After that no RR ACARS messages was to be expected for a long time.
So how do they conclude 'disabled' and not just 'not transmitting'?
I would say the ACARS could have been disabled around the same time as the transponder - at 17.21 UTC.
This is the reason they are saying that ACARS was 'deliberately turned off'. It would appear it went through a tidy log off of some sort at 1:07 local. Had it just been failed by circuit breaker then it would just not have reported any more and there would be no time of its disconnect. A tidy shut down means it was not (
name a disaster) and that as the briefings have
repeatedly been told '
deliberately turned off'. That the Malaysian authorities can repeat very simple things and be continually disbelieved only adds to the confusion.
