The Salty Simulations 747-8 project is an open source modification for the default 747-8. We strive to improve the default aircraft and we hope that it will eventually become a “high-fidelity” simulation of the 747. All the features, briefly explained, can be found in the GitHub readme, and all the features can be found in the changelogs. At the moment we are a growing community of around 3k members.
If you would like to contribute to this project, either with your skills in programming or providing information / research, we are always looking for that!
