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

6
ATM Community Expectations

• Access and Equity
• Capacity
• Cost-effectiveness
• Efficiency
• Environment
• Flexibility
• Global Interoperability
• Participation by the ATM Community
• Predictability
• Safety
• Security

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

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)

Need for Consistent Framework
Global Interoperability Goal

• End-to-end performance
• Benchmarking
• Best Practices
• Accountability
• Consistent requirements
• Service Delivery

10
Performance Hierarchy

• 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

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
• 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)
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
Level 3 ATM Component Functionality - RTSP
Level 4 System Requirements (e.g., RNP, RCP)
Level 5 Technologies (incl. standards,
specifications)
14
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
