Less than one minute of problem
We have to wait for the next BEA report.
If the BEA has published such a report where the PF looks like a dumb, it probably means that the BEA has more infos about the PF fault.
I don't believe that the BEA, with all the international authorities having participated to the work, wouldn't have pointed out a real technical problem.
The Pitot tubes were incoherent for less than one minute.
Since there are still planes in the sky, it is impossible to loose a plane for this only little problem.
