1 Import a flight plan into X-Plane 11
That's easy as can be. It is important that you have created a flight plan in .fms format beforehand. This can be done for example with onlineflightplanner.org. But also extensive tools like simBrief allow an export in .fms format. As soon as you have downloaded the .fms file, you have to move it to the directory X-Plane 11 → Output → FMS plans. Tip: To make the list as clear as possible, it is worth renaming the file as follows: ICAO-ICAO.fms. For example: EDDF-EDDM.fms.
