More importantly, these two West Germanic languages use almost the same Latin alphabet. It’s still utilized worldwide today.English descends from Proto-Germanic, the same ancestor that birthed the modern German language.Įrgo, it should come as no surprise that both the English and German languages have plenty in common.Īside from the fact that both languages share plenty of words together, their grammar can be quite similar. The words that represented the letters C, M, N, U, and X were substituted, and the final version was approved by the Organization on March 1, 1956. In the wake of this research, as well as the feedback from all ICAO Member States, and in consultation with communication specialists, the new ICAO phonetic alphabet was adopted and integrated into the Aeronautical Telecommunications Annex 10 for application in civil aviation. As a result, the ICAO created a new, more effective phonetic alphabet that has since been widely adopted by aviation organizations around the world. The existing alphabet was submitted to ICAO for review and the organization had concluded that it was not effective in communicating letters and numbers clearly, particularly in international aviation operations. 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. The adoption of the ICAO alphabet allows pilots to effectively convey their location, estimated time of arrival, crew service requirements and aircraft tail number. For instance, when referring to an aircraft tail number like M345N over the radio, it would be pronounced as “Mike, tree, four, fife, November.” Hence, some numbers are pronounced differently from their standard English pronunciation, such as three as tree (tri), five as fife, and nine as niner. Like the letters, the objective is to prevent any misunderstandings with numbers that have a similar sound. In addition to assigning the letters, the ICAO phonetic alphabet also designates specific numbers. Using the phonetic alphabet helps to minimize any misunderstandings between the cockpit and the tower. When communicating using different accents or in difficult circumstances for exchanging information, confusion can arise between two individuals due to certain letters having similar sounds, for instance, M and N, or G and J. Why is it important to use the Phonetic Alphabet in aviation? 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.
