Python ((top)): Fsuipc
Because FSUIPC is a Windows-based DLL/EXE, Python developers rely on client wrappers to communicate with its memory map.
lat = fs.read_double(0x0560) print(f"Latitude: lat")
: Do not call sim.read() separately for every individual offset. Declare all required offsets first, and call sim.read() once per loop cycle. This minimizes Inter-Process Communication overhead and prevents simulation stuttering.
— This error often indicates a word length mismatch between the client and server processes. If your flight simulator software is 32-bit, you need to be running a 32-bit version of Python. Similarly, if your flight simulator is 64-bit, you need to run a 64-bit version of Python. fsuipc python
While not FSUIPC-based, this is a common alternative for MSFS 2020 that connects directly to the SimConnect SDK for similar tasks. Getting Started with fsuipc
import fsuipc # Connect to FSUIPC f = fsuipc.FSUIPC() # Open connection to the simulator f.open() # Read Altitude (Offset 0x0570, 8 bytes, Double) # Formula: Altitude (in meters) = Value / 65536 / 65536 alt = f.read(0x0570, 8, fsuipc.FSUIPC_DOUBLE) print(f"Altitude: alt / 65536 / 65536") # Close connection f.close() Use code with caution. Example 2: Setting the Autopilot Heading
You can also send commands to the simulator. For example, setting the autopilot altitude. Because FSUIPC is a Windows-based DLL/EXE, Python developers
: A tiny script is all it takes to see your height in real-time: fsuipc.FSUIPC() # 0x3324 is the offset for altitude in feet = ipc.read_fixed_point( ) print( Current Altitude: altitude Use code with caution. Copied to clipboard ⚠️ The Catch The main hurdle is that FSUIPC is Windows-only
Writing to certain offsets (like engine controls or autopilot) can override user input or cause unexpected behavior. Always test carefully.

, preferably a 32-bit version for maximum compatibility with older simulators. On Windows, the package is named fsuipc and is available on the Python Package Index (PyPI).
📌 Offsets are documented in the FSUIPC Offset Status document.
