The FLY ArmA III Air Traffic Module makes it easy to create a network of airports.
  What's new: *Initial release version 0001   The number one request from Fly Tanoa Air was to make it useful for other maps and vehicles. Done.   Check out the readme
FLY ArmA III verion 0001
Mission Maker walkthrough video   Demo video from tutorial     NOTES: 

* Included: 3 airport markers. 3 approach vectors. 1 cargo box and 1 traffic marker. A small init block and a great big function library. Also a brief intro.sqf you may configure and use if you like.   * A DEMO mission on Altis (not the one from the tutorial).

* It's possible to add more airports but it isn't a 2 click solution. If you know how, go ahead. If you don't and need help, message me. The next version will make it simple to add more airports. Updates will be to the function library and the module assets will  always remain the same.

* There are extra functions in there and extra functionality within some of the functions which is unused/disabled. If you want something to be different-- different passengers or less often radio updates, for example-- there's probably already a built-in function for that, just look.   * You can absolutely drop this into an existing scenario, just remember to add the init variables and exec the library.   * There's no restriction on  vehicle type so this is already a taxi service / cargo delivery module, too. Just hop in a car and start delivering people from airport to airport (you can reconfigure the names of destinations of course).   * When you open the library the first thing you may think is, "Hey, if I replaced this civilian thing with a military thing, it'd be like a real mission.", and you would be right. I noticed that, too. There is another framework with those edits already made.

* Since this is a community asset, community suggestions for features and script improvements are welcome.   Have fun!
