Can I use Draken for commercial purposes?

No.

The payware Draken models for Prepar3D as well as the freeware Draken 4.1 (FSX) and 3.2 (FS9) are only intended for personal use and are only sold to private individuals. If you are a company or any other type of organisation you need a commercial license, regardless of how you intend to use Draken. Since 1 March 2024, commercial licenses are no longer offered.
