Data extracted from the France 2 TV news

I have just colored each seats on an A330 plan from the stills. With a thought for each of these. I only numbered 33 individuals. Available in private.

- about the CVR/FDR, if they are located in the tail of the aircraft (probably thought to be the safest place in most cases ?), in this case they may have been in the area absorbing most of the impact energy. The flight data are armored but the ULB/pinger (little cylinder on the armored box) does not seem very hardenned: could it be that these ULB were damaged at the impact and have never pinged at all ?
- about the false stall alarm recognition : is it easy to discriminate between the pre-stall buffeting and the effects of turbulence ?
can a rapid loss of 300 ft (like in the Air Caraïbe case) reinforce the idea of an on going stall ?
- about the ACARS not transmitting possible stall alarms : we cannot be certain that these have occurred, but they did in several past cases involving Pitot freezing (with little delay after the A/P & A/THR off), and we know that they could be a natural consequence of corrupted airspeeds (using AoA and airspeeds to generate the stall alarm in alternate law 2). If the "stall - stall - stall" was generated in a similar manner to the other cases, then this may have occured as early as 02:10 or 02:11Z, and the overspeed may have been initiated as early as 02:10Z through the A/THR chasing airspeeds that were roling back (increased/max thrust from 02:10Z).
- about the colored seats: after correction, there are 38 colored seats on the BEA map (38 passengers + the 2 crew members)
