This should have been followed up by a Class 2 fault message between 2:15:00 and 2:15:14 (referring to BEA interim report). That Class 2 Fault message was not received. Since the Aircraft's orientation should have permitted sattellite communication prior to impact - that makes it likely that impact was within a minute post 2:14:14 - making it unlikely that the aircraft was at "medium/high" altitude at 2:14:14.

Salute,

Two other ACARS were "in the pipe" after PRIM1 & SEC1 faults which should have triggered something also before 0215.

But look at the BEA explanation for the end of ACARS:
a) the aircraft crashed. (possible)
b) the ACARS system was inoperative (possible)
c) the was no other ACARS to be transmitted. (false)

b) A power supply failure after 0214:28 could have stopped the ACARS transmission. Consequently, the crash time canot be acertained from the end of ACARS alone.
