Takata,
Do you really think that any people in governmental circles (possible "source" of those leaks) are really that skilled in aeronautics in order to fully understand what the BEA is really working at without being provided with a full and detailed report?
Unless clear and important facts recorded in the CVR channels allowed an analysis that explained why they entered the "complex" scenario (UAS and so on).
Always comes to my mind that after the Selcal tested ok, just 3 seconds later the crew no longer replied 4 callsfrom ACC-AO.
Reminder:
01:35:
43 “ AFR 447 -AIR FRANCE FOUR FOUR SEVEN, thank you.
01:35:46 “ ACC-AO -Welcome, maintaing flight level three five zero,
say your estimate TASIL?
01:35:53 “ ACC-AO -Say your estimate TASIL?
01:35:59 “ ACC-AO -AIR FRANCE FOUR FOUR SEVEN estimate TASIL?
01:36:14 “ ACC-AO -AIR FRANCE FOUR FOUR SEVEN say your estimate
TASIL?
Source: BEA #1 report
I took into account also the fact:
At 2 h 01, the crew tried, without success for the third time, to connect to
the Dakar ATC ADS-C system. And the flight was not transferred between the Brazilian and ACC DAKAR.
