Weather Radar Tutorial (Network)

If you are running FMGS over the network you will need to share the WXR folder in your Jeehell FMGS folder. FMGS will only write weather data information on the Visual Generator (VG) computer (the PC running P3D or FSX). You will also require Active Sky Next or Active Sky 2016.


In this setup the Flight Simulator runs on a client computer (the VG) and another computer over the network (the Server computer) runs FMGS server and the navigation panels (PFD, ND). You will be required to turn on Windows sharing and enable read access (for the purpose of this tutorial Windows 10 is used and the WXR directory is set with read and write access although JL has confirmed only read access is required on the computer running navigation panels). Passwords have been disabled to simplify the process — you may wish to specify a user that can access the folder if you are not running over a secure network.


When you install FMGS on the VG ensure you have clicked the Master FSX/P3D PC dialogue box.

Go to Network and Sharing Center | Advance Sharing settings | Password protected sharing | Turn off password protected sharing

Right click on the WXR folder inside the FMGS folder and go to the Sharing Tab | Advance Sharing | Share this folder

Next, in the Sharing tab, click on the Share… button. Type in Everyone and click Add.

Run Configure.exe in the FMGS directory and Click on the WX Radar path box and select the A320 weather directory.

Now on the Server computer you should be able to access your network shared folder. Using File Explorer | Network | Computer Name | WXR should be accessible with full read and write access.

Run Configure.exe on the Server computer and select the mapped WX Radar path.

** FSUIPC and other utility programs which use the ASN weather data write function can interfere with the FMGS weather radar. Make sure you disable these features. For FSUIPC look in the FSUIPC4.ini file in the Prepar3D\Modules\ directory and ensure the command line “ASNwxRadarPath=” is not present.

Now you don’t have any excuses not to avoid nasty weather! The Airbus Safety First magazine featured the weather radar which you can read about here.

  1. Hi Omni Atlas, my setup is a little different:
    1st PC: P3D, FMGS SERVER, Default shared folder WXR.
    2nd PC both NDs, WXR setting= \\SERVER_NAME\WRX (I can access this manually)

    Search for an airport with precipitation in AS16, today was SBCG somewhere in Brasil, so tilt degree is the only I can see on NDs during a litle flight there. There was 9 dat files in WXR folder in 1st PC 800KB each, but no prcpt image on NDs in 2nd PC.
    What is wrong?


  2. Hi Leonidas – have you tried the weather radar in flight (moving aircraft)? I also had some issues with the weather radar not updating with the aircraft stationary. Regards.
