The 50% factor has now become even more of a mess.
Now, if one sets the weather in the weather UI, at ground level for a given wind speed, it does now indeed set the weather to have that ground speed , (Noe UI now says GROUND WIND)
BUT now ATIS reports 200% that wind speed !!
Somewhat EGO boosting, because the ATIS reports wind as a 20 Knot cross wind (Difficult in a C172 !!), it’s quite easy (as its only 10 now), but one thinks they are so skilled to be able to handle that ATIS reported 20 knot cross wind !!
Things get even more messed up with Real Weather Winds, so much so, that Active Sky has recognized that, and have a setting to override Asobo’s 50% wind reduction when AS injects the weather. so when AS gets a Metar that says winds 240 @ 10, it injects a 10 knot wind at ground level, and not a 50% reduced one like Asobo weather seems to,
So ATIS winds , then matches actual ground level wind speed in the sim.
