4. 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

5. 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

6. 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

7. 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

8. 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)

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

10. 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

11. 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)

12. 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

Level 2: Expectations - RASP
Level 3: ATM Component Functionality - RTSP
Level 4: System Requirements (e.g., RNP, RCP)
Level 5: Technologies (incl. standards, specifications)

13. 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
