Bea interrim report #2:
Could someone here explain why the 3rd ADS-C attempt 2:01 didnīt give a GPS-position, and why BEA has removed all 3 attempts from the ACARS-list?
Clearly the 02:01Z was via ACARS as they were out of VHF-range.
Copied from BEA:s intrerim-report:
1.9.2 Coordination between the control centres
At 1 h 46, the DAKAR controller asked the ATLANTICO controller for further information regarding flight AF447 since he had no flight plan. The ATLANTICO controller provided the following elements: A332, from SBGL to LFPG, SELCAL: CPHQ.
The DAKAR OCEANIC Regional Control Centre created the flight plan and activated it. The result of this was to generate a virtual flight following the planned trajectory in the DAKAR FIR between TASIL and POMAT. There was no radio contact between AF447 and DAKAR, nor any ADS-C connection. The flight remained virtual.
1.16.2.1 ATC messages
No ATC messages were received or transmitted by F-GZCP. Only three attempts were made to connect up to the Dakar centre ADS-C system and were recorded on 1st June at 1 h 33, 1 h 35 and 2 h 01. The three requests were refused with a FAK4 code, meaning that the control system had detected the absence of a flight plan for this aircraft or that there was a mismatch between the flight plan filed for this registration number, the flight number and the reported position.
