I have created a number of revised default MSFS 2024 airports that are available for download. The thread is located here (with a Discord server invite):

https://discord.gg/skY3r4NyC

The airports have real world, up to date (based on Navigraph Charts) taxiways, runways, taxi signs, taxi designators, painted lines, gate numbers and airline codes. These airports are designed to work properly with a 3rd party ATC app (BATC, SI, FSHUD, AIG TC, etc.). There was no attempt to revise terminals, hangars or other airport buildings, unless a terminal was modified in the real world airport. All editing was done with MSFS 2024 Developer Mode. The main purpose was to allow AI traffic to traverse the taxiway network without becoming stuck. The secondary purpose was to match the real world airport chart as much as possible. If you notice any errors report the issue on the Discord Server. These airports represent the larger facilities by enplanements, except for the largest in each world region. The reason for not including the largest airports is that there are excellent commercial 3rd party versions available for MSFS 2024.

You may also further modify these airports for your own personal use. However, if you revise them and post a revised version online, just give credit to "JAB-Flightsim".

This is exactly the kind of thing that matters more than it sounds on paper. A bad taxiway network can make AI traffic and third-party ATC look much worse than they really are, because everything starts going wrong before the flight even gets moving.

I haven't tried your files yet, but the idea is very useful. I use AIG with FSHud, and airports with clean taxi routing, gate assignments and runway data are a big part of whether the traffic flow feels believable. Nice to see someone tackling the default-airport side instead of only blaming the ATC apps.

Thanks for the initiative. Regarding Say Intentions (SI) that you mentionned, their injected Ai Traffic don't care at all of what scenery is installed in our MSFS. They rely exclusively on their own Taxi Tuner solution: https://www.sayintentions.ai/blog/sayintentionsai-dynamic-tooltips-added-taxituner-v4-released

Thanks. My updates are not specific to which 3rd party addon is being used and are updated on a regular basis.. The SI Taxi Tuner has over 2000 airports updated by the SI community but if one is.missing, the user has to use the SI Taxi Tuner app which requires work in researching airport changes.
