What you need before you start

The FlyByWire A380 is a free, community-built aircraft add-on for Microsoft Flight Simulator 2020 and 2024. It replaces the default A380 with a highly detailed version that includes a working flight management system, realistic cockpit procedures, and accurate systems modelling. Before you install it, you need Microsoft Flight Simulator already running on your computer, a stable internet connection, and about 25 GB of free disk space.

The installation process uses a tool called the FlyByWire Installer, which handles downloading and placing all the files in the correct location. You do not need to manually move folders or edit configuration files — the installer does this work for you.

Key Takeaways

  • Download the FlyByWire Installer from flybywiresim.com, not from the Microsoft Store or any other source.
  • The installer automatically detects where Microsoft Flight Simulator is installed and places the A380 files in the right folder.
  • After installation completes, restart Microsoft Flight Simulator and the A380 will appear in your aircraft list.
  • If the aircraft does not appear, verify that your Community folder is enabled in the General Options menu under the Developers section.

Download the FlyByWire Installer

Go to flybywiresim.com in your web browser. On the homepage, you will see a button labeled "Download Installer" or similar. Click it and save the installer file to your Downloads folder or anywhere you can find it easily.

The file is called something like FlyByWireInstaller.exe (on Windows) or FlyByWireInstaller.dmg (on Mac). Do not rename it. Once the download finishes, you are ready to run it.

Run the installer and select the A380

Open the FlyByWire Installer by double-clicking the file you downloaded. The installer will open a window and begin searching for Microsoft Flight Simulator on your computer. This usually takes a few seconds. If it finds your installation, it will display the path — for example, C:\Users\YourName\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages.

Once the installer detects Flight Simulator, you will see a list of available aircraft. Find the A380 in that list and click the checkbox next to it to select it. You can select other FlyByWire aircraft at the same time if you want — the installer will download all of them together.

After you have selected the A380, click the "Install" or "Download" button. The installer will begin downloading the aircraft files. This can take 10 to 30 minutes depending on your internet speed.

Wait for the download to finish

The installer will show a progress bar as it downloads the A380 files. Do not close the installer or shut down your computer during this time. The window will display the download speed and an estimated time remaining.

Once the download finishes, the installer will automatically place all the files into the Community folder inside your Microsoft Flight Simulator installation. You will see a message confirming that the installation is complete. At this point, you can close the installer.

Restart Flight Simulator and verify the aircraft appears

Close Microsoft Flight Simulator completely if it is still running. Then open it again. When the main menu loads, go to the aircraft selection screen and search for "A380" or scroll through the Airbus section. The FlyByWire A380 should now appear in your list with a distinctive livery or label showing it is the FlyByWire version.

If the A380 does not appear, the most common reason is that the Community folder is disabled. Open the General Options menu, scroll down to the Developers section, and make sure the box next to "Community folder" is checked. Then restart Flight Simulator again.

Troubleshooting if the A380 still does not appear

If you have enabled the Community folder and restarted Flight Simulator but the A380 is still missing, check that the installer placed the files in the correct location. Open File Explorer and navigate to your Community folder. On Windows, this is usually at C:\Users\YourName\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages\Community. You should see a folder named something like "flybywire-aircraft-a380-freeware" or similar.

If that folder does not exist, the installer may not have detected your Flight Simulator installation correctly. Run the installer again and pay close attention to the path it displays. If the path looks wrong — for example, if it points to a different drive or an old installation — you can usually click a button to manually browse for the correct Flight Simulator folder.

If the folder exists but the aircraft still does not appear, try deleting the Community folder's contents and running the installer one more time. Occasionally a partial or corrupted download can cause this issue, and a fresh installation resolves it.

Starting a flight with the FlyByWire A380

Once the A380 appears in your aircraft list, select it and choose your departure airport and weather conditions as you normally would. The FlyByWire A380 includes a detailed startup procedure — you cannot simply press the start button and fly. The aircraft requires you to go through a realistic cold-and-dark startup, which means turning on electrical systems, hydraulics, and engines in the correct order.

If you are new to the FlyByWire A380, the community has published startup guides and tutorial videos. These show you the exact steps to get the aircraft ready for flight. The learning curve is steeper than the default aircraft, but the realism and detail make it worthwhile for serious flight simulation enthusiasts.

Frequently Asked Questions

Do I need to own Microsoft Flight Simulator to use the FlyByWire A380?

Yes. The FlyByWire A380 is an add-on for Microsoft Flight Simulator 2020 or 2024. You must own one of those versions to use it. The add-on itself is free, but the base simulator is not.

Will the FlyByWire A380 work with my existing Flight Simulator settings and add-ons?

Yes. The FlyByWire A380 installs alongside your existing aircraft and add-ons without affecting them. You can still use other aircraft, scenery, and mods. The A380 is just another option in your aircraft list.

How much disk space does the A380 take up?

The A380 typically requires 20 to 25 GB of disk space after installation. Make sure you have at least that much free space on the drive where Flight Simulator is installed before you run the installer.

Can I uninstall the FlyByWire A380 if I change my mind?

Yes. Open the FlyByWire Installer again, uncheck the A380 from the list, and click Uninstall or Remove. The installer will delete the aircraft files from your Community folder. Alternatively, you can manually delete the A380 folder from your Community folder using File Explorer.

What should I do if the installer crashes or freezes?

Close the installer and make sure Microsoft Flight Simulator is not running in the background. Restart your computer, then run the installer again. If it crashes repeatedly, try downloading the installer file again from flybywiresim.com — the file may have been corrupted during the initial download.
