When writing to offsets, you must ensure the data is packed correctly. For instance, to set the autopilot altitude, you might write a 4-byte integer to a specific offset. Some offsets are read-only, while others can be written to modify simulator behavior.
To get started with FSUIPC and Python, you'll need to:
The library uses "offsets"—hexadecimal addresses—to find specific data points in the simulator. You can find these in the official FSUIPC Offset Mapping documentation Example: Getting Position & Altitude # Use a context manager to handle connection/closure # Prepare specific offsets (Offset, Type) # 0x560: Latitude, 0x568: Longitude, 0x570: Altitude = fsuipc.prepare_data([ ( ), ( ), ( = prepared.read() print( latitude longitude altitude ) input( fsuipc python
while True: line = ser.readline().decode().strip() if line == "GEAR_TOGGLE": # Toggle landing gear (offset 0x0BEC, byte 0 = 1 for up, 0 for down) fs.write(0x0BEC, b'\x01') # Toggle event print("Gear toggled") time.sleep(0.1)
You would need to write a read lvar request to offset 0x0D70 to get the actual value of the lvar. For example, if an aircraft has an LVar called L:XMLVAR_Something , you would: When writing to offsets, you must ensure the
is a high-level programming language known for its simplicity and vast libraries.
The most common way to bridge these two is the fsuipc Python client wrapper , which acts as a middleman between your Python scripts and the FSUIPC tool. To get started with FSUIPC and Python, you'll
The most common Python wrapper is fsuipc , which provides a simple interface to the underlying C-based FSUIPC library. Install it via pip on PyPI : pip install fsuipc Use code with caution. Note: This library is designed for Windows platforms. 4. Understanding FSUIPC Offsets

The most popular Python library for FSUIPC is (or fsuipc on PyPI). Install it via pip:
To start, you need the FSUIPC interface software installed on your machine and the Python library in your environment. : Download and install FSUIPC7 for MSFS or the appropriate version for your sim. : Run the following command: pip install fsuipc 2. Basic Script Example
