## Workshop ITheme:  Define the Problem

- Workshop ITheme:  Define the Problem

**Noise Breakout Group:**
**Goals Unclear Vis-a-Vis Perceived Problem**
**Metrics & Models Inadequate**
**Plan Needs to Balance Near & Far-Term Research & Basic & Focused Research**
**No Strategy for Other Deployment Issues (Cost, Safety, etc.) for Success**
**Emissions Breakout Group:**
**Plan is Needed to Balance Evolutionary & Revolutionary Research**
**System Approach Needed to Maximize the Benefits of New Technology, Operational Improvements & Procedural Changes**
**Improve Methods to Evaluate Trade-offs Between Emission Strategies, eg., NOx vs. CO2**
**Need Improved Understanding of Ozone Chemistry**

## Workshop IIIFinal 4 Questions

- Workshop IIIFinal 4 Questions

**Goals:  **
**Will the Attainment of the Goals Satisfy Your Environmental Concerns?**
**Investment Strategy:  **
**Does the NASA Research & Development Strategy Appear to be Appropriate?**
**Roadmaps:**
**Have the Roadmaps Properly Leveraged On-Going Programs & Reached an Appropriate Balance Between Near-Term & Far-Term Goals?**
**What Programs Need to be Started as Soon as Possible?**
**Moving Forward:**
**Would a Continuing Communication with NASA Regarding These Issues & Programs be of Value to Your Organization?**
**What Role Would You be Willing to Play in Furthering the Pursuit of These Research Objectives?**

## Feedback - Goals

- Will the Attainment of the Goals Satisfy Your Environmental Concerns?
- Answers Varied From Qualified Yes to a Qualified No.  Key Points Included:
**Three Pillar Goals are Technology Goals...Public Concerns are Levels of Emissions & Noise from the Fleet of Operating Aircraft**
**Other Criteria (Safety, Affordability, etc.) Must be Part of Any Solution**
**Appropriateness of the Noise & Emissions Goals are Questioned (e.g., the Use of a 20-dB Reduction for Light Aircraft)**

## Feedback - Strategy

- Does the NASA Strategy Appear to be Appropriate?
- Generally, the Strategy is Appropriate, as Far as it Goes, but...
**Address Other Types of Aircraft**
**Funding for Development of Promising Technologies Through Technology Readiness Level 6**
**Stronger Research Coordination...NASA & Other Agencies**
**Strategy Extended Beyond Research & Technology for Overall Success (e.g., Acceptance, certification, regulation, operations, etc. )**

## Feedback - Roadmaps

**Have the Roadmaps Reached Appropriate Near & Far-Term Balance? Identify Technologies to be Pursued ASAP?**
**Near-Term Solutions -  Focus on Improved Efficiency, Better Models and Systems Studies**
**Interim Action -  Pursue Operational Improvements (e.g., CNS/ATM) & AST Developments (via Retrofit)**
**Far-Term NASA Role is Crucial - “NASA Has a Critical Role to Play in a Basic R&D Program & in ‘Thinking Outside the Box!’” (Zero Emission Aircraft)**
**Do Not Pursue Alternative Carbon-Based Fuels - All the Problems Associated with a New Fuel Infrastructure & Few Benefits**

## Feedback - Roadmaps (Continued)
