No, he didn't. Here is a quote from that post:
First,the ACARS. The system has been around since the 70s. It transmits engine data to Boeing/Rolls Royce servers through the Iridium satellite link. But here is the kicker. IT TRANSMITS ENGINE DATA REPORTS AT PRE-SPECIFIED EVENTS,NOT ON TIME. It will send a report at gear up, throttle back meaning cruise achieved (1:07am),and gear down.
ACARS is MUCH more than just engine reporting. But I will leave it up to you to do the research.
