Opening the MCDU Remote Display

Important Requirements - READ FIRST

Please note the following requirements before trying to use this feature:

The default port is: 8380

This is valid for all options listed below. If you would like to change or confirm the port configuration of SimBridge, see our port configuration documentation.

Option 1: simbridge.local

Supported operating systems

This feature is only available on Android 12 and newer, recent versions of macOS and iOS, and Windows 10 and 11, but it may work on other operating systems that support mDNS resolution.

If you are running an older operating system, proceed to Option 2.

You can easily open the Remote MCDU on any supported device connected to the local network by navigating to http://simbridge.local:{PORT}/interfaces/mcdu in your browser of choice.

Having issues on a supported device? Make sure Option 2 or 3 works, and if they do, take a look at the simbridge.local troubleshooting section. Otherwise, see the general network troubleshooting section.

If the default port is being used: http://simbridge.local:8380/interfaces/mcdu

Option 2: Tray Icon

You can directly open the Remote MCDU from the system tray by selecting "Open MCDU" in the context menu when using Right Click with your mouse.


You can then copy paste this hyperlink or send it to another device (via browser functions) in order to more easily access the Remote MCDU.

Option 3: Web Browser

You can also open your browser of choice and navigate to http://{Computer's Local IP Address:{}Port}/interfaces/mcdu

How to Use the MCDU Remote Display

The MCDU Remote Display can be used by mouse or touch, depending on your device.

It is also possible to click on the MCDU screen items themselves to actually click the corresponding LSK (Line Select Key).

You can hold the CLR key for > 1.5 sec to clear all the scratchpad's content, as it is possible in the cockpit itself.

Changes done in the MCDU Web Interface will be reflected immediately in the cockpit and vice versa. Any change in the cockpit will be immediately shown in the MCDU Web Interface.


You can combine several display options, described below, to get combined effects. For example, ?fullscreen&sound will enable sound and full-screen modes.

Fullscreen Display

If you only want the MCDU display to be shown, then tap on the top-most part of the MCDU display. To return to the full MCDU view, tap anywhere on the display.

If you want to start with only the MCDU display visible, then add ?fullscreen to the URL.


You can enable click sounds when pressing buttons on the MCDU by adding ?sound to the URL.

Day and Night Mode

It is possible to switch between a day and night mode MCDU visualization be clicking/touching the BRT/DIM button on the Web MCDU.

4:3 Aspect Ratio Compatibility Mode

If you are using MCDU hardware with a 4:3 display, you can use the 4:3 aspect ratio compatibility mode to improve the formatting so that the lines align better with your hardware.

To use this mode, add ?43 to the URL.
