Compare the best flight simulators for Ubuntu, including X-Plane 12, FlightGear and Aerofly FS 4, with native support, strengths and caveats.
The best flight simulators for Ubuntu are X-Plane 12 for serious civil flying, FlightGear for a free open-source simulator, Aerofly FS 4 for smooth performance, GeoFS for quick browser access, and War Thunder for combat. X-Plane 12 is our best overall choice because it combines native Linux support with the strongest procedural depth.
Which Ubuntu flight simulator should you choose?
The right choice depends on whether you prioritise realistic aircraft systems, cost, performance or combat.
| Simulator | Ubuntu support | Best for | Main limitation |
|---|---|---|---|
| X-Plane 12 | Native Linux application | Realistic civil aviation, IFR procedures and serious home cockpits | Some third-party plugins and installers support Windows only |
| FlightGear | Native and open source | Free civil flying, experimentation and configurable setups | Aircraft quality and systems depth vary between models |
| Aerofly FS 4 | Native Linux release | Fast loading, fluid performance and straightforward flying | Smaller aircraft and add-on ecosystem than X-Plane |
| GeoFS | Runs in a web browser | Casual flying without a large installation | Requires an internet connection and offers less systems detail |
| War Thunder | Native Linux application | Accessible aerial combat and multiplayer | Not a civil aviation or cockpit-procedure simulator |
X-Plane 12 is the strongest Ubuntu option for practising approaches, using real-world checklists or building a hardware cockpit. Its core simulator is native, but Linux compatibility must be checked separately for each aircraft, scenery installer and compiled plugin. Our Ubuntu installation and Vulkan troubleshooting guide for X-Plane 12 covers the setup in detail.
FlightGear is the best free choice. It offers worldwide flying, configurable weather and a large community-created fleet, but an advanced aircraft can be substantially more complete than a basic or older model. Our assessment of FlightGear's realism and aircraft quality explains where it excels and where extra setup is needed.
Aerofly FS 4 suits people who value responsiveness and a simpler route from installation to flying. It is less compelling if a particular airliner, airport or specialist plugin is essential, so check the available content before choosing it over X-Plane.
Are these flight simulators native to Ubuntu?
X-Plane 12, FlightGear, Aerofly FS 4 and War Thunder have native Linux versions, while GeoFS runs in a compatible browser. Native support is preferable because it avoids the update failures, graphics translation and peripheral quirks associated with running a Windows simulator through a compatibility layer.
A Linux version does not guarantee that every Ubuntu release, add-on or controller utility is supported. Simulator developers may validate only selected distributions, and specialist yokes or panels can depend on Windows-only configuration software even when their basic USB axes and buttons work in Ubuntu.
Can Microsoft Flight Simulator run on Ubuntu?
Microsoft Flight Simulator 2020 and Microsoft Flight Simulator 2024 have no native Ubuntu versions. Compatibility-layer installations may work under particular hardware and software combinations, but launcher changes, online services and graphics-driver differences make them poor choices when reliability matters.
Dual booting or using another supported platform is usually more dependable. We cover the trade-offs between compatibility tools, dual booting and streaming in our Microsoft Flight Simulator on Ubuntu explanation.
How do you avoid common Ubuntu flight simulator problems?
- Confirm graphics support first. Install a supported graphics driver through Ubuntu's normal software channels and verify that Vulkan works before troubleshooting the simulator. A missing or incompatible Vulkan driver commonly causes a blank window, immediate exit or device-selection error.
- Run the unmodified simulator once. Complete the first launch and create a basic flight before adding aircraft, scenery or plugins. If a later launch fails, remove the newest addition rather than reinstalling everything.
- Check controller detection at operating-system level. Use
lsusbto confirm that Ubuntu sees the device. If it appears there but not in the simulator, inspect device permissions, then remove duplicate axis assignments and calibrate inside the simulator. - Try an Xorg session when input misbehaves. Wayland can cause mouse capture, focus or window-position problems in some simulator and desktop combinations. Testing the same application under Xorg quickly separates a display-session issue from an aircraft or controller fault.
- Verify Linux add-on binaries. A Windows-only
.dllplugin will not become compatible simply because the host simulator runs on Ubuntu. X-Plane plugins need a Linux binary, while scripts, liveries and scenery can still fail when their files use inconsistent capitalisation on Linux's case-sensitive file system. - Read the simulator log before changing settings. Look for the last aircraft, plugin, library or graphics component loaded before the failure. Making one change at a time preserves the evidence and prevents unrelated fixes from creating a second problem.
Is Ubuntu a good operating system for flight simulation?
Ubuntu is a good flight-simulation platform when the chosen simulator and essential add-ons have native Linux support. X-Plane 12 and FlightGear can provide a complete civil-flight setup without Windows, and standard USB joysticks, throttles, pedals and yokes often work as ordinary input devices.
The main compromise is the narrower commercial add-on and peripheral-software selection. Before committing to Ubuntu, check the exact aircraft, navigation-data service, weather tool, plugins and cockpit hardware you intend to use—not just the base simulator's platform list.
