Key FSUIPC Offsets for Python Developers

To effectively use FSUIPC, you need to understand offsets. An is simply an address in a large table where the simulator stores a specific piece of information. For example, the offset for the aircraft's ground speed is 0x02B4 , which is a 4-byte value representing 65536 * meters/sec .

The primary strength of using Python with FSUIPC is the depth of control. You aren't just pressing buttons; you are manipulating memory offsets. If the simulator tracks a value (from the battery voltage to the exact position of a flaps lever), you can read it. This allows you to create custom logic that the default simulator doesn't support. For example, you can write a script that says: "If the battery voltage drops below 24V and the engines are off, automatically trigger a master caution light."

When working with FSUIPC and Python, keep these best practices in mind: import time # Conceptual wrapper library from fsuipc

You can also send commands to the simulator. For example, setting the autopilot altitude.

For a comprehensive list of offsets, consult the FSUIPC SDK documentation. 5. Practical Examples: FSUIPC and Python

from fsuipc import FSUIPC import time # Initialize FSUIPC with FSUIPC() as fsuipc: # Prepare the data requests (Offsets are in hexadecimal) # 0x0560: Latitude (8-byte double) # 0x0568: Longitude (8-byte double) # 0x0570: Altitude (8-byte double) prepared = fsuipc.prepare_data([ (0x0560, "d"), # 'd' for double (0x0568, "d"), (0x0570, "d") ], True) # Loop to read data while True: try: latitude, longitude, altitude = prepared.read() print(f"Lat: latitude:.6f, Lon: longitude:.6f, Alt: altitude:.2f m") time.sleep(1) # Read once per second except KeyboardInterrupt: break Use code with caution. Advanced Usage: Writing Data (Controlling the Simulator) An is simply an address in a large

, Prepar3D, and FSX using Python. By utilizing —specific memory locations that store real-time data like aircraft position, engine state, and light status—you can both read the simulation's state and write back to it to control the aircraft. Core Python Libraries

# Open a connection to FSUIPC fipc = pyfipc.FSUIPC()

This script connects to the FSUIPC server, targets the airspeed and altitude offsets, decodes the raw bytes, and prints them to the console.

: Altitude – Needs a conversion formula to feet or meters. Size: 8 bytes (Double).
