EAO Strategy Evaluation Method Strategy Impact Characterization Direct NAS Effects (ACES, LMInet, MLM) Multi-year Consumer, Carrier Ramifications (NAS Strategy Simulator, DoC) Strategy Impact (Metrics) Safety, Environmental (NIRS, INM) Security, Economic Impacts (GRA AMMS & NACBA, Volpe) Strategy Development Decisions Strategy Evaluation Existing Data (e.g. ETMS Schedules) Define Future Schedule and Conditions (AvDemand) Validation

Overview of LMINET Fast-time NAS-wide queuing model Uses a flight schedule covering 600+ commercial airports (derived from OAG), GA airports (derived from NPIAS), plus international airports (derived from OAG) Calculates delays at 102 airports and en route capacity constraints at 995 sectors; determined by the flight schedule, flight trajectories, airport runway configuration, and airport weather conditions

Futures Scenarios Evaluation Process 1.Assumptions of inputs 2.Develop Scenario modeling assumptions 3.Generate output performance metrics 4.Review results and assess any adjustments that need to be made to ensure modeled scenario is 1.realistic and 2.reflects futures working group’s intentions. 5.Iterate through steps 1-4 until step 4 is satisfied

Assumptions for Futures Scenario Set of futures. For each case –Model the implications to show what it means for the NAS Develop model assumptions and parameters to reflect characteristics of the scenario –Passenger and cargo demand scenario –Fleet mix and aircraft types –Business models Level of international flights Size of aircraft Growth Travel time Scheduling impacts –Workload levels within the NAS –Environment and weather

Futures Scenario Asia’s Century U.S. has won the war on terror –but lost its economic and technological leadership Slow economic growth Declining industrial and transportation infrastructure Domestic vacation travel and leisure is greatly reduced

Flights 1.4-3X Passengers X Future Environment and Demand Baseline Values 2004 Baseline Current Flight Schedule Current Capacities 1X ~3X Shift in passengers per flight (e.g., A380, reverse RJ trend, higher load factor) 20?? ~2X Biz shift Smaller aircraft, more airports Note: Not to scale Terminal Area Forecast (TAF) Growth Projection 2014 and later Baseline analysis will use OEP & FACT Capacities TAF Growth Ratios, Higher Rate TAF Growth Ratios, Lower Rate 2014 Biz shift 2% shift to micro jets Increase of over 10 passengers per flight

CAPACITY: Future Airspace Overload ENVIRONMENT: Increased Noise Impact Unconstrained Capacity Constrained COST: Lost Airline Profit Major capacity increases using existing paradigm lead to significant environmental and safety issues Shortfalls in capacity lead to significant economic consequences. SAFETY: Fatal Accident Rate Must Decrease to Maintain Current Safety Record X Example Performance Analyses

EAD Metrics Efficiency Safety Environment Accidents # of Operations Emissions Metrics capture the potential benefits of future strategies for key ATS attributes such as Efficiency, Safety, Environment, Security, etc. The common denominator for all EAD metrics is the forecast total number of aircraft operations. The use of a common metric allows evaluation of the benefit tradeoffs across multiple ATS attributes. Delays Current System Future Concept ATS AttributesMetrics
