Do we have proof the A/C lost ALT indications? Or just the Speed? Because Speed ind loss will not afect Alt indication. On the other hand, Alt ind loss would alter the speed. Plus, the Speed (pitot) sensor is more prone to weather influence (dynamics) than Static (vacuum actuation and flushed) sensors. Any problem in any of these sensors would fail the ADR part of ADIRU. And in fact ALL we know is that an ADIRU reported faulty in the IR part (#2), as well as an ADR DYSAGREE, which can be due to Alt, Spd, or both.Just because we discuss many scenarios does not necessarily make it true, unless YOU'RE THERE!Looks like an established fact that speed sensors caused it (by reading most of the threads in this Forum), and what is most strange is the lack of self-defense from AIRBUS part on the subject.We should all show a bit more respect for the families involved, the professionals involved, and WAIT FOR THE INVESTIGATION TO FINISH!But I have to keep stopping myself to come here, this was just a reminder!
