Item 7b_Supp Federal Aviation An Update: Administration Greener Skies Over Seattle Thinking Globally Acting Locally To: Port of Seattle Commissioners David C. Suomi Acting Regional Administrator Northwest Mountain Region February 28, 2012 What is NextGen? NextGen represents the transformation of our national airspace system, making it flexible and sustainable It is not a single program or procedure but a comprehensive initiative that integrates new and existing technologies, procedures and policies Greener Skies Project Federal Aviation 2 February 28, 2012 Administration Why do we need NextGen? 5,000 airplanes in air at any time 1 billion passengers per year More than 10 Million jobs More than 5% of GDP Greener Skies Project Federal Aviation 3 February 28, 2012 Administration BroadlyWhat do we need? An airspace system that will: Ease congestion and offer increased capacity to match demand while ensuring safety Prepare for the new types of aircraft UAS and commercial spacecraft, for example Reduce impact on the environment without impacting aviation's contribution to our economy Greener Skies Project Federal Aviation 4 February 28, 2012 Administration Greener Skies Project Initiative 1 (i1) STARs and RNP/RNAV approaches Flight Simulation Trial Results Environmental Assessment Initiative 2 (i2) Research Contract "RNP Established" Concurrent Approaches SEA / BFI Perhaps more??? Project Timeline/Milestones Greener Skies Project Federal Aviation 5 February 28, 2012 Administration Required Navigation Performance (RNP) Approaches Consistent, controlled approaches Substantially shortened flight path length (green vs. blue) Noise exposure reductions with accurate routings over less noise sensitive areas (e.g. Elliott Bay) Reduced greenhouse emissions Minimized operational costs Greener Skies Project Federal Aviation 6 February 28, 2012 Administration Greener Skies Project Federal Aviation 7 February 28, 2012 Administration OPD STAR that connects to an RNP AR through Elliott Bay Greener Skies Project Federal Aviation 8 February 28, 2012 Administration Seattle Greener Skies Goals and Objectives Reduce track mileage to minimum possible distance Optimized Profile Descents (No level-offs, flown at idle thrust from cruise until established on final) Absorb delays at cruise altitude Reduce/eliminate low altitude radar vectoring Reduce fuel burn Identify and implement the tools, technologies and practices that enable achievement of these goals Greener Skies Project Federal Aviation 10 February 28, 2012 Administration Understanding Optimized Profile Descent (OPD) Operations Optimized Profile Descent Operations: Are enabled by airspace design, procedure design, and ATC facilitation Allow aircraft to descend continuously Employ minimum engine thrust, in a low drag configuration Objective: Usable by 85% of aircraft, 85% of the time Greener Skies Project Federal Aviation 11 February 28, 2012 Administration Optimum OPD An optimum OPD starts from the top of descent while: Reducing - ATC/Pilot communication - segments of level flight - noise - fuel burn Increasing - emissions - predictability to ATC/Pilots - flight stability Greener Skies Project Federal Aviation 12 February 28, 2012 Administration Traditional Approach High noise levels Inefficient High CO emissions Freq Communications Greener Skies Project Federal Aviation 13 February 28, 2012 Administration Optimized Profile Descent Approach Reduced noise Highly efficient Reduced emissions Reduced Communication Greener Skies Project Federal Aviation 14 February 28, 2012 Administration Actual CDO Operation Flight tracks before OPD Flight tracks after OPD Greener Skies Project Federal Aviation 15 February 28, 2012 Administration Importance of an Idle Descent Idle Descent 640 lbs/hr/engine 1280 lbs/hr 3.2 gal/min Greener Skies Project Federal Aviation 16 February 28, 2012 Administration Level-offs Use 4-5 Times More Fuel Than Idle Descent! x 3.7= Level, 210 kt, flaps up Idle Descent x 4.0= Level, 180 kt, flaps 5 x 4.4= Level, 170 kt flaps 10 x 5.5= Greener Skies Project Level, 160 kt, flaps 15 Federal Aviation 17 February 28, 2012 Administration Quantifiable Annual Benefits 4,800 less flight hours $20.4M savings 2.9M gallons less fuel used $7.3M savings 30,500 metric tons less CO2 emissions equivalent to removing 5,600 cars annually from the Seattle region Greener Skies Project Federal Aviation 18 February 28, 2012 Administration Greener Skies Project Federal Aviation 19 February 28, 2012 Administration Why Seattle? A clear, decisive early "win" with NextGen anywhere will incentivize airports and airlines to move forward with embracing the transition. Any carrier successfully using OPDs and RNPs in a given market will have a competitive tool that other carriers will have to embrace to remain competitive. Seattle represents a fit, willing and able local lead carrier (Alaska/Horizon), and a committed airport operator (Port of Seattle). Seattle represents complex, but not saturated, airspace, thus a good environment to demonstrate the wide range of NextGen capabilities. Greener Skies Project Federal Aviation 20 February 28, 2012 Administration Why Seattle? (con't) Seattle represents extremely high existing equipage of operators, over 80%, thus assuring an easier transition with remaining legacy equipment operators. Seattle has intense local, Congressional, and Administrator support. (Sen Murray, Chair Senate Transportation Appropriations, Sen Cantwell, Chair, Aviation Operations) Excellent facility Bargaining Unit rapport, both between TRACON and ARTCC, and between facilities and procedure designers. Seattle represents the highest possibility of success in a single market, and thus to "bootstrap" Next Gen in a wider venue. Greener Skies Project Federal Aviation 21 February 28, 2012 Administration Benefits More efficient use of airspace and arrival route placement More consistent flight paths and stabilized approach paths Reduction in both pilot and controller workload Reduction in the number of required radio transmissions Cost savings and environmental benefits through reduced fuel burn Reduction of controlled flight into terrain (CFIT) incidents Noise sensitive operations Greener Skies Project Federal Aviation 22 22 February 28, 2012 Administration Federal Aviation Administration Thank You Greener Skies Project Federal Aviation 23 February 28, 2012 Administration

PDF files are created with text and images are placed at an exact position on a page of a fixed size.
Web pages are fluid in nature, and the exact positioning of PDF text creates presentation problems.
PDFs that are full page graphics, or scanned pages are generally unable to be made accessible, In these cases, viewing whatever plain text could be extracted is the only alternative.
