“Eddyville
Ground, this is Cessna Four Four Romeo Papa with Information Lima at the
terminal, ready for taxi.”
“Four Romeo
Papa, taxi to Runway Six Right, left on Delta, right on Charlie, left on
Foxtrot, hold short of Runway Three Three.”
This
conversation uses the communications alphabet, also called the phonetic or
radio alphabet, for clear and unambiguous radio exchanges. Hundreds of such exchanges occur every day,
and aviation traffic is safer because of this universally understood ABC. But as businesslike and matter-of-fact as the
radio alphabet seems, a closer look shows it is packed with history, romance,
mythology, literature, and the lure of faraway places.
The
International Civil Aviation Organization (ICAO), an agency of the United
Nations, adopted the communications alphabet in 1952. Soon NATO, our own armed forces, and the
International Telecommunications Union (ITU) also adopted the alphabet. For the U. S. Army and Navy, it replaced the
Able Baker Charlie Dog Easy alphabet familiar from WWII movies. The Aeronautical Information Manual (AIM)
specifies in Chapter 4-2-7 that the ICAO phonetic alphabet be used by pilots. The version printed there is actually the ITU
alphabet, which uses Alfa instead of Alpha (Spanish pilots might be tempted to
say Al-pa) and Juliett instead of Juliet (so French pilots won’t say
Jool-ee-ay).
Although
there seems to be a solid American base to the alphabet, with homely names like
Charlie and Mike as well as the patriotic Yankee, we also get hints of the more
cosmopolitan. You may be figuring
weights and balance in pounds, but Kilo is a reminder that there are other
measures—in Lima, for instance, or Quebec, or all over India.
As for
history, Alpha and Delta are taken straight from the Greek alphabet, only a
step removed from an earlier form of writing using stylized pictures, or pictographs. Alpha, for example, derives ultimately from
the Hebrew aleph, which meant ox.
Just turn the capital A upside down to see the ox’s head.
Romeo and
Juliet, of course, are Shakespeare’s star-crossed lovers, children of two
feuding families in the Italian city of Verona.
In the Greek myth, Echo was the nymph who loved the self-absorbed youth
Narcissus, pining away until only her voice remained. And could Papa be Hemingway?
There’s a
whiff of the getaway vacation in Hotel and Golf, and the alphabet suggests a
taste of nightlife: have a Whiskey and dance the Foxtrot. If you can manage the more exotic Tango, you
might prompt a “Bravo!” from the spectators.
So the next
time you use the familiar letters of the radio alphabet, think of its
cosmopolitan cultural background. From
its Greek beginnings in Alpha to the African zest of Zulu, this bunch of
letters gets past the simple ABCs!
