So my testing a while ago (SU10 or SU9 maybe even?) was that the wind speed is displayed incorrectly, at least in the weather-wind settings.
Setting a 20km/hr wind should be 11.1kts (20km/h / 1.8 = 11.1kts), but they’ve done the calculation the wrong way around. I’ll need to do further testing when I have a minute or 60 to confirm it on SU11.
It seems to me that setting this 20km/hr wind in the sim actually multiplies this by the 1.8 conversion factor, giving a roughly 36kt wind instead.
I tested this using custom winds, and using wind indicators on the G1000 or Fenix A320 at 2000’ above ground level, to ensure any reduction due to simulated ground friction was taken into effect.
I may be wrong, and it was a while ago. But I look forward to testing this again over the next couple of days.
