Does anybody know if the correct level off altitude was 6800ft (as reported on some sites) or FL068 (as reported on avherald)?
The "data" I saw from FR24 stopped at 6800', did not "level at". Systems showing it levelling off may well be "predictive" when the data stream is lost?
AvHerald had someone deduce an accurate crash location which my Google Earth makes ~5500'. The ridge beyond it GE says is ~6100'. Very roughly, if you take the last FR24 position, the RoD then, and run forward to the crash site, another 1000'-1500' lost is "in the ballpark" (I've not spent a lot of time on this, so do not treat with much confidence).
As I said above, if it was an OP DES descent, the selected Altitude (which the AP would level off at) should have been transmitted over Mode S the whole way down, so the BEA may reveal that later today?
