Mr Cissé and Mr Jouty
About 2 minutes after being in cruise, the 280kt cruise speed started to decrease a little. The route was changed as a normal procedure to avoid CBs.
CB heads topped at F380 or higher.
At 01h45 LT (0145 UTC) the aircraft altitude was FL310 and speed 200kt (IAS, I believe).The altitude continued to decrease and the speed also that reached 160K. The end of record is at 01 47' 15'' at an altitude of 1600ft and an airspeed of 380kt.
the last part of the track is, at least at the beginning, the one that was filmed on the radar screen, with a tight left turn initiated and a subsequent continuous left turn until the impact/end of record .
CVR
The CVR recovered is not readable yet because of the band state. The band is by itself in a rather good state but it can not be read because it is altered for an unknown reason, but the fact that the band is not exploitable is not related to the crash by itself. The band will need further and deep analyses and expertises to be readable.
FDR is recording about 80 parameters.
Radar:
The Ouaga radar is a new one. The radar recordings have been saved and should be available for the inquiry.
A question was raised about possible military radar in the crash area. Mr Cissé replied that it will be asked to all States if they have records of this flight on any military radar(s) in the crash sector.
The ASECNA has already identified other aircraft in the area that were in contact with the DAH5017.
A stage report should be published mid-September.
