2. Discussion Topics NASA AND FAA ROLES - TECHNOLOGY RESEARCH & DEVELOPMENT AIRLINES SUPPORT - ENVIRONMENT COMPATIBILITY BUDGET PROBLEMS-NEED TO RESOLVE; FIND BEST SOLUTIONS PRIORITY PROJECTS - NASA & FAA U.S. ECONOMY - TIED TO GLOBAL ECONOMY AIRLINES INDUSTRY-ATA EMISSIONS TASK FORCE PURCHASE LATEST TECHNOLOGY AIRCRAFT

3. NASA & FAA Partnership NASA FAA PARTNERSHIP - MOA, OCTOBER, 1998 GOALS ARE TO PURSUE –SAFETY IMPROVEMENTS –AIRSPACE SYSTEM EFFICIENCY –AIRCRAFT ENVIRONMENTAL CONCERNS

4. Support Environmental Compatibility REDUCTION OF AVIATION ENVIRONMENTAL EFFECTS - NATIONAL AND INTERNATIONAL –ICAO Process –NASA Research –FAA RE&D INCREASES IN NASA & FAA RE&D ENVIRONMENTAL BUDGETS U.S. GOVERNMENT PROVIDING A SAFE ENVIRONMENT FOR ALL THE PEOPLE –Space vs Environment

5. Long Term Commitments STATEMENTS FROM 1995 NATIONAL SCIENCE & TECHNOLOGY COUNCIL* –ENSURE LONG-TERM ENVIRONMENTAL COMPATIBILITY OF THE AVIATION SYSTEM –PAST RESEARCH INVESTMENT IN TECHNOLOGIES TO REDUCE ENGINE NOISE & EMISSIONS ARE PAYING DIVIDENDS TODAY –ENVIRONMENTAL ISSUES ARE LIKELY TO IMPOSE FUNDAMENTAL LIMITATION ON THE AIR TRANSPORT GROWTH IN THE 21ST CENTURY MUST REGAIN & MAINTAIN OUR GLOBAL LEADERSHIP ROLE –COMPETITIVE IN GLOBAL ECONOMY –E.U. Spends US? * From statement by FAA RE&D Subcommittee to Advisory Committee, 1999

6. NASA Priority Projects HSR - HIGH SPEED TRANSPORT –LOW ALTITUDE - SUB SONIC LEVEL –SUPPORT ICAO REQUIREMENTS EMISSIONS RESEARCH –NO NEED FOR SUPER SONIC TRANSPORT (SST) AST - ADVANCED SUBSONIC TECHNOLOGY –NOISE - ENGINES AND WINGS UEET - ULTRA EFFICIENT ENGINE TECHNOLOGY –EMISSIONS –FUEL CONSUMPTION –TRL 6 –AEROSOL & 2.5 PARTICULATE MATTER DATA BASE

7. Airline Industry Contributions ATA Emissions Task Force-Partnerships EPA, FAA, States, Engine Manufacturers, Airport, NGO’s Identify Methods to Reduce National Emissions Airline Industry is Funding Purchase New Latest Technology Aircraft- Phase Out Old –Must be Economically Feasible –Must be Cost Effective

8. Possible Solutions Ask Congress for More Money-National Policy Nation’s Aviation Trust Fund –$6.8 Billion Surplus Military-DoD Consult Other Research Activities-EU Industry-Supply Test Engines Other Partnerships-DoD, EPA, State/Local Government

9. NASA Customers Agenda –Airframers-Development/Production –Engine Manufacturers-Development/ Production –Airports-End Users –NGOs-End Users Others –Military-End Users –ICAO-Recommend Standards –EPA-Set Standards –FAA-Enforce Standards

10. New & Old Aircraft- Economic Feasibility New Aircraft Purchased-1999 –45 New Aircraft –New 777 & 737 Fleets CAEP 4 Missions EU Proposed 9-14 dB Noise Reduction Fuel Efficient Phase Out Old 727 & DC-10 Fleets Aircraft Engine Costs-1999 –777 Aircraft $140 Million Each Spare Engine$ 14 Million Each –737 Aircraft$ 48 Million Each Spare Engine$ 7 Million Each
