Hello everybody.
When I create an ICAO flightplan and check the "addressing" feature, I notice that an automatic address is calculated for my plan.
The AFTN code  selected is the one of the nearest airport to my airfield.
In my case it is LIAUZPZX which is a minor unattended airport.
According to the AIP of my Country (Italy), the flightplans for my area should be sent to Rome Fiumicino LIRFZPZX.
Now the question is; in order to have my flightplan properly processed by SkyDemon and the AFTN network, should I necessarily add as an extra address the Rome Fiumicino AFTN code LIRFZPZX?
In other words, what happen if I leave only the SkyDemon preselected code?
Thanks
Sebastiano
