The International Radiotelephony Spelling Alphabetcommonly known as the NATO phonetic alphabetis the most widely used set of clear code words for communicating the letters of the Roman alphabet.

It has been used by pilots, air traffic controllers, military and other professionals around the world for the last 66 years—since —without change [2]. The fact that the design has been internationally adopted, universally used, and endured for decades, indicates there is something good about it. To be clear, the NATO phonetic alphabet was not the first such alphabet, but once its careful development was complete and put in place in , it was widely and rapidly accepted by numerous international organizations and is still the standard today [3]. What made the NATO phonetic alphabet design so enduring that it survived the pre-digital analog age, and the onset and proliferation of the digital age? Why was this design so universal that it is used throughout the world with only minor regional adaptations?

Effective communication is critical to the safe operation of aircraft. This alphabet was created to help pilots and air traffic controllers avoid misunderstandings when communicating via telephone or radio. 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. Have a look at how the aviation phonetic alphabet can be used to convey messages including Morse code. 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. Using the phonetic alphabet helps to minimize any misunderstandings between the cockpit and the tower. In addition to assigning the letters, the ICAO phonetic alphabet also designates specific numbers. Like the letters, the objective is to prevent any misunderstandings with numbers that have a similar sound. Hence, some numbers are pronounced differently from their standard English pronunciation, such as three as tree tri , five as fife, and nine as niner. The adoption of the ICAO alphabet allows pilots to effectively convey their location, estimated time of arrival, crew service requirements and aircraft tail number. 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. 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. ICAO established its phonetic alphabet as a global standard on November 1, , to communicate English letters via radio or phone.

The NATO phonetic alphabet , officially denoted as the International Radiotelephony Spelling Alphabet , and also commonly known as the ICAO phonetic alphabet , and in a variation also known officially as the ITU phonetic alphabet and figure code , is the most widely used radiotelephone spelling alphabet. Although often called "phonetic alphabets", spelling alphabets are unrelated to phonetic transcription systems such as the International Phonetic Alphabet. Instead, the International Civil Aviation Organization ICAO alphabet assigned codewords acrophonically to the letters of the English alphabet , so that critical combinations of letters and numbers are most likely to be pronounced and understood by those who exchange voice messages by radio or telephone, regardless of language differences or the quality of the communication channel.

The Allied military phonetic spelling alphabets prescribed the words that are used to represent each letter of the alphabet, when spelling other words out loud, letter-by-letter, and how the spelling words should be pronounced for use by the Allies of World War II. They are not a "phonetic alphabet" in the sense in which that term is used in phonetics , i. The Allied militaries — primarily the US and the UK — had their own radiotelephone spelling alphabets which had origins back to World War I and had evolved separately in the different services in the two countries. For communication between the different countries and different services specific alphabets were mandated. During WWII, the Allies had defined terminology to describe the scope of communications procedures among different services and nations. Both nations had previous independently developed alphabet naming system dating back to World War I. Subsequently, this second world war era letter naming became accepted as standard by the ICAO in After the creation of NATO in , modifications began to take place.

Probably the two most potentially useful skills I learnt in the army were ironing a skill I try to avoid putting to use at any cost and knowledge of the phonetic alphabet. With the melting pot of languages and accents prevalent in most hospitals around the world — both patients and staff — it is routine to have to spell out words to facilitate communication.

To enable the U. Archived from the original on 29 October And in Muslim countries, where alcohol is more prohibited, Whiskey is replaced by White or Washington [1]. Similarly, in the United States, it is common to say "point" instead of "decimal". That is, may be read as "one three zero zero" e. Tests were focused on word articulation , and word confusability with other words in the set. Juliett [Note 1]. But these development efforts were not centralized. Kilogramme [Note 1]. Confusion among words like Delta and Extra , and between Nectar and Victor , or the poor intelligibility of other words during poor receiving conditions were the main problems. Mission Statement Volunteers serving America's communities, saving lives, and shaping futures. The failure of the modified Able Baker alphabet was rooted in the fact that an international standard was set having only considered three, mostly homogenous, stakeholder groups US, UK, and Australia. New York [Note 1]. Retrieved 30 January When two people speak the same language, they may speak the numbers in their language, even if they use the NATO phonetic alphabet for spelling names.

Effective communication is critical to the safe operation of aircraft. This alphabet was created to help pilots and air traffic controllers avoid misunderstandings when communicating via telephone or radio.

Thus making letters that were previously difficult to distinguish when named such as the letters bee, tee, vee more obvious by saying beer, toc, and vic in their place [7]. During the Vietnam War , the U. Chris Mattson. Madrid: International Telecommunication Union. Pronunciation was not defined prior to We hear it being used in war and actions movies, video games, and even in comic books and novels. The results showed that many of the words in the military lists had a low level of intelligibility, but that most of the deficiencies could be remedied by the judicious selection of words from the commercial codes and those tested by the laboratory. To improve communication over the low-quality connections and possibly long-distance telephone lines of the late 19th century, basic telephone alphabets were developed [1]. After World War II, with many aircraft and ground personnel from the allied armed forces, "Able Baker" was officially adopted for use in international aviation. In short, the alphabet adequately solved a widely-observed problem.
