Most of us know, or at least have heard of the military alphabet in some way.

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.

The International Radiotelephony Spelling Alphabet , commonly known as the NATO phonetic alphabet , is the most widely used set of clear code words for communicating the letters of the Roman alphabet. The ITU phonetic alphabet and figure code is a rarely used variant that differs in the code words for digits. To create the code, a series of international agencies assigned 26 code words acrophonically to the letters of the Roman alphabet , with the intention of the letters and numbers being easily distinguishable from one another over radio and telephone, regardless of language barriers and connection quality. The specific code words varied, as some seemingly distinct words were found to be ineffective in real-life conditions. Although spelling alphabets are commonly called "phonetic alphabets", they should not be confused with phonetic transcription systems such as the International Phonetic Alphabet. It is known that [the spelling alphabet] has been prepared only after the most exhaustive tests on a scientific basis by several nations. One of the firmest conclusions reached was that it was not practical to make an isolated change to clear confusion between one pair of letters. To change one word involves reconsideration of the whole alphabet to ensure that the change proposed to clear one confusion does not itself introduce others. The same alphabetic code words are used by all agencies, but each agency chooses one of two different sets of numeric code words. In practice these are used very rarely, as they are not held in common between agencies. A spelling alphabet is used to spell parts of a message containing letters and numbers to avoid confusion, because many letters sound similar, for instance "n" and "m" or "f" and "s"; the potential for confusion increases if static or other interference is present. For instance the message "proceed to map grid DH98" could be transmitted as "proceed to map grid Delta-Hotel-Niner-Ait". The unusual pronunciation of certain numbers was designed to reduce confusion as well. In addition to the traditional military usage, civilian industry uses the alphabet to avoid similar problems in the transmission of messages by telephone systems.

They are used to spell words when people speak over the radio or telephone, when people from different countries are speaking with different accents, or in other situations where people may not clearly hear the normal names of the letters. This is important for accuracy in the military and in air travel and shipping. For instance, it may be difficult to hear whether a person is saying the letter "pee" P or "bee" B. The NATO code words "papa" and "bravo" are much clearer. Each code word begins with the letter that it stands for. Although it is commonly called a "phonetic alphabet", it is not used for phonetics as the International Phonetic Alphabet is. For this reason it is also called a "spelling alphabet".

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. Because the latter allows messages to be spelled via flags or Morse code , it naturally named the code words used to spell out messages by voice its "phonetic alphabet". The name NATO phonetic alphabet became widespread because the signals used to facilitate the naval communications and tactics of NATO have become global.

Most of us know, or at least have heard of the military alphabet in some way. We hear it being used in war and actions movies, video games, and even in comic books and novels. But most people have no idea why it is used, how or why it was formed, or why it has become one of the most effective forms of tactical radio communication — not only in the U. Long before the modern military alphabet was created, the ITU International Telecommunication Union had created the first spelling alphabet to be internationally recognized. Several changes were made to the original version of the spelling alphabet in The new and improved version was then adopted by the International Commission of Air Navigation and was used for civil aviation purposes until the beginning of WWII. Before both forces starting using the ICAO phonetic alphabet in , the British and American military agencies had developed their own spelling alphabets. In , in order to have a comprehensive way for communications between all military branches, the American alphabet eventually became known as Able Baker.

Both authorities indicate that a non-rhotic pronunciation is standard. This section needs additional citations for verification. Several of these documents had revisions, and were renamed. According to a report on the subject:. Further studies were conducted that lead to the changing of five words within the alphabet: C, M, N, X, and U. 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?

Like the letters, the objective is to prevent any misunderstandings with numbers that have a similar sound. In , the US, British, and Australian forces adopted a modified version of Able Baker and successfully used it to coordinate efforts for the rest of the war [1]. All in all, hundreds of thousands of tests were carried out [1]. For example, when testing alternatives for the word Foxtrot, Football scored slightly higher than Foxtrot in articulation, but was found to be more easily confused with Hotel and Victor [9]. Retrieved 22 August Retrieved 27 December Archived PDF from the original on 27 February 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. Here we begin to see good design practice emerge more clearly.
