True.. and a good clarification. On Air France the systems are coupled and if you are flying with a known defective system then there your route planning (ETOPS limited) is affected so they would not fly into known blind spots. Of course it could have happened en route. But again you have made a fair point. The flight seemed to have sent a msg to MCC indicating a short circuit..again I have a feeling this will be clarified to something specific. But that would be a ACARS transmission. For an accident or an incident its always multiple causes. 3 techies(false media reporting) or an AOG recovery from Rio?
