  3. Goals & Objectives • Weather Accident Prevention Goal:Develop enabling technologies to reduce weather-related accident causal factors by 25-50% and turbulence-related injuries by 25-50% by year 2007. • WxAP Objective Number 3: Develop turbulence prediction technologies, hazard metric methods, and mitigation procedures to enable a 25-50% reduction in turbulence-related injuries. • TPAWS Goal: Develop and augment knowledge of both the turbulence phenomena and the effects of turbulence on aircraft, and develop technologies to detect convective and clear air turbulence and mitigate the effects on aircraft passengers • Turbulence is the predominant weather threat for airborne tactical decision making relating to safety of cabin passengers and crew; also has significant operational costs impact

  5. Programmatic Boundaries • Budget Guidelines • TPAWS FY03-05 guidelines are intact • FY03-05 program support/infrastructure costs continue to increase resulting in less net research funds • FY02 was “bottom of v” profile, FY03 greater than FY02 • Personnel & Flight Assets Allocations • FY03 TPAWS personnel resources are “minimal critical mass” in total numbers, augmentation by new-hires • LaRC 757/Service Activity requirements from overall AvSP are maximized; continual trade-off process

  6. TPAWS FY03 Priority Areas • Systems-Oriented Process • Get the right turbulence information to/from the right aircraft with sufficient time for necessary decision making; focus on airborne tactical decisions • Develop a ConOps document and a Requirements document for Airborne Turbulence Information and Alerting System with inputs by stakeholders and end-users • Certification Methods & Tools • Turbulence Modeling and Simulation • Final formulation of turbulence safety hazard metric based upon aircraft dependent attributes • End-to-end analytical studies for scoring criteria/rules, validation boundaries

  7. TPAWS FY03 Priority Areas <cont’d> • Turbulence AutoPIREP Systems • 757/learjet flight experiments • Complete systems validation activities • Flight Deck Integration • Re-plan activities, clean sheet • End User/Customer Collaboration • One-to-one workshops; MOUs, MOAs for transitioning TPAWS items • TPAWS website for dissemination of technology status/flight results

  16. Background • Five Workshops to date; initiated by WxAP PM, Dec-00. • Workshop#3, TPAWS was chartered to lead this activity, and develop specific milestone and budget for FY02+ • “Tiger team” formulated and met, produced the Cert Methodology Chart, Sept-01; “6-box” chart • Two highly successful, collaborative workshops of NASA-FAA-Industry Turbulence Detection Certification Team • Feb-02 at NASA-LaRC, Workshop#4 • Sept-02 at FAA-Long Beach, Workshop#5
