RAAF's Elite Aerobatic Display Team
As the RAAF's elite formation aerobatic display team, the Roulettes perform breathtaking displays, using only hand-eye coordination to fly at speeds of up to 590 kilometres per hour. The six Roulettes may experience up to 4.5G (or 4.5 times the normal force of gravity) during a display in their PC-9/A aircraft. When the Roulettes are not showcasing their skills, they teach qualified RAAF pilots to become flying instructors at RAAF Base East Sale in Victoria.
