Human Performance Tools – Phonetic Alphabet

The NATO phonetic alphabet (also known as the ICAO phonetic or spelling alphabet) and the ITU phonetic alphabet, is the most widely used spelling alphabet. It is used by professional communicators, especially police, military and other emergency workers to identify letters precisely, either when communicating initials, abbreviations or spellings of words. It is a commonly used human performance tool in 3-way communication to confirm precise instructions on work being executed.
