GA traffic is in beta, you won’t see much other than the odd caravan or cj4.
FSLTL injects the traffic, but most of things beyond that is default sim AI behaviour. I think you should see AI aircraft at correct terminals, but gates won’t match. It isn’t live as in live down to GPS location at a gate. You have to use PSXT with a subscription for that info.
FSLTL doesn’t control the pushback, default sim AI does. FSLTL just injects the traffic for default sim AI to use.
Don’t think this is possible, check their FAQ
Again FSLTL only injects traffic for default sim AI to use, the go arounds are inherent in default sim AI. You can try other mods like AIFlow to try to aid this to some extent, but the issue is with default sim AI.
