eyespied - Yes they receive the Queens Warrant but are listed behind real Warrant Officers in the Air Force List.
Chief_Two - Does that mean they are junior to WOs in the same way a Sergeant Major is junior to a Command Sergeant Major in the US Army, even though both are E9s?
Master Aircrew, Warrant Officer and WO1 are all of equal rank/seniority.
Warrant Officer is listed above Master Aircrew on the Air Force List as it is the most common senior non commissioned rank across the service.
