OAT Enterprise “ 3 Pillars” • Global Civil Aviation – Five stretch goals • Revolutionary Technology Leaps – Three stretch goals • Access to Space – Two stretch goals J. V. Lebacqz NASA
Five Goals for Global Civil Aviation Reduce the aircraft accident rate by a factor of five within 10 years, and by a factor of 10 within 20 years. While maintaining safety, triple the aviation system throughput, in all weather conditions, within 10 years Reduce the perceived noise levels of future aircraft by a factor of 2 within 10 years, and by 4 within 20 years Reduce emissions of future aircraft by a factor of 3 within 10 years, and by 5 within 20 years Reduce the cost of air travel by 25% within 10 years, and by 50% within 20 years J. V. Lebacqz NASA
Delay Growth and Mitigation System efficiency as measured by average delay in NAS Predicted delay growth due to 2. 3% annualized growth in air traffic (FAA, NASA, Boeing consistent) Airline Schedule Integrity Lost if Average Delay > 4 Mins 2007 Goal “Free Flight - Preserving Airline Opportunity”, Capt. Russell G. Chew, American Airlines, September 22, 1997 J. V. Lebacqz NASA
Benefits: Goal 4: Aviation System Throughput • Enable significant improvements to critical transportation infrastructure • Assure safe, reduced delay flight as air traffic density increases • Improve mobility for public • Improve air-traveler’s time productivity While maintaining safety, triple the Aviation System throughput, in all weather conditions, within 10 years CHALLENGES 1997 OUTCOMES 2000 2005 2010 2015 2007 Safe, efficient air traffic management with allweather operation beyond current clearweather capacity FAA NAS Architecture Terminal Area Productivity Phase III Extended Operations Systems Technology for Advanced Operational Concepts Advanced Air Transportation Technologies Aviation Safety Program Phase II Integration of Intelligent Aviation Systems Information Technology & Aerospace Operation Systems Aircraft Configuration Short-Haul Civil Tilt Rotor 2 Industry /FAA Industry/Do.
