Feature Article: Phonetic Alphabet and Time Zones
In 1914 the U.S. Army adopted a phonetic alphabet but Spanish
pronunciations created problem In 1927 a worldwide agreement
of words and spelling was reached but some words were uncommon.
In 1952 an International Civil Aviation Organization (ICAO) alphabet
was made using Able, Baker, Charlie, Dog but it too had problems.
The current alphabet was adopted in 1956.
Related to this 1996 version are the names of the time zones
around the globe. Alpha time zone begins 7.5 degrees west of
Greenwich, England and extends to 22.5 longitude westward. Each
successive 15-degrees of longitude is given a alphabetic name.
Eastern time is named Echo and Pacific time s Hotel. Even during
daylight savings time the names remain the same. All aviation
time is referenced to Zulu. Zulu time is relative to the sun,
the exact same moment all over the world is recorded by clock
time in Greenwich. Why Greenwich? In 1735 John Harrison, a carpenter
designed an accurate chronometer. By knowing just when noon occurred
in Greenwich with the chronometer, a navigator could use an astronomical
table to determine his longitude.
