Attention: this app relies on real, FREE, open ADS-B data rather than FR24 data. Consequently, traffic coverage may be incomplete or entirely absent in many regions of the world. Furthermore, the quality of the traffic display depends directly on the quality of the incoming data; I cannot guarantee perfectly smooth or precise aircraft movement, as this is beyond my control - though I do everything possible to optimize the way the movement is rendered.


LiveTraffic MSFS

LiveTraffic MSFS brings the aircraft that are flying right now into Microsoft Flight Simulator 2020 and 2024. It reads public ADS-B feeds and replays each real flight along its actual track, about a minute behind real time, using FSLTL, FS Traffic and AIG models. If you know TwinFan's LiveTraffic for X-Plane, the idea is the same. This is an independent project built for MSFS.

It's for simmers who would rather share the sky and the apron with real flights than with the default AI.

What you get

1. Real tracks, not AI logic. The arrivals and departures at your airport are the ones on the flight-tracking map, flying their real paths.
2. Proper runway work. Departures line up, roll down the centreline and rotate. Arrivals fly a 3° glide path, touch down in the touchdown zone and brake.
3. Taxiing on your scenery. Ground movement follows the taxiway layout of the airport you have installed. Pushback is shown as the aircraft moving backwards.
4. Landings that don't vanish. When coverage drops on short final, the aircraft still lands and clears the runway.
5. Ground traffic that sees you. Aircraft stop behind you and behind each other, so departure queues form on their own.
6. A living apron. Free stands fill with parked aircraft of the airlines and types that actually serve that airport. Freighters go to the cargo ramps.
7. Your airport first. On the ground or at low altitude, traffic at and around your airport is created before anything else.
8. A map window with flight cards and search. You can hide or remove any aircraft, or keep your own stand free.

Why install it

The default sources need no keys, no sign-up and no subscription. What you see out the window really happened a minute ago, and every flight gets a real runway, glide path and taxi route.

Limitations

The data is replayed with a deliberate delay of about 60 seconds. Between position reports the program interpolates, so each path is a smooth approximation of the real one, not an exact copy.

Coverage near the ground is the weak point. ADS-B often drops out for 40–90 seconds on the ground. Taxi routes are rebuilt from the taxiway layout and may differ from the route actually taxied. A landing completed after the data dropped out is reconstructed, not recorded.

Models come from FSLTL, FS Traffic or AIG. When the right type or livery is missing, a related type or another real airline's livery is used instead. FSLTL has light GA aircraft only in white, so they are hidden by default. There are no helicopter models.

MSFS ATC doesn't see this traffic, airborne traffic doesn't avoid you, and there are no jetways or ground services.

Traffic depends on adsb.fi and adsb.lol, which provide open data for non-commercial use. OpenSky is optional, and without your own account it allows very few requests. When a service is down, the traffic it supplies is gone too.

Every aircraft is a full sim object updated every frame. If your frame rate suffers, lower the display radius and aircraft limit in the settings.

So far it has been tested mostly in MSFS 2024.

Requirements

1. Windows with MSFS 2020 or 2024
2. FSLTL, FS Traffic or AIG models in Community folder.
3. An internet connection
4. WebView2 Runtime for the app window (without it, the window opens in your browser)

Node.js is included in the download.

Installation

Unpack the archive into any folder, for example C:\LiveTraffic-MSFS, but not into Community: this is a standalone program. Install models from FSLTL FS Traffic or AIG into the community folder. Run start.bat before or after MSFS and load into a flight. Traffic appears after a one-minute buffer. Don't run other injectors at the same time, or every aircraft will appear twice.
