This addon allows you to interact with the PMDG 737 FMC in Microsoft Flight Simulator 2020 directly from your web browser on your Sims computer, as well as remotely from your laptop, tablet or mobile phone. It can also be used as a screen-only variant for home cockpit users who have built a custom FMC.

This addon is based on the initial and open-source version of the CDU addon created by Lorby and friends and has been published here on flightsim.to with kind permission by Lorby.

For detailed installation instructions please follow the documentation which can be found inside the addon's archive. And there is also a great Video available which explains how to set up the add-on on your machine. A big shout out to Howlingcrazy for that. Cheers Mate!

• Control the 737 FMC from your browser on your desktop PC, tablet or mobile phone
• Works with any PMDG 737-800, -900, -700 and -600 model for MSFS
• Allows the control of both, left and right CDU
• Keyboard input supported (browser window needs to be in focus for keyboard input to work)
• Can also be run as a screen-only variant especially useful for home cockpit users

This addon might also work with the PMDG 737 models for P3D and FSX (NGX/NGXu/NG3) as they share the same SDK for the time being, but as I cannot test these because I don't own any of the mentioned simulators and the PMDG SDK is subject to change anytime soon, I just cannot officially support it. Therefore any questions regarding these simulators won't be answered by me.
