The Future

• Significant growth to 2025– Global passengers, 4.2 to 9 billion– Aircraft Movements to 173% – Higher regional growth

• Advanced avionics• Longer range flights

– More aircraft classes– Extended aircraft range

• Global aircraft resale market

Accommodate growth in a seamless, globally interoperable manner

The Challenge

• Disparate systems• Rigid structures• Limited collaboration• Not best use of scarce

resources• Limited information exchange• Advanced avionics

capabilities underutilized• Long lead times for system

improvement

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



March 27, 2007

Global ATM Requirements

• 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

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;



March 27, 2007

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

Community• Predictability• Safety• Security

Key Performance Areas

Objectives



March 27, 2007

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

March 27, 2007

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)



March 27, 2007

Need for Consistent Framework

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

Global Interoperability Goal



March 27, 2007

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

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)



March 27, 2007

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








March 27, 2007

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








March 27, 2007

Levels 4/5 – System Requirements & Technology

• 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








March 27, 2007

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
