Weather Product Development

Tom Fahey, Manager of Meteorology at Northwest Airlines, discusses innovative weather product development strategies aimed at enhancing safety, efficiency, and reducing costs. The presentation highlights the challenges faced, particularly in turbulence encounter costs, and outlines implemented initiatives such as the Turbulence Plot System (TPS) and Convective Wind Shear Alerts. Fahey emphasizes the importance of real-time quality control and user-driven specifications to ensure effective and adaptable weather products, ultimately supporting safe airline operations and improving pilots' operational decision-making.

  1. Weather Product Development Tom Fahey Manager - Meteorology Northwest Airlines A Northwest Airlines Perspective

  2. Shared Goals Wx Product Development • Improved Safety • Increased Efficiency • Reduced Costs The Challenge: No two Airlines Define them the same

  3. Turbulence Encounter Costs • Costs * • Minor Injury - $38 K • Serious Injury - $518 K • Death - $2.7 Million • * Source: U.S. Federal Government Office of Management and Budget (OMB)

  4. NWA’s Implemented Initiatives Wx Product Development • Turbulence Plot System (TPS) • Convective Wind Shear Alerts • Strategic Planning Team (SPT) • Collaborative Convective Fcst Prod (CCFP)

  5. Convective Wind Shear Alerts • Source • FAA TWIP System • Distribution Methods • Pilot Request • Unsolicited Uplink (Send/Cancel Msgs) Pt: Addressed Varied Operating Philosophies

  6. TWIP Airports

  7. Bogus Alerts Convective Wind Shear Alerts • NWA Study Jan-May 2000 • 72 Bogus Alerts - No Storms within 15nm (25 ranged 50-95kts) (22 ranged 30-50 kts due gusty winds) • 100’s Bogus Alerts - No Storms within 15nm (100’s ranged 20-25kts due gusty winds)

  8. Support, Resources and Gaps Convective Wind Shear Alerts • Real time Quality Control • Conceptual Models • Convection Induced Shear • “No Storms within 15nm” Induced Shear • Training

  9. CCFP Wx Product Development • Excellent Example • “Rapid Development” • “User Driven”

  10. CCFP Rapid Development • 1997 • 1998 • 1999 • 2000

  11. CCFP Support, Resourcesand Gaps • NWA Role • Industry Perception • AWC Issues • Meteorologist Role • CWSU’s • Airline Meteorology Offices • FAA and SPT Role

  12. Summary Wx Product Development • Design Requirement • Adaptable to varied users • Recipe for Success • User Driven Specs • Potential for Failure • Lack of on going quality control • No Conceptual Model Updating • No Recurrent Training
