You fly FlightGear. You want interactive air traffic control with human controllers. You want realistic flight plans and routings. You want to take on the challenge of aviating, navigating and communicating — all at once.

SquawkGear lets you do all that and more, connecting FlightGear to the VATSIM network. You can communicate with ATC using text and voice, and you can see other human-piloted aircraft perform takeoffs and landings. You can expect diversions when airfields close due to bad weather, because FlightGear’s weather will follow the network’s.


If you run Linux, FreeBSD, MacOS or any other system with a working Python interpreter, grab the first package. If you run Windows, you probably do not have Python installed, so grab the second package instead.
In all cases, you need SB747 and AVC too.

NEW (For all systems with python installed) Contains python scripts and required XML files. (For Microsoft Windows) Contains a pre-compiled EXE, source python scripts and required XML files.
