SWIM Terminal Data Distribution System (STDDS)

STDDS Overview

SWIM Terminal Data Distribution System (STDDS) converts legacy terminal data collected from airport towers and Terminal Radar Approach Control (TRACON) facilities into easily accessible information, which is published via the National Airspace System (NAS) Enterprise Messaging Service (NEMS).

STDDS publishes data from the following FAA airport and terminal systems:

  • ASDE-X - Airport Surface Detection Equipment – Model X
  • ASSC - Airport Surface Surveillance Capability
  • STARS - Standard Terminal Automation Replacement System
  • RVR - Runway Visual Range
  • EFSTS - Electronic Flight Strip Transfer System
  • TDLS - Tower Data Link Services

STDDS publishes data to NAS and non-NAS subscribers, via NEMS, in accordance with SWIM standards

STDDS Architecture

STDDS is installed at 38 TRACONS

  • Access to data from over 200 airports
  • Data from over 400 individual systems

STDDS News and Events

 

STARS TRACON Consolidations: SPI, PIA (9/10/2022)

On September 10-11, the STARS TRACONs at Springfield, IL (SPI) and Peoria, IL (PIA) will be consolidated into St Louis, MO (T75) TRACON.

This is a change to the STARS system; instead of being distinct STARS TRACONs, SPI and PIA will become remote towers within the T75 airspace, and their AIG data will become part of the T75 STARS/TAIS feed. It is possible that the STARS system will send radar data (track and flight plan messages) via both C90 and T75 for a short time.
