Air Transport eXchange (ATeX) is a high-speed, high-performance IP extranet that lets SITA customers exchange data with partners in the air transport and associated industries. It is based on SITA’s IP VPN.

Based on the TCP/IP suite of protocols, ATeX offers the capabilities of an “open” Internet service, but with the end-to-end management, flexibility and security required for corporate communications.

Airlines can use ATeX to access detailed technical information and diagrams from airframe or engine manufacturers in real time.

Access is instant and secure, reducing the time and expense involved in dissemination of this information on paper, microfilm or aperture cards.

ATeX architecture

• ATeX is an IP VPN community
• Open to any ATC member
• Charged per connection − dependent on geography and speed
• Any-to-any between ATeX members
• Separation from customer intranets − no ATeX-to-intranet traffic
