Download a free ATC simulator for PC, compare ATC Simulator 2 Demo with ATC-pie, and avoid common installation and compatibility mistakes.
You can download the free ATC Simulator 2 Demo from Fly Away Simulation for standalone radar-control practice on a Windows PC. For a fully free, open-source option, use ATC-pie; it supports offline practice and FlightGear multiplayer, though setup is less straightforward than a conventional installer.
Which free ATC simulator should I download?
Choose ATC Simulator 2 Demo for a simple downloadable introduction, or ATC-pie if you want an open-source application that can support longer-term practice.
| Option | Best for | Main limitation |
|---|---|---|
| ATC Simulator 2 Demo | Standalone radar scenarios, traffic sequencing and a conventional PC download | It is a demo rather than the complete commercial release |
| ATC-pie | Configurable offline practice and FlightGear multiplayer ATC | Requires more setup and familiarity with ATC procedures |
| Browser-based ATC simulators | Quick practice without installing software | Features, realism and saved progress vary |
ATC-pie is the stronger choice when open-source software and multiplayer support matter more than a simple installer. Our ATC-pie setup and configuration guide explains how to obtain it and prepare a first session.
If you cannot install applications on the computer, compare the free ATC simulators that run online instead. These avoid a traditional download, although they are not direct replacements for every desktop controller simulator.
How do I install the ATC Simulator 2 Demo?
The safest method is to download the package locally, extract it if necessary, and run the supplied installer or executable without separating it from its accompanying files.
- Download the package: Save the demo from our download page rather than trying to launch it inside the browser.
- Scan and extract it: Let your security software check the download. If it is compressed, extract the entire archive into a normal folder before running anything.
- Keep the folder structure intact: Do not move only the main executable to the desktop; older applications often expect their data and sound files to remain beside it.
- Try a normal launch first: Use Windows compatibility settings only if the application fails to start or displays incorrectly. Do not disable antivirus protection merely to bypass a warning.
A mistake we see constantly is running a simulator directly from its compressed archive. That can cause missing-file errors, unsaved settings or scenarios that fail to load even though the download itself is complete.
Is the free download the complete simulator?
No. ATC Simulator 2 Demo is a limited demonstration package, not the complete paid edition.
It is still useful for learning the basic workload of identifying aircraft, issuing clearances and sequencing traffic. Choose ATC-pie if you specifically require software that remains free and open source rather than a demonstration of a commercial simulator.
Will it provide ATC inside my flight simulator?
Not necessarily: a standalone ATC simulator puts you in the controller’s position, while an ATC add-on or network lets you fly as the pilot and receive instructions.
ATC Simulator 2 Demo should therefore be treated as a separate radar-control simulation. ATC-pie has FlightGear multiplayer uses, but software intended for Microsoft Flight Simulator, X-Plane or another pilot simulator belongs to a different category. Our comparison of free ATC software for use with flight simulators explains those options and the setup differences.
