The Global ATM Operational Concept Endorsed by 35th Session of the Assembly Vision: Globally interoperable All users & flight phases Safe, economic, environmental & secure ATM user expectations are drivers for change, requiring: Safety case Business case Foundation for ATM System Requirements

Global ATM Requirements The Global ATM Operational Concept envisions a system that is service oriented, performance driven and predicated on the guiding principles described in the OCD (Global Air Traffic Management Operational Concept, Doc 9854). To fulfill this vision, the ATM system shall: a. Ensure that performance forms the basis for all ATM system development; b. Treat performance as a whole, that is, considering all the ATM community expectations and their relationships; Performance-based ATM is central What does this mean? Justify changes (operational improvements) to the ATM system with their performance impact Post-implementation monitoring Balance the multiple aspects of performance Guided by community expectations

ATM Community Expectations Key Performance Areas Access and Equity Capacity Cost-effectiveness Efficiency Environment Flexibility Global Interoperability Participation by the ATM Community Predictability Safety Security Objectives Indicators

Overview of Performance Process Expectations lead to targets Current performance is measured Future performance is estimated from forecasts Performance gaps are addressed via additional operational improvements Performance is monitored Plan is adjusted  More detail in subsequent talk Expectations Objectives & Indicators Targets Current performance Future performance Address Gaps Monitor

Level of Consistency Variations in expectations & actual performance Across time Location ATM community member System is tailored to best meet needs of individual locations at specific times Harmonized on: Consistent definitions Measurement, data, and estimation Consistent performance approach It is critical that the metrics be applied uniformly across the total system, i.e. that in a series of linked systems (regions, homogenous areas, etc.) they will be the same, while the actual required level of performance may be variable. (From Doc. 9854)

Need for Consistent Framework Global Interoperability Goal End-to-end performance Benchmarking Best Practices Accountability Consistent requirements Service Delivery

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

Level 2 - Expectations Expectations = 11 ATM Community Expectations Outcomes of the ATM system Required ATM System Performance (RASP) The collection of targets within all 11 KPA Function of time as targets evolve Actual ATM System Performance Measured through indicators within 11 KPA 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)

Level 3 – ATM Component Functionality Internal performance of ATM system What functions/services does the ATM System perform? How do these deliver the outcome? Performance-case Service-level impact Traceable RTSP 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)

Levels 4/5 – System Requirements & Technology Level 1: Political and Socio-Economic Requirements Decomposition of ATM System What system performance is required to deliver a level of service? Technologies Systems implement technology Focus on shared technology Must include functionality Level 2: Expectations - RASP Level 3: ATM Component Functionality - RTSP Level 4: System Requirements (e.g., RNP, RCP) Level 5: Technologies (incl. standards, specifications)

Putting it Together Provides a consistent structure based on type of improvement Trace improvements up the hierarchy Tool for accountability Post-implementation measurement across levels Level 1 Level 2 Level 3 Level 4 Level 5 People Procedures Infrastructure System Design Technology
