Concepts ======== This is a work in progress! The concepts documentation covers the fundamental ideas and principles behind JSBSim, such as the structure of aircraft models, the physics of flight simulation, and the design of the API. It will also include explanations of key concepts such as frames of reference, coordinate systems, and units of measurement. .. toctree:: :maxdepth: 1 frames_of_reference Simulation ---------- TBD. Frames of reference ---------- TBD. Units -------- TBD. Properties -------- TBD. Math -------- TBD. Forces and moments -------- TBD. Flight Control and System Modelling -------- TBD.
