PSXT Live simulator traffic

MSFS 2020, MSFS 2024 and Prepar3D v5/v6

Real-world live traffic for serious flight simulation.

PSXT injects real-world aircraft into your simulator with accurate parking, realistic airport behaviour and detailed aircraft matching.

What PSXT does

Live aircraft, placed with real airport knowledge.

Unlike traditional AI traffic tools, PSXT does not rely on the simulator's own AI traffic engine. It runs as a separate process outside the simulator and places live aircraft using real-world traffic data, airport knowledge and matching logic.

  • Uses real-time traffic data from RealTraffic
  • Parks aircraft at their real live gates whenever possible
  • Matches aircraft, airlines and liveries using your installed model sets
  • Can show realistic live and parked traffic at airports
  • Designed for users who value realism, control and predictable behaviour

MSFS users: if you already use AIG, FSLTL, IVAO MTL or FS Traffic, setup is straightforward. PSXT automatically detects and uses your installed models and liveries.

Is PSXT free?

PSXT itself can be used free of charge for non-commercial use.

For real-time traffic you need a separate RealTraffic license.

Why PSXT?

Choose realism. Choose real-time live traffic.

Real-world movement

  • Real-time live traffic injection, typically with about 30 seconds delay
  • Exact real-world positions of aircraft in your simulator
  • Real runway use, airways, SIDs, STARs and ATC vectoring
  • Reject take-offs, go arounds, diversions and crosswind landings

Your installed models

  • AIG, FSLTL, IVAO MTL, FS Traffic and others
  • Animated gear, flaps, spoilers, lights, reverse thrust and wheels
  • High-quality model and livery matches for about 30,500 AIG aircraft
  • Optional support for GA, military aircraft and helicopters

Airport intelligence

  • Learns where airlines park, with which aircraft and at what time
  • Places parked aircraft at correct gates, avoiding empty airports
  • Includes about 18,200 MSFS 2020, 18,500 MSFS 2024 and 15,800 Prepar3D airport files
  • Uses RealTraffic parked aircraft data for the past 24 hours

More advantages

  • Recognizes about 68,700 real aircraft registrations
  • Avoids outdated liveries automatically
  • Supports regional carriers and correct cargo liveries
  • Visible in LittleNavMap and on TCAS
  • No flight plans required, worldwide coverage
  • Supports historic data with RealTraffic Pro
  • Runs as a separate process with minimal CPU usage

Good to know

  • Injecting traffic reduces FPS, although good performance is still possible on mid-range systems
  • Aircraft follow real ATC, not external ATC programs, although tools like Pilot2ATC can still interact
  • Live data is provided by a separate paid service: RealTraffic
  • Coverage depends on region; major airports are generally well covered

User feedback

What users say

"This is by far the most realistic traffic I have ever seen."
"Finally correct gate parking and real-world behaviour."
"PSXT completely changed how my simulator feels at busy airports."

PSXseecon 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 the IOCP protocol over TCP/IP to the SIOC Server. 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. Everything you need to build a cockpit is there, including a nice example at Facebook.
