Can anything be deduced from the inconsistant time intervals
If the ground station initiates the ping then the inconsistent time intervals indicate some issue with the ground station, not with the plane. The question why would SW that is supposed to ping every sixty minutes not do so. The most obvious possibility is that the pings are low priority. So if the ground station is busy handling other traffic then it is waiting until it has free CPU cycles to send the ping.
78 minutes...late because CPU is overloaded
2 minutes...got corrupted data, retry
2 minutes..got corrupted data, retry
70 minutes...late because cpu is overloaded
60 minutes....on schedule
60 minutes....on schedule
60 minutes....on schedule
31 minutes...????
(note that the above is pure speculation on my part)
So it's the last one that puzzles me. I can't think of a good reason off the top of my head why the ground station would be 29 minutes early.
