The NATO phonetic alphabet, officially the International Radiotelephony Spelling Alphabet, is an internationally recognized set of names for the letters of the Latin alphabet and the Hindu-Arabic digits. It is most commonly used in radio communication, where the usual names of the letters are likely to be misheard. It was defined in 1955–1956 by the International Civil Aviation Organization (ICAO).

Mayday is an emergency procedure word used internationally as a distress signal in voice-procedure radio communications.

LORAN (Long Range Navigation) was a hyperbolic radio navigation system developed in the United States during World War II. It was similar to the UK's Gee system, but operated at lower frequencies in order to provide an improved range up to 1,500 miles (2,400 km) with an accuracy of tens of miles. It was first used for ship convoys crossing the Atlantic Ocean, and then by long-range patrol aircraft, but found it
