SWIM Flight Data Publication Service (SFDPS)

SFDPS Overview

The System-Wide Information Management (SWIM) Flight Data Publication Service (SFDPS) provides en route flight data to National Airspace System (NAS) consumers. SFDPS allows consumers to receive real-time data for analytics, business processes, research, and other activities.

As shown in the graphic below, SFDPS provides Service-Oriented Architecture (SOA) message patterns for publishing data from the En Route Automation Modernization (ERAM) system. ERAM data is transmitted through the Host Air Traffic Management (ATM) Data Distribution System (HADDS), which is part of the En Route Data Distribution System (EDDS). These systems are located at each of the 20 Air Route Traffic Control Centers (ARTCCs) in the contiguous United States.

SFDPS Architecture

SFDPS receives data from HADDS in the Common Message Set (CMS) format, processes the messages into SWIM-compliant eXtensible Markup Language (XML) formats, and publishes the XML messages to the NAS Enterprise Messaging Service (NEMS) for distribution to authorized consumers, with external consumer access provided via the NAS Enterprise Security Gateway (NESG). SFDPS also provides this en route data on request to authorized consumers using the request-response (query) message pattern from an archive of data it maintains.

SFDPS provides consumers with access to National Airspace System (NAS) en route information by providing the following services:

  • En Route Flight Data Publication & Query
  • En Route Airspace Data Publication & Query
  • En Route General Message Publication & Query
  • En Route Operational Data Publication & Query

SFDPS provides additional functionality including transformation of data into Flight Information Exchange Model (FIXM) and Aeronautical Information Exchange Model (AIXM), flight-matching across centers, and Globally Unique Flight Identifier (GUFI) generation.
