Central Flying School (CFS) is a Royal Australian Air Force training unit, located at RAAF Base East Sale, Victoria. It operates the Pilatus PC-9 turboprop trainer. The school is responsible for training flight instructors, setting flying standards, and auditing flying practices. It is also home to the "Roulettes" aerobatic team. CFS was the first military aviation unit to be formed in Australia, in 1913, when its role was to provide basic flying training. Its current form dates from World War II, when it was re-established to train flight instructors for the Empire Air Training Scheme (EATS).
