Voted, I also wish this functionality was there. Either the plane or the World Map should be updated to make flight plans “compatible”.
It’s silly really. The more I use Simbrief the less I understand why some planes can’t recognize the World Map. The route part is exactly the same. Departure airport, SID, intermittent waypoints, STAR, destination. With a few clicks you can recreate the same route on the World Map that you would otherwise do on Simbrief. It must be some data format issue or something. I wish Asobo figured it out, at least on their own aircraft, if they also make the simulator with a built-in flight planner…
