Simple, definitive license statement

Postby rkjessop » Wed Nov 15, 2017 8:25 pm

Many other websites for simulations or frameworks have a simple link to a page that contains the licensing agreement for their software; e.g., http://www.openeaagles.org/wiki/doku.php?id=license.. I have combed the FlightGear web site and its forum for such a link with such a statement. I have not found one.

Does such a link exist? I have seen the policy document at http://www.flightgear.org/flightgear-policy-document/. This does not satisfy as a legal statement for what I can do with the software. I have seen an indirect statement about LGPLv2 in a document that discusses a commercial knock-off of FlightGear. Again, this does not satisfy as legal statement.

In the source code itself, you should find the license terms for the main FlightGear program (which are GPL.)

Perfect! At NASA, we need to get permission before downloading anything: chicken/egg problem. Thanks, Curt for your quick response!

Note that the GPL version is GPLv2+, as mentioned in the Policy Statement. Though that does not include some public domain works including FDMs originating from NASA ;)

It's good to remember that the very first flight dynamics model used within FlightGear was LaRCsim developed by Bruce Jackson at NASA Langley. His great work literally got our little project off the ground in the very early days! I still pick out Navions when I visit Oshkosh or happen to see them around other places.
