In the sequence of ACARS messages are a number of 'silences'. A silence means either that there is no message to transmit, or that the satcomm link is lost. I've been intrigued by an apparent pattern in these silences, which is shown in this
graph.
The red bars mark the gaps in transmission. They are initially spaced at 27 seconds, and 30 seconds after 02:12z. Any significance in this?

EDIT:: Examination of the message timings shows the following:
2:11:00 +15s - Four WRN messages time-stamped 2:10 waiting. Therefore lack of messages was not the reason for this gap.
2:11:27 +15s - One WRN message time-stamped 2:10 waiting. Therefore lack of messages was not the reason for this gap.
2:11:55 +15s - Two WRN messages time-stamped 2:11 waiting to be transmitted before 2:12. Therefore lack of messages was not the reason for the silence until 2:12:10.
2:12:16 +35s - There may have been messages to transmit but that cannot be concluded from the timings.
2:12:51 +17s - Two FLR messages time-stamped 2:11 waiting to be transmitted before 2:13, therefore no reason for silence until 2:13:08.
2:13:14 +31s - There may have been messages to transmit but that cannot be concluded from the timings.
2:13:51 +23s - There may have been messages to transmit but that cannot be concluded from the timings.
