The RAF radiotelephony spelling alphabet was used by the British Royal Air Force (RAF) to aid communication after the take-up of radio, especially to spell out aircraft identification letters, e.g. "H-Harry", "G for George" etc. Several alphabets were used, before being superseded by the adoption of the NATO/ICAO radiotelephony alphabet. While sometimes referred to as the "RAF Phonetic Alphabet", it is a spelling alphabet rather than a true phonetic alphabet.

History
During World War I both the British Army and the Royal Navy had developed their own quite separate spelling alphabets. The Navy system was full alphabet, starting: Apples, Butter, Charlie, Duff, Edward, but the RAF alphabet was based on that of the "signalese" of the army signallers. This was not a full alphabet, but differentiated only the letters most frequently misunderstood: Ack (originally "Ak"), Beer (or Bar), C, D, E, F, G, H, I, J, K, L, eMma, N, O, Pip, Q, R, eSses, Toc, U, Vic, W, X, Y, Z.
By 1921 the RAF "Telephony Spelling Alphabet" had been adopted by all three armed services, and was then made mandatory for UK civil aviation, as announced in Notice to Airmen Number 107.
Alphabets
Since 1956
In 1956 the NATO phonetic alphabet was adopted due to the RAF's wide commitments with NATO and worldwide sharing of civil aviation facilities.
