Hello,

It would be helpful if there was an option in the Setup menu to permanently disable the automatic wind predictions for route planning (so to assume a zero-wind conditions). Especially useful when planning a route a few days ahead.

BTW, it's not clear to me how does Sky Demon come up with the wind forecasts? The documentation [1] says vaguely:

"SkyDemon knows what the wind is forecast to be doing anywhere on the globe, at all common VFR altitudes and up to 24 hours ahead."

Is it taken from GAMET forecasts, some numeric global weather model (e.g. GFS), or perhaps worked out from METARs/TAFs by using some heuristics? Can the developers please elaborate more on this?

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.
