ICAO Aviation System Block Upgrade Executive Briefing:

The Framework for Global Harmonization

Issued 10 June 2011

2ICAO ASBU Executive Briefing

The Challenge

• USD 120 billion will be spent on ATS transformation in next 10 years

• NextGen and SESAR account for large share of spending• Parallel investment initiatives also include:

– Latin America, Russia, Japan, and elsewhere • ATM Modernization is enormously complex task• As traffic levels in civil aviation continue to increase, Industry

stakeholders seek benefits of new initiatives


Why is Action Needed?

• Need to renovate ATM systems to:– Safely accommodate increase of air traffic demand– Respond to diversified needs of operators– Global environmental issue– Other issues inherent with current ANS

• ATM modernization programmes must harmonize to:– Provide greatest operational & performance benefits– Achieve seamless global air navigation into future


What are the Impediments?

• All programmes face risks & require mitigation strategies• Most significant risk is related to timing and mix of technical,

political, and infrastructure requirements • Set of risks exist independent of specific solution chosen:

– Non-homogeneous deployment across regions– Lack of synchronization of air & ground deployments– Future investment in existing ATM programmes by key stakeholders

not secured– Delays in standards development and approvals– AIM not implemented in global interoperable way– SWIM not implemented in correct form


ICAO’s Approach

• ICAO established programmatic, collaborative approach to develop set of ATM solutions

• Meet global needs for interoperable airspace that: – Takes advantage of current equipage– Establishes transition plan that provides key performance

improvements– Enables global interoperability

• ICAO launched Aviation System Global Block Upgrade initiative to facilitate:– Interoperability– Harmonization– Modernization of air transportation world-wide


What is an ASBU?

• Aviation System Block Upgrade (ASBU) designates set of improvements that can be implemented globally from defined point in time to enhance performance of ATM System

• A Block is made up of modules• Each module represents a specific, well-bounded improvement• A module can be grouping of several elements which can contain:

– Communications, navigation, surveillance components in aircraft– Communication system– Ground component of ATC automation

• or decision support tool for controllers

– etc. • Elements mutually make module comprehensive & cohesive


What is an ASBU? (Cont’d)

• ABSUs are suite or package of capabilities (called modules) where each has essential qualities of: – Clearly defined measurable operational improvement

• with appropriate metric to determine success– Necessary equipment and/or systems in aircraft and on

ground • along with operational approval or certification plan

– Standards & procedures• for airborne & ground systems

– Positive business case • over clearly defined period of time

Advantage of ICAO’s Approach

• Block Upgrades provide a series of measurable, operational performance improvements

• Organized into flexible & scalable building blocks

• Could be introduced as needed• Implemented as each

individual State and or Region determines feasible – based on individual needs &

level of readiness


What is the Basis for ASBUs?

• Foundation of blocks originates from existing, near term implementations and access to benefits that already exist

• Blocks are based on operational concepts extracted from:

• Intent is to apply key capabilities and performance improvements across other regional and local environments – with same level of performance and associated benefits worldwide

• Block upgrades will allow structured approach to meet needs of individual aviation communities worldwide– while considering associated business cases

• Block upgrades reflect recognition that all module solutions are not required in all airspaces


ASBUs & Performance Improvements

• ASBUs address 4 key Performance Improvement Areas: – Greener Airports– Globally Interoperable Systems and Data– Optimum Capacity and Flexible Flights– Efficient Flight Path

Timeframe

• Block 0: available to be deployed globally from 2013• Block 1: available to be deployed globally from 2018• Block 2: available to be deployed globally from 2023• Block 3: available to be deployed globally from 2028/beyond


Mitigating the Risks

• Deployment of ASBUs chosen to resolve many identified risks• Timing and sizing of Block Upgrades are in response to need for:

– Mature standards– Integrated air and ground solutions– Establishment of positive business cases for level of equipage and

infrastructure costs• Capabilities lacking specific maturity in content or described benefit

are purposefully placed in later Block Upgrades• ASBUs respond to issue of “non-homogeneous deployment across

regions”. – Block components are intended to interoperate seamlessly independent of

how they are implemented in neighboring States– To ensure procedures, training, policy, and other “infrastructure” are

consistent • Ensure safe transition to more capable airspace


Improvements for Phases of FlightExample: Block 0


A Team Effort


What’s Next?

• ASBUs initiative formalized at 12th Air Navigation Conference– In November 2012– As revision to ICAO Global Air Navigation Plan

• Global Air Navigation Industry Symposium (Sept 2011):– Allow States and industry partners to gain insight– Provide feedback– Ultimately commit to concept

• Initiative will influence ICAO’s future Standards development work programmes

• Block Upgrades and associated performance improvements will be realized by implementation actions in regions
