In fact, I seem to be unable to initiate an MLAT on any aircraft unless bidirectional sharing from planeplotter is active. I then see the color-coded "aircraft with MLAT possible" and can initiate an MLAT request. I find that in my aircraft list view, I am unable to select the "Aircraft with MLAT possible" filter unless I select bidirectional sharing.

My 9742 port forwarding goes to the Pi, of course I also have invoked ppupto90 with the "-net-pp-ipaddr 192.168.1.130", pointing to my Planeplotter PC with fixed IP address. I am still a bit puzzled about MLAT initiation from a system where Planeplotter has inherited MU status by virtue of the Raspberry Pi ppup1090 (mode a/c version) MLAT capability.
