Python Link — Fsuipc

FSUIPC Python refers to various community-developed libraries that provide a Python interface for FSUIPC (Flight Simulator Universal Inter-Process Communication), an essential tool for interacting with the internal data of Microsoft Flight Simulator, Prepar3D, and FSX. Primary Libraries There are two main ways to use Python with FSUIPC:

Read a simple offset: 0x0D80 contains the SIMULATION STATE (4 bytes)

state = fsuipc.read(0x0D80, 4) print(f"Simulator state: state") fsuipc python

def set_heading(heading_deg): # Heading is stored in degrees * 65536 / 360 (32-bit uint) heading_raw = int(heading_deg * 65536 / 360) data = struct.pack('I', heading_raw) fs.write(0x07CC, data) # Autopilot heading bug fs.write(0x07D8, b'\x01\x00') # Heading hold mode ON print(f"Heading set to heading_deg°") This means the communication is surprisingly fast

3. Speed and Efficiency Python is an interpreted language, but the libraries used (like pyuipc) are wrappers around C/C++ DLLs. This means the communication is surprisingly fast. For reading simple data like airspeed or heading, the latency is negligible, making it suitable for real-time instrument feedback. import fsuipc with fsuipc

While FSUIPC is traditionally accessed via Lua scripting or C/C++, the combination of FSUIPC with Python opens up a world of possibilities — from building custom cockpit instruments to automating flight tests, logging telemetry, or creating AI-driven copilots.

import fsuipc with fsuipc.FSUIPC() as py_fsuipc: # Prepare the offset (0x02BC is airspeed, 4 bytes) airspeed = py_fsuipc.prepare_data("02BC", 4) # Read the data from the simulator py_fsuipc.read() # Process the result (Airspeed is stored as knots * 128) knots = airspeed.value / 128 print(f"Current Airspeed: knots:.2f knots") Use code with caution.

Deep Integration: It allows you to read and write "offsets"—hexadecimal memory locations that represent everything from aircraft speed and fuel levels to switch positions and light statuses.
