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.

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.

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? In short, it solved a widely-observed problem garbled radio communications. It did so by involving many global stakeholders. The design was the result of significant systematic testing and statistical analysis [4]. And the alphabet was adopted by an influential quasi-global organization NATO , which pushed for its international acceptance. In Alexander Bell was awarded the first US patent for the telephone [5]. The first commercial telephones that soon followed were based on fixed wires between two places that wished to communicate. As a young technology, telephony audio quality was full of static and plagued by audio intermittency making it difficult to clearly understand the spoken message. 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].

Some words were hard to understand under poor radio communications and some words were hard to differentiate, such as Delta and Extra. From this problem emerged the first versions of the radiotelophany phonetic alphabet— the alphabet that eventually became the NATO Phonetic Alphabet in

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.

It uses special words to represent each letter of the alphabet. This helps avoid confusion, especially in noisy or unclear situations. This is used worldwide in aviation, shipping, and other areas and is also known as the Alpha Bravo Charlie phonetic alphabet. In the Phonetic Alphabet, each letter has a unique code word. These words are chosen to sound different from each other. This reduces mistakes when speaking over radio or phone. Each word is pronounced in a clear way. This helps people from different places understand each other.

The first commercial telephones that soon followed were based on fixed wires between two places that wished to communicate. Fourth edition, London. 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. Others are: 'colon', 'semi-colon', 'exclamation mark', 'question mark', 'apostrophe', 'quote' and 'unquote'. Washington, D. 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. 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]. As a result, the ICAO created a new, more effective phonetic alphabet that has since been widely adopted by aviation organizations around the world. Baltimore [Note 1]. These practices significantly influenced the success of the eventual NATO phonetic alphabet. Nine , novenine [25]. It is known that [the spelling alphabet] has been prepared only after the most exhaustive tests on a scientific basis by several nations. There is more to the army alphabet then simply code words for letters. Between ships at sea, signal flags are used to stand for letters in order to spell out words. The R's in these two words, as well as at the ends of several other code words, do not need to be pronounced.

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.

Hence, some numbers are pronounced differently from their standard English pronunciation, such as three as tree tri , five as fife, and nine as niner. To ensure that a communication that involved numbers were received and understood correctly, the pronunciations of certain numbers were modified to avoid confusion.

Retrieved 27 December In short, critical radio communications were sometimes impossible to understand, because they had become muddled and obscured [8]. Name Changes Since the creation of the spelling alphabet, it has undergone several name changes along with character changes. The adoption of the ICAO alphabet allows pilots to effectively convey their location, estimated time of arrival, crew service requirements and aircraft tail number.
