FlightGear has no provision to load aircraft from shared libraries. You can distribute your aircraft under a proprietary license, like Vitos does, but not as a shared library. It would take a lot of work to change FlightGear so it can load aircraft from shared libraries. Who would do that work and why would anyone do that when their time could be spent improving free software? And why would the core developers of FlightGear accept such a "contribution"?<ref>{{cite web | |||

You own copyright of your work even if you license it GPL, and you may develop your work further and release a more complete version under a commercial license if you like (that's a variant of dual licensing). The only way to not retain copyright of what you do is to transfer it to someone else or to relinquish it by releasing your work into public domain. If you create a 3d model for a FG aircraft and license it GPL, nobody prevents you from adapting and selling it for X-plane. In fact, you can sell it also for FG (but others may re-distribute it as they like once they buy it since it is GPL, so it may not be a too viable business model) <ref>{{cite web | You own copyright of your work even if you license it GPL, and you may develop your work further and release a more complete version under a commercial license if you like (that's a variant of dual licensing).
