What: Qantas Airways Airbus A330-300 en route from Perth in Western Australia to Singapore
Where: Perth
When: Saturday December 27,
Who: The number of passengers and crew has not yet been released.
Why: The autopilot on a Qantas Airways Airbus A330 suddenly disconnected 500 kilometres after taking off. The jet was cruising at 36,000 feet when the autopilot quit. The flight successfully turned and landed in Perth.
This being the second autopilot fault, the situation is being investigated. A prior incident involving an on board system shutoff has been possibly attributed to communications interfering with aircraft onboard systems.
The ADIRU (air data inertial reference unit) is the flight computer system component about which the crew received an error message during the Dec 27 incident.
