what they need: "material for foam fire extinguishers" (that is, the foaming agent). (See de:Flaggenalphabet for the German version of single-letter signals.)

The Code also covers procedural aspects (how to initiate a call, the format of a message, how to format date and time, etc.), how naval ships (which usually use their own codes) indicate they are using the ICS (by flying the Code pennant), use in radiotelephony (use of the spoken word "Interco"), and various other matters (such as how an aircraft directs a vessel to another vessel in distress, and how to order unidentified submarines to surface).

Famous quotes containing the word standards:

    Today so much rebellion is aimless and demoralizing precisely because children have no values to challenge. Teenage rebellion is a testing process in which young people try out various values in order to make them their own. But during those years of trial, error, embarrassment, a child needs family standards to fall back on, reliable habits of thought and feeling that provide security and protection.
    Neil Kurshan (20th century)

    The standards of His Majesty’s taste made all those ladies who aspired to his favour, and who were near the Statutable size, strain and swell themselves, like the frogs in the fable, to rival and bulk and dignity of the ox. Some succeeded, and others burst.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    With his brows knit, his mind made up, his will resolved and resistless, he advances, crashing his way through the host of weak, half-formed, dilettante opinions, honest and dishonest ways of thinking, with their standards raised, sentimentalities and conjectures, and tramples them all into dust. See how he prevails; you don’t even hear the groans of the wounded and dying.
    Henry David Thoreau (1817–1862)
