Python-SimConnect

Python interface for Microsoft Flight Simulator 2020 (MSFS2020) using SimConnect

This library allows Python scripts to read and set variables within MSFS2020 and trigger events within the simulation.

It also includes, as an example, "Cockpit Companion", a flask mini http server which runs locally. It provides a web UI with a moving map and simulation variables. It also provides simulation data in JSON format in response to REST API requests.

Full documentation for this example can be found at https://msfs2020.cc and it is included in a standalone repo here on Github as MSFS2020-cockpit-companion.

Python interface example

from SimConnect import *

# Create SimConnect link
sm = SimConnect()
aq = AircraftRequests(sm)
ae = AircraftEvents(sm)

# Get the aircraft's current altitude
altitude = aq.get("PLANE_ALTITUDE")
altitude = altitude + 1000

# Set the aircraft's current altitude
aq.set("PLANE_ALTITUDE", altitude)

# Trigger a simple event
event_to_trigger = ae.find("AP_MASTER")  # Toggles autopilot on or off
event_to_trigger()

# Trigger an event while passing a variable
target_altitude = 15000
event_to_trigger = ae.find("AP_ALT_VAR_SET_ENGLISH")  # Sets AP autopilot hold level
event_to_trigger(target_altitude)

HTTP interface example

Run glass_server.py using Python 3.
