Hello,

Out of interest, why do you want to do this?

Pretty sure it uses the GFS model.

There is no way to permanently disable the integration of forecast winds aloft. This is one of the core SkyDemon features, and we have no plans to introduce a feature which disables it. You can specify your own manual wind values, but this is not persistent when you save and reload the route.

The reason to disable wind forecasts is to make the planning deterministic and ensure no magic-things-happening-behind-my-back-without-my-full-understanding-or-consent.

SkyDemon doesn't compute forecasts or conjure them out of METAR or TAF data. We use an established forecast model (the Global Forecast System). It has been used for aviation purposes since its inception, indeed I believe that was one of the reasons it was started. It's what is used by aviation across the globe as a source of the most reliable predictions of wind vectors aloft.

If there were a lot of people who didn't want SkyDemon to automatically use these wind forecasts, we'd probably have an option to turn them off.

What I do if I plan a route in advance, is just to inverse it ... and the time average will be, in principle, the same as the one with wind 0...

'The necessity to click several times and set 0/0 manually each time I plan a route is much inconvenient.'

Unfortunately not. If you have a significant crosswind component the averaged times will NOT reflect the time achieved with no wind.

However that may be, personally, I don't need this option.

On all SkyDemon platforms you can set an "override wind" for all legs of 0/0 at the same time. There should be no need to go through doing it for each leg.
