was the Fleet Air Arm of the Royal Air Force, featuring albatross wings instead of the wings of an eagle, as per the RAF design. The Fleet Air Arm wings badges also feature a crown and fouled anchor, reflecting the naval aspect of the flying undertaken. They are worn on the left sleeve of naval aviators, above the rank "rings" as opposed to on the left breast of uniforms, like the RAF and Army Air Corps. Unlike the RAF and the Army Air Corps, Naval aircrew are awarded their wings after Operational Conversion Unit (OCU), whereupon they are posted to a frontline squadron, the majority of their flying training complete. Therefore, while a Navy and RAF aircrew might take a similar amount of time to reach an operational squadron, the Naval officer has to wait until he has completed his conversion training to receive his wings. Royal Naval Observers are awarded their own aircrew flying badge, consisting of shorter wings either side of a fouled anchor surmounted by a Crown. Royal Naval Aircrewmen are awarded a flying badge similar in shape to the Observer wings, with slightly narrower wings and a similar anchor, but with no crown. Both observers and aircrewmen are also issued Wings upon completion of their OCU, like Royal Navy pilots. All Royal Navy aircrew wear their wings on the left sleeve of the Number 1 dress uniform jacket, above any rank insignia. British Army The Army Air Corps pilot wings are awarded upon completion of the basic helicopter course at RAF Shawbury and a subsequent Army course at Middle Wallop Airfield. Aircrew are then dispatched to their OCU to receive type training on either the Apache attack helicopter or the Wildcat battlefield support helicopter. The Army is unique in the British military in that both Officers and Non-Commissioned Officers can become aircrew and aircraft commanders. The wings are identical for both Officers and Other Ranks, and are worn on the left chest above any medals, similar to the RAF. In all the services, award of wings does not confer any operational capability – this is declared by a front-line squadron once the student has reached satisfactory standard to allow them to be deployed operationally. This milestone, or 'Combat Ready Status', is the threshold necessary for the award of Flying Pay, a discretionary additional salary bonus for aircrew due to the nature of their work. Australia Royal
