I know the weather thing has been beat to death and this will probably get merged into some topic.
However here’s my situation, just looking at wind.
Actual IRL as reported by local ATIS wind 3kts
Asobo Real weather in game reports as 5kts
REX reports as 9kts
And to top it off ATIS reports as 15 KTS!!!
All wind reported is from a different direction. So what is the actual wind 
interacting on the airplane!!!
WHO KNOWS!!! this is why I’ve been screaming and will continue that real weather is so broken in this sim I just have no idea how it will ever be fixed.
Just enjoy and move on I guess.
