One of the black boxes from Germanwings flight 4U9525 has been recovered. It’s damaged, but officials say it can still be used to retrieve information. That’s a relief, because so far, no one knows what happens to the plane that crashed in the French Alps en route from Barcelona to Düsseldorf.
A fact that’s undisputed is that the Airbus 320, the downed Germanwings model, is a highly computerized plane. But this by no means renders this aircraft immune to accidents – only months prior to the Germanwings crash one of Airbus’ best-selling airplanes went down over the Java Sea: The AirAsia flight that crashed in December 2014 en route from Indonesia to Singapore was an A320-200.
The computer-controlled plane
Experts are looking to the plane’s black box for answers
Aircraft models from the A320 family rely on aviation software to a much higher degree than most Boeing models.
“The A320 is an almost complete fly-by-wire system, which means that the computers actually fly the aeroplane,” David Stupples, professor for electronic and radio systems at City University London, told DW. “The computer has absolute control over most things.”
There are several computer systems on board the plane, such as interfaces for navigation and communication. They are all connected to the central system that controls the aircraft. This means that each A320 is carrying a huge network of computers with highly complex software.
The software is provided directly by Airbus and is updated regularly to meet the necessary technical and security standards. What’s more, everything
