Forecast winds aloft at all sorts of altitudes and flight levels are available from many sources. SkyDemon currently uses model data from the Global Forecast System.

Hi all,
I bet this has been asked a million times, but I can't find it. What data sources are used to calculate wind vectors in planning mode (UK). I can see TAFs, METARs etc in the documentation, but guess they are not good enough to calculate from.

Thanks in advance
Colin
