How do I use FlyByWire remote EFB and web MCDU in MSFS?

SimBridge is a Windows-local companion service that connects supported FlyByWire aircraft in Microsoft Flight Simulator to browser-based remote interfaces. On the simulator PC, open ; from a phone, tablet or another computer on the same LAN, open , replacing the placeholder with the PC’s active IPv4 address.

What is SimBridge, and what do I need?

SimBridge runs on the Windows PC hosting Microsoft Flight Simulator and passes aircraft data to supported browser displays. The phone, tablet or second computer is only a browser client; it does not run SimBridge or the aircraft.

Install both the aircraft and SimBridge through the FlyByWire Installer. The correct SimBridge download is managed there, so there is no need to copy files manually or find a separate web version. Keep the aircraft and SimBridge updated together because an old service may not communicate correctly with a newer aircraft build.

Is there an online version of SimBridge?

No. The page at port 8380 is served locally by your own PC; it is not a public website or cloud service. Internet access is not required for the browser connection once the software is installed, although features such as chart or flight-plan downloads may have their own online requirements.

Do not forward port 8380 through your router or expose it to the public internet. SimBridge should remain accessible only from your trusted local network.

Which aircraft and platforms support SimBridge MCDU and EFB displays?

The FlyByWire remote-display support depends on the aircraft: the A32NX provides its flyPad and web MCDUs, while the A380X provides the corresponding A380-style displays rather than an A320 MCDU.

SimBridge itself is a Windows application. Microsoft Flight Simulator 2020 is available on PC and Xbox but was never released for PlayStation. Microsoft Flight Simulator 2024 runs on PC, Xbox Series X|S, PS5 and PS5 Pro, but the Windows SimBridge service cannot be installed on any console.

There is therefore no SimBridge setup hosted by a PS4, PS5 or Xbox. MSFS has never run on PS4; although MSFS 2024 runs on PS5 and Xbox, those versions cannot host SimBridge. A phone, iPad, Android tablet, Mac or other computer can still act as the browser screen when the simulator and SimBridge are running on a supported Windows PC.

How do I connect the remote EFB or web MCDU?

Test SimBridge on the simulator PC first, then substitute that PC’s active IPv4 address when connecting from another device.

1. Install SimBridge. Open the FlyByWire Installer, install the supported aircraft and install SimBridge. If Windows asks for network permission, allow SimBridge on Private networks.
2. Start the software. Run SimBridge and Microsoft Flight Simulator, then leave SimBridge open while using the remote display.
3. Load and power the aircraft. Enter a flight with the supported FlyByWire aircraft and wait for it to finish loading. Supply electrical power and switch on the relevant cockpit display; the browser does not bypass a cold-and-dark aircraft state.
4. Test localhost. On the simulator PC, type directly into the browser’s address bar. Use http, not https.
5. Find the PC’s IPv4 address. Open Windows Command Prompt, run ipconfig, and note the IPv4 address under the active Wi-Fi or Ethernet adapter.
6. Connect the other device. If the PC address is 192.168.1.42, enter on the phone, tablet or second computer.
7. Select the display. Choose the EFB, MCDU, OIS or MFD interface offered for the loaded aircraft. The available choices depend on the aircraft and build.

Our remote MCDU connection and control guide covers the MCDU-specific workflow once the main SimBridge page opens.

How do I identify the correct address in ipconfig?

Use the adapter that connects the simulator PC to the same router as the remote device. For a wireless PC, this is normally listed under the active Wi-Fi adapter; for a network cable, use the active Ethernet adapter.

• Choose an adapter showing both an IPv4 Address and a Default Gateway.
• Ignore adapters marked Media disconnected.
• Ignore VPN, Bluetooth, tunnel, virtual-machine and vEthernet adapters unless they genuinely carry your home LAN traffic.
• An address beginning 169.254 usually means Windows has not received a proper address from the router. Reconnect the PC to the network before continuing.
• If both Ethernet and Wi-Fi are active, use the adapter on the same local network as the phone or tablet.

Private addresses commonly resemble 192.168.0.27, 192.168.1.42 or 10.0.0.15. The exact numbers will differ on your network. Routers may assign a new address after a restart, so rerun ipconfig if a previously saved bookmark stops working.

What if SimBridge uses a different port?

Port 8380 is the default, but the configured port takes priority. If SimBridge reports port 9000, test on the PC and use an address such as on the remote device.

The number after the colon must match on both devices. A bookmark using :8380 will fail if SimBridge has been moved to another port.

What is the difference between the remote EFB and web MCDU?

The remote EFB reproduces the aircraft’s tablet functions, while the web MCDU or A380X display provides remote access to the corresponding cockpit avionics.

How does this differ from the MSFS 2024 EFB?

For MSFS 2024 Sim Update 5, released in April 2026, SimBridge still serves FlyByWire aircraft interfaces; it does not mirror or control the simulator’s built-in 2024 EFB. Install the FlyByWire package intended for MSFS 2024 through the Installer rather than reusing an old MSFS 2020 installation.

The simulator-level tablet has its own controls and compatibility rules. Our MSFS 2024 built-in EFB instructions cover that separate system.

Why does the SimBridge site not work or show the same error?

The result from localhost determines the next step: if it fails on the simulator PC, fix SimBridge or its port first; if it works locally but not remotely, investigate the network, IPv4 address and firewall.

1. Test the exact local URL. Enter in the PC browser’s address bar, not a search box. If the port was changed, substitute the configured port.
2. Check that SimBridge is running. A repeated connection-refused error normally means nothing is listening at that address or port. Start SimBridge, close any duplicate instance and retry.
3. Check Windows network access. Set the trusted home network to a Private profile and allow SimBridge through the firewall on Private networks. Public-network permission is not required for normal home use.
4. Remove network barriers. Temporarily disconnect VPN software and make sure the phone is not using mobile data, guest Wi-Fi or a different router. Disable router settings called client isolation, access-point isolation or wireless isolation if they prevent local devices communicating.
5. Confirm the aircraft connection. If the page opens but says the aircraft is disconnected, wait for the flight to finish loading and confirm that the selected aircraft is a supported FlyByWire installation.
6. Check electrical power. If the interface frame loads but its display is black, power the aircraft, switch on the corresponding unit and raise its brightness. SimBridge accurately reflects an unpowered MCDU or EFB.
7. Refresh the browser state. Reload the page, return browser zoom to 100%, and clear the site’s cached data if the page is white, incomplete or has misaligned controls. Trying another browser helps distinguish cached data from a service problem.
8. Restart and update both parts. Close SimBridge, update the aircraft and SimBridge through the FlyByWire Installer, then restart SimBridge and reload the aircraft. Updating one while leaving the other running is a common cause of persistent connection errors.

What does a blank SimBridge page mean?

• No page or connection refused: SimBridge is not running, the URL is wrong or the configured port differs.
• Local page works but the remote device times out: the IPv4 address, firewall, VPN or router isolation is blocking LAN access.
• Page opens but reports no aircraft: the flight has not fully loaded, the aircraft is unsupported or its SimBridge integration does not match the installed service.
• Interface appears but its screen is black: check aircraft electrical power, display switches and brightness.
• Empty white page or broken controls: clear cached site data, use 100% zoom, update both components and restart them.

If the same error continues, record the exact URL and compare local and remote results instead of repeatedly retrying the phone. A local failure points to the PC service; a remote-only failure points to the LAN path.

Can I cancel, uninstall or reinstall SimBridge?

SimBridge is optional unless you need the functions that depend on it. You may cancel its installation, or close and uninstall it using the normal Windows installed-app controls; doing so does not uninstall the FlyByWire aircraft.

For the features covered here, removing SimBridge disables the remote EFB, web MCDU and other browser displays. Any additional aircraft feature that explicitly depends on SimBridge will also be unavailable, but the base aircraft can still be loaded and flown.

To restore those functions, reinstall SimBridge through the FlyByWire Installer and allow it on Private networks when Windows prompts. Test again before reconnecting a phone or tablet.
