Flame out.
RAT deployed.
SATCOM Packs ( are ON/RUN) provides the last (new) "handshake".
IF the report is actually correct.
Does the RAT power SATCOM? For classic Aero it is quite a powerful transmitter, it is not used as a critical flight system, it seems like a waste of RAT power.
My theory is that a momentary loss of power to the SATCOM modem caused it to attempt to re-establish a connection with INMARSAT, which it was not powered for long enough to complete.
