Note that on the right hand side of the ACARS where it says NOVO, they all came from AF447
Thats how we know its from that flight, not others.
I am not disputing that the info relates to AF447. I am just raising the possibility that the information is not complete because the supplied report is NOT the actual aircraft report. The report is a ground report produced by someone performing a search. We do not know what filters were applied, if any at all or what was on page 27 or page 30.
Also interesting for example would be to see the information produced for the leg into Rio.
