Real time live traffic for MSFS and Prepar3D

New: try my ChatGPT PSXT Tutor for all your questions, in your own language!

Pros!

Real-time live traffic injection, with about 30 seconds delay.

PSXT injects the exact real-time positions of live aircraft into your simulator.
PSXT is different from programs like BeyondATC, Say Intentions, FSHud, FSLTL Injector, and AIG Traffic. These use simulated traffic, PSXT uses real-time live traffic, just like what you see on FlightRadar24.

That means aircraft are exactly where they are in real life. They:

depart from and park at the real-life gates
use the actual runway in use
follow real airways, SIDs and STARs, or are vectored by real ATC
can reject take-offs, go around, divert, and keep real distances from each other
perform crosswind landings and take-offs realistically (crab landings)

Works with any AI aircraft models/liveries that are compatible with your simulator:

AIG, FSLTL, IVAO MTL, FS Traffic, ...
Fully animated: gear, flaps, spoilers, lights, reverse thrust, and spinning wheels in sync with sim speed

Best possible model/livery matching, based on tail number or airline + aircraft type:

Recognizes around 54000 current aircraft registrations, including airline, type, and whether it is a cargo plane
Has top-level model+livery matches for about 30500 aircraft, especially for AIG models, unmatched by any other traffic tool
Knows which AIG liveries are no longer in use, so it avoids showing them
Correctly assigns regional carrier liveries (like American Eagle) when using AIG, unique to PSXT
Also matches correct liveries for cargo operators like DHL, FedEx, and Amazon (when using AIG)
Optionally injects GA, fighter aircraft, and helicopters

Knows and/or learns on the fly where airlines park, with which aircraft, at what time of day and week

Parks static aircraft with the correct airline, model, and livery at the correct gate and time, no more empty airports!
Comes with about 11,400 learned airport files for MSFS (stock + 3rd party), and 6,600 for Prepar3D, all based on last weeks real traffic

Uses RealTraffics parked aircraft data for the past 24 hours

Live aircraft are visible in LittleNavMap and on your aircrafts TCAS
No flight plans needed
Works worldwide
Supports historic data too (with a RealTraffic Pro license, up to 2 weeks back)
Can support up to 100 fps
Runs as a separate process, using less than 0.5% CPU

PSXT is free to use, but a RealTraffic license is required for live data

Cons?

Injecting traffic reduces FPS. Still, 40+ FPS is possible, even on mid-range PCs
Aircraft follow live ATC, not programs like Pilot2ATC, but Pilot2ATC (and PF3) can detect PSXT aircraft and give alerts or holds
Live data is not included, it is delivered by a payware streaming service: RealTraffic by Inside Systems Pty Ltd
Live traffic coverage depends on your location. Some areas have great coverage, others not, but most major airports are well covered.

Choose real immersion, go for real-time live traffic!

To try it out, you can buy a 24-day standard license for RealTraffic, enjoy the realism, and judge for yourself.

MSFS users: If you already use AIG, FSLTL, or FS Traffic, setup is very simple, PSXT will detect and use your models/liveries automatically.

Download the standalone PSXT version (recommended)

Recommended because it is the easiest and the fastest implementation, working directly with the RealTraffic servers, you still have to buy a RealTraffic license but the Real Traffic application is not needed.

Use the free LittleNavMap program (MSFS2020 and MSFS2024) to see the traffic around you on a map.

download PSXT for MSFS 2020/2024, version 11.0.3

download PSXT_P3D for Prepar3D v5/v6, version 11.0.3

Download the PSXTraffic version for the RealTraffic app

This more complicated version is for users running two or more Simulators at the same time, or users that want to use the Radar screen of the RealTraffic application.

Is PSXT free?

Yes and no, my programs may be used free of charge. However, "free of charge" must not be confused with "completely free". It is copyrighted software, not free software. There are restrictions on distribution and use, read and acknowledge the EULA file when installing the software. A major restriction is that it is for non-commercial use only.

PSXT is free from advertisements. If you like my program, see below a link for donations.

This is entirely voluntary, there is no obligation whatsoever. Any donations will be put towards keeping the site hosting going and are received with my gratitude and thanks.

Just some example what people donating write:

And now for something completely different ...

My good old PSXseecon software for building a PSX B744 home cockpit

PSXseecon connects the Aerowinx Precision Simulator version 10 (PSX) with the SIOC software of Opencockpits.

It acts as a bridge between these two worlds, "talking" the Aerowinx Network Protocol over TCP/IP to PSX and "talking" the IOCP protocol over TCP/IP to the SIOC Server. Although both worlds offer a TCP/IP based interface, they speak different protocols, and they are both servers. PSXseecon acts as a client program to PSX and as a client program to SIOC and performs protocol translation.

2522 predefined SIOC variables representing 99% of the functionality of the PSX interface are available. These variables give access to almost all states and controls of the PSX. You can receive information about state changes in the 744 and you can set Buttons, Switches, levers, Throttles, Dials, what have you, in the 744.
