vol 72 qantas air crash
"Qantas Flight 72 (QF72) was a scheduled flight from Singapore Changi Airport to Perth Airport on 7 October 2008 that made an emergency landing at Learmonth airport near the town of Exmouth, Western Australia following an inflight accident featuring a pair of sudden uncommanded pitch-down manoeuvres that resulted in serious injuries to many of the … The Qantas A330 involved in the accident. This time, because the data spike was over, the elevators responded and the plane started to level out.As the negative G-forces subsided, everyone in the cabin who was pinned to the ceiling came crashing back down again. An altitude value is encoded as a sum of these numbers; the numbers used in the sum are indicated by changing the binary value of the associated bit from zero to one. The plane entered an immediate dive, flinging into the ceiling anyone and anything that wasn’t tied down. Because the exact value of the data encoded in the word depends on what type of data it’s labelled as, the information became corrupted. People slammed into the floor, the seats, and other passengers, falling back down amid a chaotic flurry of random objects.
Mr Maiava says his injuries have changed his life and as a result, is unable to work or drive a car.Mr Maiava now has two titanium knees and seven damaged discs in his spine.For the chronic pain, anxiety, depression and sleep disturbance, he takes around 22 pills a day.He continues to have nightmares and flashbacks to this day.“I keep hitting the wall, just to ground myself,” he said.After getting a medical discharge from Qantas, Mr Maiava said the pain and nightmares got so bad he tried to take his own life.“I ended up in ICU in a coma for a week. These protections normally prevent pilots from making control inputs that could put the plane into a dangerous attitude, and correct a dangerous attitude if one develops. I couldn’t take it any longer, the pain was unbearable,” he said.“I thought to myself ‘what’s happening’? But the faulty data incorrectly triggered two of the alpha floor protections even though the aircraft was in a normal attitude for cruise flight. Picture: AAP Image/Bianca De Marchi.It was the Qantas flight from Singapore to Perth that was brought to the brink of catastrophe.An incident so sudden and unexpected, it’s been deemed the most terrifying emergency in Australian flight history.QF72 was cruising smoothly over the Indian Ocean right before all hell broke loose. While Qantas has never had a fatal jet airliner accident, the Australian national airline suffered several losses in its early days before the widespread adoption of jets in civilian aviation.
How was it possible that ghosts in the code could injure so many people and threaten to bring down a plane on one of the world’s safest airlines? I can’t let you do that,” he told As the Airbus spiralled out of control, Mr Sullivan had to draw on all the skills he had learned as a Top Gun fighter pilot in the US Navy to bring the plane back from certain disaster and save the 315 passengers and crew on board.The plane did a double nose dive that sent passengers, luggage and other items throughout the cabin.Plunging 200m in 20 seconds, Mr Sullivan fought against the dive and pulled on a side stick to stop the descent — but nothing happened. The crew was led by Captain Kevin Sullivan, a former At 12:42:27, the aircraft made a sudden, uncommanded pitch down manoeuvre, experiencing –0.8 The ATSB investigation was supported by the Australian About two minutes later, ADIRU No. 8 déc - Écrasement d'un F/A-18 du corps des marines américain 20 déc - Vol 1404 Continental Airlines However, on the scale used for AOA data, those exact same bits corresponded to values summing to a total of 50.625 degrees.As soon as the error occurred, ADIRU 1 started intermittently sending this mislabeled data to the flight computers.
The exact nature of the corruption was that the ADIRU CPU erroneously A number of potential trigger types were investigated, including software bugs, software corruption, hardware faults, electromagnetic interference and the secondary high-energy particles generated by The ATSB assessment of speculation that possible interference from The ATSB's final report, issued on 19 December 2011, concluded that the incident "occurred due to the combination of a design limitation in the flight control primary computer (FCPC) software of the Airbus A330/A340, and a failure mode affecting one of the aircraft’s three air data inertial reference units (ADIRUs).
