What's needed to make it work


X-Plane 11.10 or above, tested on 11.41 and 11.50 Beta, will be continuously maintained for latest available stable release (not usually for beta releases, 11.50 beta is an exception).
(Sorry, compatibility with X-Plane 10 has been dropped, but the last LiveTraffic v1.5, which still runs on X-Plane 10, is kept available for download. Documentation for v1.50 will also stay available: Make sure to select v1.50 in the top left corner.)

Operating System

  • Ported and tested on Windows 10, latest release.
  • Reportedly works on Windows 7 and 8.1, no guarantees
  • A recent version the "Visual C++ Redistributable for Visual Studio 2019" is required for LiveTraffic to run on Windows. It is often available already, but not necessarily up-todate. Find a Microsoft support article here. Download and install vc_redist.x64.exe. If LiveTraffic doesn't start and Log.txt contains .../Resources/plugins/LiveTraffic/64/win.xpl : Error Code = 126 : The specified module could not be found. then most likely you're missing this redistributable or it is not up-to-date.
  • Developed and tested on MacOS Catalina (10.15)
  • Supposed to work on MacOS Sierra (10.12) upward, however, as of 01-OCT-2021 due to a combination of certificate availability and a macOS system library issue, OpenSky connectivity is only available with 10.15 upward (see post).
  • With MacOS Catalina (10.15) security requirements further increased. See here an FAQ on how to deal with security prompts and startup issues saying library load disallowed by system policy
  • Many thanks to sparker for providing a Docker setup for building Linux. I do not have a Linux runtime environment and cannot test, analyse, or debug Linux-specific issues.
  • LiveTraffic requires a fairly recent Linux environment. The following is known:
    • Successful installations on Ubuntu 18.04 LTS, Arch Linux, Manjaro, Mint 19.2. Packages required to be installed:
      • curl and libcurl3 for networking, often but not always in by default. This makes (with CURL_OPENSSL_4) available. Incompatibilities with libcurl are the most common source of problems, also see below for some hints.
      • xdg-utils needed for opening web pages (help menu and buttons, download link), Ubuntu has it by default.
    • Not working on Lubuntu/Ubuntu 16.04 LTS, Mint 18.1 due to issues with libcurl/CURL_OPENSSL_4.
    • If you are on a Steam-based installation, then the following tip may help you fixing CURL_OPENSSL_4 version issues:
      • For XP11, add the launch option:LD_LIBRARY_PATH=~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu:~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu %command%
      • Here another link to try to understand this all more on Steam (at least on Arch Linux).
    • Here a general tip how to potentially fix issues finding libcurl from a Support forum post:
      • Created a symbolic link between the installed 64 bit file and the directory where LT was looking (take it from the error message in log.txt). In the author's case, the commands looked like this:
        • To find the directory, check the output from locate
        • Then create the link between the directory and Steam (note that your file paths will differ):
          sudo ln -s /usr/lib/x86_64-linux-gnu/ ~/.steam/ubuntu12_32/steam-runtime/pinned_libs_64/
