In June 2009, an Air France flight from Rio de Janeiro disappeared without a trace. The disappearance turned crash and the questions started: how did a state-of-the-art plane go down so suddenly and who was to blame? The plane’s black boxes were finally recovered after two years of searching and there’s a case to be made that the design of the cockpit controls may be at least partially responsible for the crash.
The official report by French accident investigators is due in a month and seems likely to echo provisional verdicts suggesting human error. There is no doubt that at least one of AF447’s pilots made a fatal and sustained mistake, and the airline must bear responsibility for the actions of its crew. It will be a grievous blow for Air France, perhaps more damaging than the Concorde disaster of July 2000.
But there is another, worrying implication that the Telegraph can disclose for the first time: that the errors committed by the pilot doing the flying were not corrected by his more experienced colleagues because they did not know he was behaving in a manner bound to induce a stall. And the reason for that fatal lack of awareness lies partly in the design of the control stick - the “side stick” - used in all Airbus cockpits.
