What is the NATO Phonetic Alphabet?

The NATO Phonetic Alphabet (formally the International Radiotelephony Spelling Alphabet) is a set of 26 standardized code words assigned to the letters of the English alphabet (Alfa, Bravo, Charlie, Delta, etc.) designed to prevent audio miscommunication across radio and telephone channels.

Why is it spelled "Alfa" and "Juliett" instead of "Alpha" and "Juliet"?

The official international ICAO/NATO spellings use "Alfa" and "Juliett" so non-native English speakers across international aviation (like French or Spanish pilots) do not mispronounce "ph" as "p" or fail to pronounce a single trailing "t".

How are numbers pronounced in radio telecommunications?

Standard aviation numbers have specific pronunciations to avoid radio confusion: 3 is "TREE", 4 is "FOW-ER", 5 is "FIFE", and 9 is "NIN-ER" (to distinguish nine from the German word "nein").

Can I spell out mixed numbers and symbols?

Yes. The converter handles mixed alphanumeric combinations, hyphens, and spaces cleanly.

Is my input text private?

Yes. All spelling conversions occur directly in your local browser using client-side JavaScript. No passwords or names are ever sent to remote servers.
