Women The RAAF established the Women's Auxiliary Australian Air Force (WAAAF) in March 1941, which then became the Women's Royal Australian Air Force (WRAAF) in 1951. The service merged with the RAAF in 1977; however, all women in the Australian military were barred from combat-related roles until 1990. Women have been eligible for flying roles in the RAAF since 1987, with the RAAF's first women pilots awarded their "wings" in 1988. In 2016, the remaining restrictions on women in frontline combat roles were removed, and the first two female RAAF fast jet fighter pilots graduated in December 2017. Air Force has implemented several programs to assist women who choose a pilot career. Entry to the Graduate Pilot Scheme is open to women who are currently undertaking a Bachelor of Aviation (BAv). Once qualified, women pilots are able to access the Flying Females Mentoring Network. Men and women are required to undergo the same basic fitness tests to become a pilot; however the standards are lower for females. For some roles, the requirement cannot be adjusted for safety reasons. Ranks The rank structure of the nascent RAAF was established to ensure that the service remained separate from the Army and Navy. The service's predecessors, the AFC and the AAC, had used the Army's rank structure. In November 1920 it was decided by the Air Board that the RAAF would adopt the structure adopted by the RAF the previous year. As a result, the RAAF's rank structure came to be: Aircraftman, Leading Aircraftman, Corporal, Sergeant, Flight Sergeant, Warrant Officer, Officer Cadet, Pilot Officer, Flying Officer, Flight Lieutenant, Squadron Leader, Wing Commander, Group Captain, Air Commodore, Air Vice-Marshal, Air Marshal, Air Chief Marshal, Marshal of the RAAF.
