Virtual CDU 737 is an add-on for your flight simulation that makes your smart device into a CDU capable of interacting with a compatible flight simulator. The app connects to the flight simulator via WiFi connection and uses VA Interface to send inputs to the FMC.
With the app you can navigate through CDU pages, input a flight plan and performance data. It has a up to date worldwide database, allowing to use actual SIDs, STARs, procedures, routes and fixes.
You can get your VIrtual CDU 737 for iOS and/or Android devices on App Store and Play Store.
*The application is not stand alone, it requires a flight simulator to work.
