Welcome to the developer portal

Please visit our forum if you cannot find what you're looking for.
 
 

Get involved!

If you would like to help with FlightGear's development, it's a good idea to subscribe yourself to the FlightGear development mailing list. Use the list or the FlightGear issue tracker to get in touch with fellow FlightGear core developers.

Visit Category:Core development projects to see a list of currently ongoing projects! See Category:Developer Plans to see a list of developer plans for the upcoming release. See request for comments for a list of long-standing issues and challenges affecting FlightGear's evolution and overall development progress (admittedly a little outdated meanwhile).

Help needed: The YaSim FDM is looking for a new maintainer:

Cquote1.png There are some pending merge requests to add some Yasim features, but we have an issue that since none of the current C++ developers own, or are experts in Yasim, we're reluctant to be the person who merges such changes, and potentially introduces subtle regressions.

Obviously this is chicken-and-egg, since no one can become expert enough in the code to become a maintainer :)

So, I'm more than happy to apply patches *providing* I can be convinced they are sane+reasonable from a pure code perspective (happy to help with that, too, if people are new to C++), and providing we have some assurance that a representative sample of yasim aircraft are unchanged or improved by the patch. Suggestions for that means in practice, are most welcome!

Otherwise I worry, given the nature of the solver, we'll keep optimising the solver for some aircraft, and making other existing aircraft worse - until someone tests them, and announced that they're no longer working.[1]

Bugs can always be fixed. What YASim needs is a maintainer, not really expertise per se. The latter comes from the former.[2]
