@gkikas-lgpz : Hi, we operate on short routes (15min) until long routes (4h).
You are right to say that we should use the correct forecast of wind on each point (and even at this stage the precision can be discussed but anyway..).
The idea of having a mean wind is to simplify our calculations as would have been done by a human being :
- between points A and B of a route,
- you project the wind vector
- you calculate the total mean wind on the route.
As said, I understand this is not accurate but this could be a way to calculate performances on a route avoiding too many steps (due to the number of grid point)
If you have another way to evaluate the wind along a route I will very appreciate if you share it with me.
Also do you have airlines using your services ?
