I don’t expect to meet AI aircraft at a remote island airfield, but are there working solutions to bring a typical small town airport to life?
For example when flying in New Zealand. Would love to see at least one or two AI GA aircraft arrive or leave every few minutes.
I read about various solutions and addons, but am not sure to what extent they achieve this.
What is the current state of these solutions? Is the above scenario possible to set up?
Looks like the recently released GAmod - offline version (World overhaul edition) for Microsoft Flight Simulator | MSFS does exactly this… 
There you find more:
Just tested it. Worked great in New Zealand.
Now I’m thinking about a speech recognition ATC solution. 
I’m using the GAmod - offline version and it has made a great difference to GA airports.
Is there a way to use GAmod offline on top of default multiplayer/live traffic or even AIG? I’m not very keen in applying all the numerous changes described in the mod’s installation instructions as I don’t always fly GA and it’ll be a pain rolling everything back etc. I don’t care if I have bot/human aircraft overlapping each other, as the main issue I’m trying to solve is the almost complete lack of traffic in small airports.
I’d also like to test GAmod ELT, but I found that ELT mod always crashes with a 0xe0434352 error which I haven’t solved yet, so that’s out of the question unfortunately.
Yes you can use it with default multiplayer, but not with default live traffic (real time online). You can use it also with any airline ai traffic solution. Currently GAmod and FSLTL is facing some stuttering after su12 launched. Investigating it currently.
