Hey I’m an F-16 Crew Chief in real life and I noticed that in 4.34 (and in the .pdf OP created) the Link-16 only extrapolates for 8 seconds between data link responses. This felt wrong, as your flight members will drop of data link for a few seconds between updates, so I went and looked it up in the real -34 and sure enough the extrapolation period is 13 seconds in real life, long enough for friendly members of your flight to stay on your HSI forever. I can’t post the whole manual in its entirety, but here’s the relevant section:
From the -34:
“Between receipt of air PPLI updates, PPLI symbol positions are extrapolated and
updated for a maximum of 13 seconds to minimize excessive jumps in displaying the track position between receipt of the Link
16 update messages. Air PPLI tracks are purged, if an update has not been received for 13 seconds.”
