The WebFMC plugin requires X-Plane 11.20+ running on a

  • 64-bit Windows 7 operating system or newer
  • Mac OS 10.14.x (Mojave)
  • Ubuntu Linux 16.04 LTS or 18.04 LTS (64-bit)
WebFMC may work on other Linux distributions, but we cannot guarantee that.

The plugin doesn't impose any extra CPU/memory requirements on the system. It is very lightweight and was implemented with great care about performance.

Web Client

The CDU can be displayed on any modern and up-to-date web browser with JavaScript support, but we recommend the latest versions of Google Chrome on PC or Android and Safari on iOS. No internet connection required, remote device needs to be on the same local network as X-Plane PC.

We'll do our best to keep WebFMC updated for future changes in supported aircraft throughout the lifetime of X-Plane 11, however we reserve the right to withdraw support for a plane if its developer makes incompatible changes that make it impossible.

Should you have any concerns regarding performance needs, network configuration, devices and browsers supported or any other requirements please try free version first. No refund possible.
