Fsuipc Python -

airspeed = fs.read_int(0x02BC) print(f"Airspeed: airspeed knots")

FSUIPC with Python unlocks the full potential of flight simulator automation. Whether you’re building a home cockpit, analyzing flight data, or prototyping AI pilots, this combination is flexible, powerful, and surprisingly easy to learn.

Start small – read a few offsets, log your next flight, then program a button box. Before long, you’ll be creating tools that rival commercial add-ons.

This script logs position, altitude, and speed every second, then plots the flight path. fsuipc python

import fsuipc
import time
import csv
import struct
from datetime import datetime
fs = fsuipc.connect()
log_filename = f"flight_log_datetime.now().strftime('%Y%m%d_%H%M%S').csv"
with open(log_filename, 'w', newline='') as csvfile:
writer = csv.writer(csvfile)
writer.writerow(["timestamp", "lat", "lon", "alt_ft", "ias_kts", "vs_fpm"])
try:
    while True:
        # Read multiple offsets at once (efficient)
        lat_raw = struct.unpack('i', fsuipc.read(0x0574, 4))[0]
        lon_raw = struct.unpack('i', fsuipc.read(0x0578, 4))[0]
        alt_ft_raw = struct.unpack('i', fsuipc.read(0x0570, 4))[0]  # altitude in feet
        ias_raw = struct.unpack('H', fsuipc.read(0x0B70, 2))[0]      # *128
        vs_raw = struct.unpack('h', fsuipc.read(0x07C8, 2))[0]       # vertical speed * 60.48
lat = lat_raw / 1e7
        lon = lon_raw / 1e7
        alt_ft = alt_ft_raw
        ias_kts = ias_raw / 128.0
        vs_fpm = vs_raw * 60.48  # convert to feet per minute
writer.writerow([time.time(), lat, lon, alt_ft, ias_kts, vs_fpm])
        csvfile.flush()
        time.sleep(1)
except KeyboardInterrupt:
    print("Logging stopped.")

fs.close()

Reading offsets one by one is slow. Use fsuipc.read_multiple():

import fsuipc
import struct
fs = fsuipc.connect()
offsets = 
0x0574: 4,  # lat
0x0578: 4,  # lon
0x0570: 4,  # alt
0x0B70: 2,  # ias
data = fsuipc.read_multiple(offsets)
lat = struct.unpack('i', data[0x0574])[0] / 1e7
 airspeed = fs

fs.write_int(0x07CC, 90) # Heading bug offset

⚠️ Writing requires a registered version of FSUIPC. Reading offsets one by one is slow
