![]() The decision to create a single universal alphabet was made due to dissatisfaction with the existing internationally recognized phonetic alphabet. ICAO established its phonetic alphabet as a global standard on November 1, 1951, to communicate English letters via radio or phone. The fundamental requirements for the chosen words were that they had comparable spellings in English, French, and Spanish and were valid words in each of these languages. In 19, ICAO’s language sector collaborated with Jean-Paul Vinay, a linguistics professor at the Université de Montréal in Canada, to create a new spelling alphabet. Due to the significant amount of Delta Airlines traffic at the airport, the decision was made to adopt an alternative name or word that would be recognizable and clear to pilots from all countries. It is worth noticing that At Hartsfield-Jackson Atlanta International Airport (ATL), the phonetic alphabet’s use of “Dixie” instead of “Delta” serves to prevent any confusion with Delta, the airline. If they needed to report their estimated time of arrival as 3:25 PM, they would say “Tree Two Five, one five two five Zulu” (Zulu referring to the Coordinated Universal Time or UTC). In such a situation, they would use the ICAO phonetic alphabet and say “Four Zero degrees, three zero minutes North Seven Four degrees, one zero minutes West” to ensure clarity of communication. Implementation of the aviation Phonetic Alphabetįor a better understanding, let’s assume that a pilot needed to report their location as latitude 40 degrees, 30 minutes north and longitude 74 degrees, 10 minutes west. The adoption of the ICAO alphabet allows pilots to effectively convey their location, estimated time of arrival, crew service requirements and aircraft tail number. Have a look at how the aviation phonetic alphabet can be used to convey messages including Morse code. Glossary of the Phonetic Alphabet used in aviation The purpose of using a phonetic alphabet is to reduce the likelihood of confusion and enhance safety measures for both the aircrew and passengers during operations. The words in question are: Alfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee and Zulu. ![]() ![]() The ICAO Phonetic Alphabet, also known as the NATO Alphabet, assigns 26 code words to the 26 letters of the English alphabet in alphabetical order. This alphabet was created to help pilots and air traffic controllers avoid misunderstandings when communicating via telephone or radio. When pilots talk to air traffic control, they use a standardized language known as the International Civil Aviation Organization ( ICAO) Phonetic Alphabet. Effective communication is critical to the safe operation of aircraft. ![]()
