JSBSim --script=scripts/c172_test.xml

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, stands apart as an open-source, highly modular, and mathematically rigorous FDM. jsbsim tutorial

— download JSBSim, open the c172.xml , change one coefficient (e.g., CL_de = -0.4 to -0.7), and feel the aircraft become more pitch-sensitive. That’s the power of first-principles flight dynamics in your hands. JSBSim --script=scripts/c172_test
