I tried it today at EDJA with wind 33 g 51 reported on METARS. It was no gusts at all. I posted a clip of the test with live weather and custom weather with the reported winds in the thread if you want to see it. If the METARS or meteoblue reports a specific wind they should inject that value.
The test i did was in headwind thats why it’s not pushing me sideways but you can see the fluctuation in airspeed better. That is gusts. In crosswind gusts should look like the one i posted here above in an earlier video with custom weather used only, that wind fluctuated between 20-40kts.
