Introduction: Why JSBSim? In the world of flight simulation, the "physics engine" that dictates how an aircraft responds to control inputs, wind gusts, and atmospheric conditions is known as the Flight Dynamics Model (FDM). While many simulators rely on black-box, pre-compiled DLLs or lookup tables, JSBSim stands apart as an open-source, highly modular, and mathematically rigorous FDM. #include <FGFDMExec
