Thanks, Andrei, for the reassurance.
In fact I flew LPPT-LPFR yesterday with the ATR. I got that message, but flew anyway. Simply because it is a small hop, and I wanted to try to learn the FMS and stuff like that. I had no problems with flight logger (I did have problems with my internet connection, but that was right after I filed the report [phew]). And the Landing Lights rule bit me in the behind when I was climbing towards FL100, and I thought "Oops, still have my LL on. Quickly, turn them off!" followed by "@%##%*, that was the rule with that other logger, %$#*(*". Ah, well, what's another 100 points on 7500? Ha! But I'm drifting off subject now...
The original post by Alexander was aimed more at the GA planes. As there are none that are FSX compatible in the VFA pool (acc. the table on the site), what would happen if you take a different plane. Say I have a Seneca IV, instead of III. That is not the original EHM plane, obviously, so what would happen with the PP flogger? It must look at the airplane type at some point, and decide that the plane used is not the plane planned. What will happen then? If the info is only recorded in a field without any consequences, than what's to stop me from using my trustworthy ATR instead? Maybe even in a non-EHM livery... See my point? Are any alternatives possible with PP, and if so, then what are the boundaries?
