NextGen—Why?

WMO

  • Weather accounts for 70% of all air traffic delays within the U.S. National Airspace System (NAS)

    • The Federal Aviation Administration (FAA) has determined two thirds of this is preventable with better weather information

  • "A key finding, based on an analysis of several 2005-2006 convective events, is that as much as two-thirds of the weather related delay is potentially avoidable." -Research, Engineering and Development Advisory Committee; Report of the Weather-ATM Integration Working Group; Oct3, 2007

NextGen—Why?

WMO

  • “The total cost of domestic air traffic delays to the U.S. economy was as much as $41 billion for 2007.”

    • Air-traffic delays raised airlines' operating costs by $19 billion.

    • Delays cost passengers time worth up to $12 billion.

    • Indirect costs of delay to other industries added roughly $10 billion to the total burden.

    • Your Flight Has Been Delayed Again; Congressional Joint Economic Committee; May 2008

NextGen—How?

WMO

  • Improvements to the U.S. air transportation system will be achieved by applying:

    • Space-based navigation and integrated surveillance

    • Digital communications

    • Layered adaptive security

    • Weather integrated into decision-making

    • Advanced automation of Air Traffic Management

    • Net-centric information access for operations

Single Authoritative Source

WMO

  • The 4-D Weather Single Authoritative Source (SAS):

    • Is only a portion of the 4-D Weather Database

    • Provides a common weather picture for National Air Space (NAS) participants (Airlines, Military, FAA, etc.)

    • Is the basis for all aviation decisions by Air Traffic Management (ATM) in the FAA

    • Is formed by merger of model data, automated gridded algorithms, climatology and observational data, and meteorologist input/data manipulation to ensure consistency and accuracy

  • FAA and NWS collaboratively determine contents of SAS subject to FAA air traffic management needs

NextGen Weather Transformation

  • Forecast Process

    • Forecaster input to weather information to add value

      • Meteorologist in/over the loop

  • Global Harmonization

    • Discussion and collaboration with international community

    Summary

    WMO

    • U.S. NextGen is a Congressionally-mandated initiative to modernize the U.S. Air Transportation System in order to increase capacity and reliability; improve safety and security; and minimize the environmental impact of aviation

    • Weather integration into Air Traffic Management (ATM) is a key component to the NextGen

    • The 4-Dimensional Weather Database will be a virtual repository for weather information needed for pilots and air traffic managers to be aware of how the weather will impact airport and flight operations

    • The Single Authoritative Source (SAS), a subset of weather information in the 4-D weather database, will provide a consistent weather picture for all official air traffic management decisions
