Can you elaborate what you tested and when? surface winds? which airport?
are you sure you’ve seen significant airspeed fluctuations and not just mechanical turbulence ?
If you haven’t seen this bug post, I strongly suggest to update your findings there : [BUG LOGGED] No wind gusts for Live Weather, broken for both PC and Xbox
There are many people eagerly waiting for this to really work as it used to pre-SU4, and I’ve been thoroughly testing this even since it’s gone.
