Mastering Flight Planning with Little Navmap for X-Plane and MSFS

I walk through setting up Little Navmap to plan realistic flights for X-Plane and Microsoft Flight Simulator. After configuring my high-end workstation, I demonstrate creating routes from Tallinn to Copenhagen and Helsinki to Bangkok. I show how to import aircraft performance data, connect live to the simulator, and integrate SimBrief to handle complex airspace restrictions.
I don't have any airspace restrictions set up, so Little Navmap's auto-generated plan implausibly has me flying through Russian airspace.
