Plain English Meaning
A list of agreed-upon words that stand for letters when you speak on the radio. Instead of saying 'B,' you say 'Bravo,' so the other person hears it correctly even through static.
Full Definition
A standardized set of code words assigned to the letters of the English alphabet, used in aviation radio communication to spell out letters clearly and unambiguously. The International Civil Aviation Organization (ICAO) phonetic alphabet, used in aviation, assigns one distinct word to each letter (Alpha for A, Bravo for B, Charlie for C, and so on through Zulu for Z), so letters cannot be confused over a noisy or weak radio.
Context Anchor
Used during radio calls when spelling aircraft registration numbers, taxiway letters, airport identifiers, or any letter that must be heard correctly.
