Been a tiny bit since I had it installed and fiddled with it. But from recollection
Whether its simply AIM itself or then preparing to download via OCI, changes are made to my scenery config by creating entries which are inserted at the top of the config. Whether these were scenery cfg or xml additions, I can't recall, but they showed up on my scenery manager program. If I deactivate or remove them, AIM doesn't like it, I get it.
It adds some type of new aircraft config to select AI folders. Not all but some. I suspect as more plans are downloaded for installation that more AI folders will be altered. I can't remember the file name, but it was clearly created after downloading or installing AIM via OCI
It made some type of change to my ATC whereby voices were slowed, even though they were preset at a higher level with EditVoicepack. I think I read a post from someone else that reported the same issue or something similar, I believe there is a checkbox somewhere on the main AIM interface that controls it.
AI flightplans are modified to take advantage of updated airport codes for P3d v5. In a couple of instances, some of those plans lose their connection to specific AI and I have to use AIFP to reassign them to the plan.
There is some type of interference with Reborn Lights whereby after the changes are made, that program looks to scan the AI folder where the OCI AI installs reside, but ignores my default AI folder. I may be able to modify that scan myself, but somehow that's done.
If I choose a manual install of all Flightplans, would that not then keep from making changes to my AI? The AI would be installed to a specific SSD location, but what about the traffic files? Do they automatically write to the sim or can they be compiled and write to another spot?
I think I may just be resigned to going slow and picking what I want. That certainly will almost certainly change with MSFS, reading some of the posts associated to changes to get AI up and running? It made sense to McCoy when he was trying to reconnect Spock's brain, but
