FIXM Posts

Welcome to FIXM

The Flight Information Exchange Model (FIXM) is a data interchange format for sharing information about flights throughout their lifecycle. FIXM increases interoperability among all air traffic stakeholders by mediating interactions between Air Traffic Management systems, airspace users, transportation authorities, security and defense authorities, logistics and transportation providers, and many more.

FIXM as middleware

FIXM provides data-level interoperabiltiy among domains

FIXM provides common situational awareness, facilitates incident management, and enables the use of transportation and security data in new ways previously unavailable. FIXM simplifies the global exchange of data by providing a framework developed on international standards.

FIXM has a strong harmonization role. It provides a standardized way of communicating transportation and security data. It incorporates semantic context for the flight data it expresses, which makes it flexible: new data elements can be added to FIXM, and existing data elements can be discovered. FIXM is also modular, allowing a wide variety of system interactions while maintaining efficiency.

ATIEC 2014

2014 Air Transportation Information Exchange Conference

August 26th - August 29th
NOAA Science Center and Auditorium
Featuring AIXM, WXXM, and FIXM

NOAA Auditorium and Conference CenterThe United States Federal Aviation Administration (FAA) in partnership with Eurocontrol will host the 2014 Air Transportation Information Exchange Conference (ATIEC) on August 26-29, 2014 at the National Oceanic Atmospheric Administration Auditorium and Science Center in Silver Spring, MD.

The latest advancements on integration of information relevant for air traffic management in its broadest sense will be demonstrated and discussed. This will be done through presentations and working sessions on relevant information services, the definition of information domains, and the related exchange mechanisms.

Following the tradition of prior conferences, speakers from the international ATM community will be making major announcements regarding new versions and future evolutions of the now well-known exchange models:

  • Aeronautical Information Exchange Model (AIXM)
  • Weather Information Exchange Model (WXXM)
  • Flight Information Exchange Model (FIXM
