The phonetic alphabet is one of the first things in aviation that a pilot or air traffic controller learns because it forms the foundation of all spoken air/ground communication.

Up until 1 March 1956 civil aviation in Australia used the British phonetic alphabet which had been extensively used during the war years. However, from 1 March 1956 a more 'international' version of the phonetic alphabet, supposedly easier for people of non-English speaking background to pronounce, was adopted. This new phonetic alphabet is used unchanged throughout the aviation world today.

The table below gives both phonetic alphabets:

Letter	till 1 March 1956	post 1 March 1956
A	Able	Alpha
B	Baker	Bravo
C	Charlie	Charlie
D	Dog	Delta
E	Easy	Echo
F	Fox	Foxtrot
G	George	Golf
H	How	Hotel
I	Item	India
J	Jig	Juliett
K	King	Kilo ('keelo')

M	Mike	Mike
N	Nan	November
