From an examination of a vliegincident with an Airbus A330 of the Australian airline Qantas, in which 119 injured, has revealed that the reason was an incorrect algorithm in the on-board computer of the aircraft.
On 7 October 2008, an Airbus A330 twice a totally unexpected nose dive. The airliner of Qantas had at that time 303 passengers and 12 crew members on board. By the sudden decreases were 110 passengers and nine crew members injured, of whom 12 serious. Many passengers flew through the cabin and touched, because they have no belt to had, with their heads in lockers and the ceiling. Moreover, it fell short of the cabin road.
The pilots would during the incident have been overwhelmed with incorrect warnings and incorrect indications of the altitude and the speed. Also was the auto-pilot turned off. The pilots knew after an emergency to make an emergency landing at the airport of the Australian place Learmonth.
Australian authorities commissioned an investigation in to the incident. From the research, that more than three years, has proved one of the three speed sensors incorrect information passed to the computer. These decided, after the erroneous input to be processed, to the Airbus to significantly reduce, reports Fairfax Media.
Except the defect of the speed sensor, found the researchers that an algorithm in the onboard computer that the speed info processing, was not able to the incorrect speed information from only one sensor on a right way to process. Two similar incidents would have occurred in an Airbus A330 and A340, coincidentally, both of Qantas. Now would Airbus the software in the computer have changed, allowing researchers to be pretty sure that similar incidents will not happen.
