Australian Air Force flying badges differ from those in the RAF mainly in having a crown on all Flying Badges (not just on pilot's wings) and in normally having blue wreaths. The pilot's flying badge has the letters "RAAF". A similar twin-wing badge, bearing the Southern Cross, was introduced for officer aircrew in 1998, replacing various single-wing flying badges previously worn by commissioned officers; however NCO aircrew continue to wear the old single-wing badges. Some RAAF pilots signed a petition in 1998/1999 in protest of non-pilot "officer aircrew" receiving a double wing. It was rumoured that some serving navigators and war veterans who had previously held the soon to be abolished 'half' wing agreed with the protest. The petition ultimately had over 10,000 signatures, but in the end the petition was unsuccessful. New Zealand New Zealand uses similar insignia to the United Kingdom, except the pilot's wings bear the letters "NZ" instead of "RAF" and the single wing of other aircrew still have the letters of the trade they represent. Currently these are air warfare officer and air warfare specialist (both wear AW), air engineer (E), air loadmaster (LM), helicopter loadmaster (HL), flight steward (FS), air ordnanceman (AO), and parachute jump instructor (a parachute). Air electronics operator (AE) and Helicopter crewman (HC) are obsolete.
