I'm learning X-Plane 11 and started to use an add-on called FS Economy.
One of its missions is to fly to small airports that I can't find on skyvector, so I'm unable to plan a direct flight.
I usually fly to the nearest charted airport, and fly using the GPS from there. Not knowing any information like runway length beforehand.
How realistic is it in the real world that an airport would not be charted, and how are flights planned to such airport?
