But on the C/L, buried in a postscript to a post a few pages back by

Now, is that a "reminder to follow the procedures", or an urgent message that
the previously advised procedures were wrong ???
If it is the latter, then AF found probable cause in training / SOPs only 5 days after the crash -
who did they tell ?
That AF note says that, in the event of an Unreliable Airspeed Indication (plus a few other similar events):
- Above the safe altitude, whether in the climb or cruise, maintain the given pitch and thrust settings, then work the UAS Checklist without applying the UAS Emergency Procedure;
- Below the safe altitude, apply the UAS Emergency Procedure.
So the questions are, a) what was (in June 2009 when the note was issued) the USA Emergency Procedure, and b) does the new BEA note give any indication that the PF used it, even though he was in the cruise, and then in a climb?
We do know the a/c did not maintain given pitch and thrust; we do not know if the crew worked the checklist.
