I believe that examining everything after 0135, (INTOL) is important. I think the fact that the crew did not respond to DAKAR's request for their TASIL estimate is significant.
Not to belittle your comments, but there is a need to substitute ATLANTICO for DAKAR.
The only time that DAKAR got directly involved in this flight is after after the a/c had passed INTOL and ATLANTICO passed them the a Virtual Flight Plan by AFTN when DAKAR advised they didn't have a Flight Plan for AF447. From memory I believe they had received it but the call-sign was entered into the system incorrectly, and as a result the ADS-C failed to allow the log-on due by 0200z.
DAKARs later involvement was "after the fact".
That ATLANTIO didn't follow-up on their 3 requests for a TASIL estimate by SELCALing the a/c has at this junction of the investigation not been questioned by the BEA, other than noting it as a matter of record. Neither did ATLANTICO attempt to contact the a/c at either SALPU or ORARO, waypoints for which times had been given by AF447.
