I knew I had read about this very topic somewhere on the forums, and it turns out it was my own topic
I'm seeing the same issue in 2024. I'm guessing there were no WT avionics advancements in the new sim, Nick? There's another topic elsewhere on here about some WT v2 avionics, have you looked at those at all?
It's interesting rereading that note, though, that the difficulty lies in the fact that not all of them use the same/default flight planner. That would be the one instance I expect the WT stuff to excel at because of how baked in it is.
