If picky means the another company 747 and not the Captain Sim 707, then I don't know what picky means. In any case, I have not tried to add the CIVA into the 707, so I don't know how hard it is. As I understand it, the 3D object is a dummy, and you a use pop-up window. I remember using the CIVA a long time ago with the late lamented RFP 747 and it was frustrating with lots of gotchas, as I recall, but did work well once I had it figured out. It is a very intimidating piece of kit. I'll be sticking with Doppler as soon as I figure out how to make it work (oh, please let there be no "issues!") Speaking of which, I got weird smoke -- see the 707 section.
