  3. 1st Workshop Objectives • Understand degree of “cockpit effect” from a proposed forward looking, airborne • turbulence sensing system both near term and in the future. • Understand how we can build upon “Windshear Radar Program” model to • forward looking, airborne turbulence sensor system effort (i.e. FAA/NASA- • Airline-Industry relationship) • Better understand the major certification and operational issues. • Understand Industry time line towards certification • Better understand NASA-FAA-Industry roles and responsibilities in the • certification process • Define next Workshop (goals, objectives, time and place) • Establish case/framework for NASA-Industry Agreement

  4. Key Points From Workshop #1 • Understanding of Airline/Pilot/market drivers critical to defining functional and operational requirements of a forward-looking turbulence sensor system • Development of forward-looking turbulence sensor system certification and government-industry-airline relationship model based on Predictive Windshear process will improve probability of success • Drivers for turbulence detection system are different than for Predictive Windshear • Aggressive implementation schedules need to be supported by well-defined requirements, hazard/threat definition, standards, and certification methodology • The degree of cockpit effect has a major affect on certification requirements and therefore must be fully defined and understood

  5. Key Points From Workshop #1 (cont.) • False-alarms will most likely be less tolerated for turbulence sensors than they are for predictive windshear; need to guard against pilot rejection of initial products • Phased approach to sensor implementation may enable collection of in-service data for use in requirements development; legal implications may discourage participation • Sensor requirements should be driven by hazard definition, operational factors and functional requirements, rather than sensor capabilities driving the process

  6. Draft Master Schedule Phase I - Enhance current turbulence radar capabilities (no cockpit effect) 1/01 1/02 1/03 1/04 Phase II - Significantly enhance or new turbulence detection capabilities (IR inferencing; Lidar; full cockpit effect; information combined from multiple sources)
