Real time live traffic in MSFS.
PSXTraffic is a new program and the successor of PSXseeconTraffic. PSXTraffic gives a much better out-of-the-box experience and is easier to use, while it has less options and it comes packed with already learned airport files (2286 stock airports and approx. 1000 for third party addons).

The latest version (1.8.0) comes with 7715 (!) already learned stock airport files.
Version 1.9.0 RELEASED
Provides (as an option) on-the-fly learning of airports (just as in the old PSXT programs). You now have the best of both worlds in one program!
There are about 1300 files for third party addon airports that are offline filled with traffic data from RealTraffic in the week July 24 - July 30. Amongst them MK-Studios CYUL
Version 2.6 RELEASED
Finally, after more than 7 years, the AI pilots in PSXTraffic have learned to make real curves when taxiing. They no longer turn over the nosewheel but over the main gear. This was achieved by using quadratic bezier curves.
One of the last criticisms of PSXTraffic now resolved. Have a look yourself, and enjoy real time live traffic!
Version 2.8 RELEASED
Now with a new feature: Live ground traffic at airports you fly over is shown too.
Version 4.2 RELEASED
After eight years I finally managed to put everything in one program: PSXT.exe.
Running the RealTraffic app is no more needed, PSXT gets the traffic and weather data directly from the RT servers.
You now finally run just one program!
This is not only more user friendly, it is also much more efficient because the data coming from the server is processed immediately. There is no need for the RT app to run, consuming cpu cycles, and broadcasting data over your LAN, and then for PSXTraffic to read that back.
Also the number of data asked is tailored precisely around the lateral range that you have set.

Version 6.0 released
Three immersion breakers fixed!
- finally smooth rotate and takeoff rolls
- the problem of small vertically oscillating aircraft (on/in the ground) fixed
- ground aircraft now always spawn with the right heading
Added a possibility to limit the number of live aircraft, for users that face low fps at major airports with lots of traffic

Version 6.1 released
I finally made some changes in version 6.1.0 that will make your (updating) lives easier 
From the release notes:
(!) Removed the archive folders, dbase.xml and AIG-regcodes.txt from the Installer Program. These files will from now on be downloaded and installed automatically by PSXT, as soon as a newer version becomes available.
The PSXT installer is small and fast (again).
(!) A new PSXT version is detected , downloaded and extracted automatically by PSXT. You’ll get this message:
You only have to exit PSXT and run the installer program.
Version 7.4.2 Released
PSXT as static parked aircraft generator!
PSXT, a real time live traffic generator for MSFS and P3D, can now be used without a RealTraffic license subscription (thus completely free!), to populate the airports that you visit with static parked aircraft.
The aircraft will be set at gates based on historic data from week 1, 2024, courtesy RealTraffic.
PSXT parks static aircraft of the right airline, model and livery at the right gate at the right hour and day of the week, no empty airports!
If you fill in your destination airport, the parking starts when the airport is in sight. You can also enter the gate number where you want to park, to prevent it is occupied when you arrive.

Version 8.6.3 Released
Forgot to post here about the updates for a number of months, but we have arrived at 8.6.3…
Several improvements have been made. You don’t have to fill in your destination anymore, there are improvements in the push back procedure, RT has a new server park (v14) and a new RT service called parkedtraffic is operational, to name a few.

PSXT version 9.0.2 released, now with support for MSFS 2024!
I haven’t posted here for quite a while, but development of PSXT has been steadily continuing. The current version is 11.5.2 …
For more information, please visit my website, where you can also find the Manual.
PSXT 15.0 is a substantial step forward, both functionally and under the hood, with a strong focus on realism, usability, and robustness.
A key highlight is the improved integration with RealTraffic, including support for the new token-based licensing and a complete fix of the RT App data buffering. Together with better processing of weekly traffic data, this results in noticeably more airports with live traffic and a measurable improvement in parking quality.
On the realism side, parking has been refined significantly. Aircraft now settle more naturally at the gate with reduced overshoot, and newly added shutdown animations replace the old “instant stop” behavior. In addition, users can now reserve a stand at their destination directly from the UI, making arrival handling much more predictable and controlled.
The collision avoidance logic has been further tuned to do exactly what it should: prevent unrealistic close encounters below 7000 ft without interfering with realistic traffic flow or ATC behavior. Above that altitude, responsibility remains with the pilot and TCAS, keeping the simulation authentic.
Usability has also taken a big leap. The main window has been redesigned with a cleaner layout, improved spacing, and a new compact mode that dramatically reduces screen footprint during flight. Startup behavior is more flexible, airport scanning can be automated, and several long-standing UI quirks, including 4K scaling issues, have been resolved.
Finally, there are important technical improvements behind the scenes. Support for encrypted airport files with smart local caching reduces unnecessary downloads and enables easy local editing and testing. Combined with multiple performance optimizations and a more resilient SimConnect interface, this version delivers noticeably smoother operation, especially under high traffic loads. In practice, even persistent SimConnect issues appear to have been eliminated.
Overall, version 15.0 is not just an incremental update, it is a solid upgrade across realism, workflow, and stability.

Smoother than ever: PSXT 15.17 introduces frame-synchronized position resampling and guarded Hermite speed interpolation for take-off and landing rolls—delivering fluid movement without compromising PSXT’s rock-solid stability.
Version 16.5.0 represents a major step forward in the visual quality, natural motion and robustness of PSXT traffic. Aircraft behaviour has been refined throughout the complete movement cycle—from taxi and take-off to airborne flight, landing and rollout—while PSXT now responds more defensively to irregular live-traffic data.
Overall, Version 16.5.0 delivers PSXT’s most fluid, stable and convincing traffic movement to date.
