Why i like it so much

Having used FSXWX for just over a month, here is my honest opinion about this addon.

ITS FREE!!! First and foremost, you do not have to pay a cent to get this up and running. Downloading and installing is simple and all you need is FSUIPC (free version will suffice) installed on your simulator for this to function and inject weather properly.

Moreover, as a person who runs FSX and P3D side by side, it also allows you to simply switch between them in a standalone program by toggling a checkbox. This makes is a lot more convenient as you do not have to maintain several versions of the same software in your hard drive.

Another cool feature i’ve seen is that they’ve modelled wind interpolation extremely well in terms of accuracy, precision and realism which is an added bonus.

So, ill leave the download links below. Make sure you follow the steps in the instructions and you should be good to go. If you have any questions, as always drop a comment below!


  • Flight Simulator X, OR Prepar3D (obviously)
  • SimConnect
  • .net Framework (most likely already installed on your machine)
