Measuring performance by meeting expectations Summary of day 2 Measuring performance by meeting expectations Capacity Cost-effectiveness Efficiency Environment Flexibility Global interoperability Access and equity Participation Predictability Safety Security

Performance Hierarchy Summary of day 2 Performance Hierarchy Level 1: Political and Socio-Economic Requirements Level 2: Expectations - RASP Level 3: ATM Component Functionality - RTSP Level 4: System Requirements (e.g., RNP, RCP) Level 5: Technologies (incl. standards, specifications) Initially defined in Global ATM Operational Concept Layers represent different views of the ATM system Allows tracing of performance impact Changes at lower levels impact next layer above Leads to expectations Helps understand and communicate performance case SPans2007

Summary of day 2 Performance Based Transition Approach STEP 1 STEP 2 What are the ATM community expectations? What is the current traffic and the expected traffic evolution? What are the current roadmaps and plans? What are the performance objectives? How to measure performance? What is the current and planned ATM performance? What are the current and anticipated performance gaps and their reasons? What are the available options for operational improvement? What is the Global ATM Operational Concept and associated system requirements? What selection and sequence of operational improvements addresses current and anticipated performance gaps? What are the resulting updates to current roadmaps and plans? What are the performance targets? 12 11 10 9 8 7 4 6 5 3 2 1
