I use to fly transatlantic routes most often from Europe to the US/Canada (just nearing the Canadian coast on my way to KEWR on my other computer). I had a strong TAIL wind 80 degrees at 72, not changing direction or speed until about N5540 where it changed to 92 at 89. There is no variation at all, wind is just keeping steady over several hundred miles. I still use 1.6, but I had the same problem with 1.5. I use to fly offline with downloaded weather files.The wind aloft simulation window reads "wind aloft simulation ID distance 9999"I am bound to say that the "real weather" option of FS2002 at least gave me wind/direction variation and usually varying head winds when flying the North Atlantic westbound.Otherwise I love your program, it gives much, much more realism, nice clouds, visibility changes.I think I am missing something?

With both of those versions Offline winds are simulated, if I remember correctly. Update to V1.7 and Offline winds will be actual.Hope this helps,JimActiveSky Support

Ok, I will update and wait for these headwinds to come...
