The previous method of using a uniform scalar of the MSL wind speed for higher altitudes didn't offer enough control. In particular, the shape needs to be quite different to skew low, mid, high. This patch reworks that system so the parameters of each distribution are configured per-altitude level. To keep some continuity between altitudes (on a windy day, all levels should have higher wind speeds on average), the wind speed of the lower altitude will be added to the scale value of the higher altitude. Since it wasn't practical to approximate the previous behavior with the new system, this also handles the tuning of each. The low altitude speeds remain mostly unchanged (typically around 5 knots expect for thunderstorms), but the average speeds for other altitudes went up to more closely match the previous intent but without the massive overshoot. At 2000m wind speeds are typically in the 20-25 knot range now, and 8000m 30-50 knots. https://www.quora.com/What-is-the-average-wind-speed-at-different-altitudes has some of the source data, and Quora is the most authoritative source there is. It claims that cruise altitude winds can get "as high as 150 knots", but doesn't claim anything about the average. I had a surprisingly difficult time finding good data for cruise altitude air speeds for non-jet stream paths (though many of our maps are in jet streams), so I just eyeballed it from https://turbli.com/wind-during-flights/. https://github.com/dcs-liberation/dcs_liberation/issues/2861 Fixes https://github.com/dcs-liberation/dcs_liberation/issues/2863.

About DCS Liberation
DCS Liberation is a DCS World turn based single-player or co-op dynamic campaign. It is an external program that generates full and complex DCS missions and manage a persistent combat environment.
Note that DCS Liberation does not support the stable release of DCS. We can only guarantee compatibility with either the open beta or the stable release, and more people play the open beta. DCS stable might work sometimes, but it's untested, and we will be unable to fix any bugs unique to stable DCS.
Downloads
Latest release is available here : https://github.com/dcs-liberation/dcs_liberation/releases

Bugs and feature requests
If you need to report a bug or want to suggest a new feature, you can do this on our bug tracker. In either case, please use the search bar at the top of the page to see if it has already been reported. Note that you may need to remove the filter for open bugs if it's something we've recently fixed.
Roadmap
Our plans for future releases can be found on our Projects page. Each planned release has a Project, and the page for that project has columns for to do, in progress, and done. Items in the Done column are in the preview build for that release. Items in the To do column are planned to be added to that release.

Tutorials, contributors and developer's guides are available in the project's Wiki
Special Thanks
First, a big thanks to shdwp, for starting the original DCS Liberation project.
Then, DCS Liberation uses pydcs for mission generation, and nothing would be possible without this. It also uses the popular Mist lua framework for mission scripting.
Excellent lua scripts DCS Liberation uses as plugins:
- For the JTAC feature, DCS Liberation embeds Ciribob's JTAC Autolase script.
- Walder's Skynet-IADS is used for Integrated Air Defense System.
Please also show some support to these projects !
