So far I can't tell about object density. you may need revising issue above.
Static planes are ok. Just sparsely, so it does give space to real-ops. Besides, too many static planes, or planes mislocated may be obtrusive to play on the area.
The UPS plane you located is great. just there giving some structure, but in a place no-one will feel obstructed

Don't add the plane of the remote (JAFVA) terminal just yet. 1) lets wait for the bldg to be constructed. --- I'll work on that one. and 2) I want to add one of these there (for which I may need to create the AI - livery)

I know D-LASER created the peach traffic files at Kansai. I wonder whether he already has the proper A332 static with the proper suit-code.
