Air Traffic Management (ATM) System

As the demand for air transportation increases, the capacity of the current U.S. ATM system will eventually be stressed to its limits. New technologies in communication, navigation, and surveillance (CNS), along with new decision-support systems and an evolutionary development of the ATM system architecture, can extend the capacity of the current system for several years. NASA has developed a new method and system, based on Extensible Markup Language (XML), that relates to control of aircraft traffic through specification of trajectory coordinates.
