Monday into the Atlantic Ocean show there was an `` indicated inconsistency in measured air speeds , '' Airbus said . The company did not elaborate . Experts said that could mean the pilot 's and co-pilots ' sensors were showing different speeds . `` If they 're malfunctioning , it can give a false read that can be misinterpreted in the cockpit , and a disaster can follow , '' said Peter Goeltz , the former managing director of the U.S. National Transportation Safety Board . While the pilots themselves sent no distress calls , the aircraft 's computer system relayed about four minutes of automated messages indicating a loss of cabin pressure and an electrical failure , according to investigators . Airbus said it sent the Telex Thursday night after the action was recommended by the French investigating agency , which plans to hold a news conference Saturday morning in Paris , France .

RIO DE JANEIRO , Brazil -LRB- CNN -RRB- -- Automated messages sent from Air France Flight 447 just before it crashed Monday indicate the plane 's systems were providing contradictory information about its airspeed , the jet 's manufacturer said on Friday . Friends and relatives of the 228 people aboard Air France Flight 447 attend a memorial service Thursday in Brazil . That suggests the pilots may have been flying too fast or too slow through the violent weather they encountered before the crash , officials said . In addition , investigators have said the plane 's autopilot disengaged , cabin pressure was lost and there was an electrical failure before the disaster . Airbus confirmed on Friday that in the wake of the crash it sent a Telex to operators of all Airbus models reminding them what to do when speed indicators give conflicting readings . The spokesman said the notice does not mean there is any major flaw in the aircraft , but is simply a reminder to pilots about what to do in the cockpit if they get conflicting information about air speed .
