In reality wind blows faster at higher altitude. This is very well visible when flying rc helis IRL and might be some motivation to fly lower :) It would be great if it was like this in neXt too.
Also I'm not sure at which altitude the wind speed set in the simulator should take effect (so for example if you set 7 km/h, should it be at eye level, or ground, or where?). But if needed, I could check how it was done in RF - it takes this into account and probably models wind in some good way.
The wind speed in the simulator is always the same ... no matter where you are flying. Especially while you have enabled turbulence, of course, then it will be calculated once for the whole scenery. That should be enough, since the model cannot be at two different positions at the same time.
In reality, this depends on the surrounding obstacles, the terrain and the wind direction. Sometimes the wind in 200m has the opposite direction than the wind in 100m. And sometimes I have the same wind at a height of 30 cm. Depending on the grass height. Yes, I know, the wind is a bit slower on the ground (less than 1m heigh). But as long as turbulence is on, it doesn't really matter. Typically you are flying higher than 1 meter over the ground.
Fine, I didn't know wind simulation is already so complex. I somehow can't really get good feeling of wind, but this is maybe because of some issues in the other thread. I now think the variation of wind with height can't be really the reason..
