and provides a clean interface for reading and writing data. Cython-based module that interfaces directly with Pete Dowson’s FSUIPC_User
FSUIPC acts as a bridge between flight simulators (like MSFS 2020, P3D, or FSX) and third-party software. It maintains a 65,535-byte block of memory where specific simulator variables—such as altitude, airspeed, and landing gear state—are stored in fixed locations called .

While FSUIPC was traditionally accessed via C++ or Delphi, Python has emerged as the ideal partner for rapid prototyping and data science in simulation. Python’s clear syntax, dynamic typing, and vast ecosystem of libraries (NumPy for calculations, Matplotlib for visualization, PyQt for GUIs) make it far more accessible than compiled languages. For flight simulation, this means a developer can write a working script to log engine parameters in under 50 lines of code, or build a custom autopilot override in an afternoon. The key enabler is the library (along with its predecessor FSUIPCclient by Justin Teller), which wraps the FSUIPC DLL calls into intuitive Python objects.
