JSBSim is a open source flight simulator (“flight dynamics model (FDM)”) that runs on Microsoft Windows, Apple Macintosh, Linux, IRIX, Cygwin (Unix on Windows), etc. Its features include: fully configurable aerodynamics and a propulsion system that can model complex flight dynamics of an aircraft. Rotational earth effects are also modeled into the dynamics.
To run this example, simply run the following command in the root of the PX4-Autopilot repository
make px4_sitl jsbsim
