2. Overview WMO • NextGen—Why? • NextGen—How? • NextGen Weather • Summary NextGen Update 2

3. 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 Update 3

4. 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 Update 4

6. 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 NextGen Update 6

10. 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 Update 10

11. NextGen Weather Transformation WMO NextGen Update 11

12. 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

13. 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 NextGen Update 12
