FROM THE SAME DEVELOPER OF THE POPULAR 737 ADDON, WITH A 4.5/5 ⭐ REVIEW SCORE, FERGO VIRTUAL CDU FOR THE PMDG 777-300ER, 777F, 777-200LR AND 777-200ER IS NOW AVAILABLE, WITH THE SAME PRAISED, EASY TO USE AND RESPONSIVE INTERFACE!
NEW (30/08/2025): ADDED SUPPORT FOR THE 777-200LR
This is the page for the PMDG 777 CDU. If you are interested in the PMDG 737 version, please use the following link: https://flightsim.to/product/fergo-virtual-cdu
Fergo Virtual CDU is a virtual Control Display Unit for MSFS' PMDG 777 aircraft series. It allows you to remote control the plane's Flight Management Computer (FMC) externally with soft-buttons and a 1:1 representation of the display in real time. Accessible through your regular web-browser, you can use it in a second monitor or any other device connected to your home network, such as a phone or tablet.
Main Features:
Web based client
The CDU interface is a web app that uses your regular browser, such as Firefox, Chrome or Safari. That means you can use it in your computer, phone, tablet or any other device connected to your home network and capable of web browsing.
Easy to use
Simply launch the server, navigate to the CDU interface with your browser and you are good to go. The software automatically connects to the game and sets up the client-server communication.
Non-intrusive
Fergo Virtual CDU is a standalone and portable software that requires no installation. Simply extract the contents of the compressed archive into a folder of choice.
Automatic configuration
FCDU will automatically configure the PMDG settings for data broadcast and add the required firewall rules for the client.
Off-line activation
User experience shouldn't be affected by clumsy on-line DRM. Fergo Virtual CDU uses a simple and off-line activation system.
Customizable
As the client is web based, you can customize images, fonts and colors by simply editing the HTML and CSS files (some web development knowledge recommended).
Multiple CDU support
Swap between captain side, first officer or central side with a simple touch to the top of the CDU, where it says "Fergo Virtual CDU". It's also possible to use both sides at the same time if you have two devices connected.

Works great. Got it running on an old tablet which i have by my side as I fly. Got it set up and running in no time. Only problem I had was that the EXEC button wasn't lighting up. After some time trying to figure out why not I decided to try a different web browser. Voila, it lit up as it should do. I should have read the requirements more closely as the problem was my Opera browser. Chrome works fine. Will no doubt buy the virtual 737 cdu when pmdg release the 2024 737 version.

OK the 777 cdu work but the 737 is now 777 cdu with 737 overlay?! what i do wrong?
You can fix this by forcing a page refresh. You can usually do this by pressing CTRL+F5 if you're using the browser on your PC or manually clicking the "Refresh" button on your device's browser (such as phone or tablet). If that doesn't work, you can try to clear the cache from its settings. I pushed an update last week that is supposed to fix this issue. Are you using the most recent version?
yes new version hmm

The fonts are slightly different from those in the game but it's not a big problem. However, the area to be input in the game is represented as □□□□, but this software displays it as..., which affects visibility.
Hi! This problems happens more commonly on devices with non-latin alphabets. I'm working on a fix for this issue, which should be available in the next release ;)

Great Product... Glad they made the 777 FCU so quickly. I have been using the 737 FCU since day 1.

Thank you for bringing us this fantastic addon. I didn't know there was also a 737 version. I wonder if I can get a discount for the 737 after I have bought this 777 version first.
Thanks! I though the discounted price for the 737 was already in. I'll ask the FSTO staff to get this going ;)

Works well. If you use it on a smart phone, it might appear to be too small for some users. Should be better to use this app on a a bigger screen like on an ipad

Haven't done an actual flight with it yet, but I went through the initial CDU config (set POS, Route, Dep/App, etc) and it all worked flawlessly! So can you make one for the Fenix A320? :)
Fenix already have one built in on V2 that you can use on an ipad / iphone
