Usage wit Aerofly FS 4

This manual is for Windows 10/11 installations. On other operating systems these steps are similar, but the file system locations will be different.

  1. Open Aerofly FS 4, set up a flight plan, choose a aircraft, set time and weather. (You may want to use the Aerofly Wettergerät to get weather data.)
  2. Start the flight and check if the position of your aircraft is correct.
  3. Quit Aerofly FS 4 so all your settings will be saved to your main.mcf configuration file, usually located at C:\Users\…\Documents\Aerofly FS 4\main.mcf.
  4. Web version:
    1. Open and point the tool to the main.mcf.
  5. Local version:
    1. Open the explorer and point it to the directory main.mcf is located, e.g. Documents\Aerofly FS 4\.
    2. Right click on the folder name and choose "Open in terminal".
    3. Run aerofly-missions in the open terminal to convert main.mcf to a tmc file (see below).
  6. Grab your exported tmc file with all your settings converted into a single mission file. This file can now be placed into the custom mission directory in Aerofly FS 4.

Be aware that right now Aerofly FS 4 accepts custom missions exclusively from within …\Aerofly FS 4 Flight Simulator\missions\custom_missions_user.tmc. See installation instructions on how to get started.

See the custom missions documentation for more information. See also more sources for flight plans on the Internet.
