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 >1.5sec to clear all of 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 fullscreen 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 in 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.

Compatible Browsers

With hundreds of different browsers available today it is not possible to test and support all browsers and their different versions.

In general we expect this feature to work with the common modern standard browsers on Windows, iOS, Android.

However, there will be browsers where this will not work. In this case we recommend to use a standard browser.

We have tested these browsers (current versions) during the development and these should therefore work ok:

  • Windows: Edge, Firefox, Chrome
  • iOS: Safari, Firefox, Edge, Chrome, duckduckgo, Brave, Bing
  • Android: Chrome, Edge
  • Mac OS: Safari, Firefox, Edge, Chrome
  • Samsung phone: Chrome, Firefox, duckduckgo
  • Linux: Firefox
  • Amazon Kindle Fire HD 10 : Silk
    (App Version Android 5.1.1, Fire OS

Always use the latest versions of the operating system and the browser.

We have not tested older operating systems or browsers and can't support them. They might or might not work.

Known unsupported operating systems or browsers:

  • Samsung Internet Browser
  • iOS 9.x, iOS 10.x
  • Very old browsers not supporting Web Sockets. See Can I use Web Sockets
