JSBSim is an open-source, object-oriented flight dynamics model (FDM) written in C++ that simulates the nonlinear 6-DoF motion of aircraft and rockets under aerodynamic, propulsion, and control forces. Aircraft are defined via XML configuration files, and the library ships with Python bindings, a MATLAB/Simulink S-Function, and an Unreal Engine plugin.

Use cases

• simulate aircraft flight dynamics in python
• model 6 degree of freedom aircraft physics
• integrate a flight dynamics model into unreal engine
• test autopilot and flight control system designs
• run batch flight simulations without a GUI
• simulate rocket trajectories with earth rotation effects
• connect flight dynamics to FlightGear or Simulink

When to choose

• you need accurate nonlinear 6-DoF flight physics for aircraft or rockets
• you want to define vehicles via XML without writing compiled model code
• you need bindings for Python, MATLAB/Simulink, or Unreal Engine
• you are doing aerospace research, control design, or reinforcement learning for flight

When to avoid

• you need a graphical flight simulator out of the box (JSBSim is console/library only)
• you need real-time 3D visuals without integrating an external engine
• you need simple arcade-style flight physics rather than engineering-grade models
