To create a waypoint follow the next steps:
1. Click on the tab Waypoints and select the option Create waypoints.
2. Fill at least the mandatory fields and press on the Create button.
In case you prefer to not set the coordinates but to choose a location on a map, you can click on the option Map.
Alternatively, you can import a .txt file containing waypoints. In this case, it's only possible to import waypoints type "3" (User Waypoints). For further information about the file format, please refer to the article Airspace file.
