Aircraftman ranks below leading aircraftman and has a NATO rank code of OR-1. It is now a training rank only and no airmen in productive service hold this rank. Aircraftmen do not wear any rank insignia.
The rank was introduced to the RAF in January 1919, replacing the rank prefixes of "Air Mechanic", "Private" and "Clerk" that had been introduced under Air Memorandum No 1 in March 1918. There were three grades: Leading Aircraftman (LAC), Aircraftman 1st Class (AC1) and Aircraftman 2nd Class. A similar grading existed for junior ratings in the Royal Navy.

In RAF slang, aircraftmen are sometimes called "erks".
Royal Canadian Air Force
In the Royal Canadian Air Force, the rank is also known by the French term of Aviateur. This was changed from private in spring 2015 when the RCAF changed the colour of its rank insignia from gold to pearl grey. It is the lowest rank in the RCAF. Prior to 1968 the rank of aircraftman was used in the RCAF as in other Commonwealth air forces.
