On-Demand NAS Information

On-Demand National Airspace System Information will provide flight planners, air traffic controllers, air traffic managers, and flight crews with consistent and complete information related to changes in the airspace system, such as temporary flight restrictions, temporary availability of special use (military) airspace, equipment outages, and runway closures. The capabilities in this portfolio will be realized through access to and exchange of aeronautical and flight information using common data formatting and information exchange standards.


  • Environment

    Contributes to the protection of the environment by considering noise, emissions, and other environmental issues in the implementation and operation of the aviation system.

  • Flexibility

    Ensures the ability of all airspace users to dynamically modify flight trajectories and adjust departure and arrival times, thereby permitting them to take advantage of operational opportunities as they occur.

  • Safety

    Uniform safety standards along with risk and safety management practices should be applied systematically to the air transportation system. In implementing elements of the system, safety needs to be assessed against proper criteria, and according to appropriate and globally standardized safety management processes and practices.
