The FAA table prints the code word for X as "Xray"; NATO's page prints "X-ray". Alfa and Juliett are the official spellings in both.

When it is used

The FAA's manual says the alphabet is used "when communications conditions are such that the information cannot be readily received without their use," and tells pilots to "use the phonetic equivalents for single letters and to spell out groups of letters or difficult words during adverse communications conditions." The same code words spell grid coordinates, call signs, names and serial numbers on military radio nets and over the phone.

Zulu, the last code word, also names a time: the same manual says "the term "Zulu" may be used to denote UTC." The military time converter covers the 24-hour clock.

Where it came from

NATO's own page says the NATO phonetic alphabet "was established in 1956 and just a few years later became the established universal phonetic alphabet." Before it, in NATO's words, "the United States adopted a Joint Army/Navy Phonetic Alphabet, called the "Able Baker" alphabet after the first two code words, across all of its military branches in 1941."

Able, Baker, Charlie, Dog, Easy, Fox, George, How, Item, Jig, King, Love, Mike, Nan, Oboe, Peter, Queen, Roger, Sugar, Tare, Uncle, Victor, William, X-ray, Yoke, Zebra
1951: International Air Transport Association alphabet (civil aviation only)
