In 1920, Sir Willoughby Gwatkin, the former Canadian Chief of the General Staff, was granted the rank of air vice-marshal and appointed the inspector-general of the newly established Canadian Air Force.
In official Canadian French usage, the rank title was vice-maréchal de l'air.
The Admiralty objected to any use of their rank titles, including this modified form, and so an alternative proposal was put forward: air officer ranks would be based on the term "ardian", which was derived from a combination of the Gaelic words for "chief" (ard) and "bird" (eun), with the term "third ardian" or "squadron ardian" being used for the equivalent to rear admiral and major general.
The command flag of an air vice-marshal has two narrow red bands running through the centre.
As of August 2014[update], air vice-marshal was the highest uniformed military rank currently held by a woman in the British Armed Forces when Air Vice-Marshal Elaine West was awarded the position in August 2013.
