International Civil Aviation Organization ICAO Aviation System Block Upgrade Executive Briefing: The Framework for Global Harmonization Issued 10 June 2011

The Challenge • USD 120 billion will be spent on ATS transformation in next 10 years • Next. Gen 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 ICAO ASBU Executive Briefing 2

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 ICAO ASBU Executive Briefing 3

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 ASBU Executive Briefing 4

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 ICAO ASBU Executive Briefing 5

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 ICAO ASBU Executive Briefing 6

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 ICAO ASBU Executive Briefing 7

What is an ‘Aviation System Block Upgrade’ ? ICAO ASBU Executive Briefing 8

It’s been done before - PBN Operational Improvement • Fewer Runway Excursions • Less Noise & Emissions • Fuel Savings • Lower Pilot workload • Lower ATC Workload Performance Monitoring by PIRGs/States • Metrics Positive Business Case • Minimum investment; using existing airborne technology • Rollout (Formulation of business case by States) Necessary Procedures Air & Ground • Annex 2, 10 & 11 (2008) • Annex 14 & 15 (2009) • Annex 4 & 6 (2010) • Annex 3 (2012) • Procedures Ops Vol. 1 & 2 (2008+2010+2012) • Procedures ATM (2010+2012) • Procedures ABC (2010) • PBN Manual (2008+2011) • RNP AR Manual (2009) • Continuous Descent Operations (2010) • Continuous Climb Operations (2012) • Quality Assurance Manual (2010) • Airspace Design Handbook (2011) • Rollout (planning& implementation by PIRGs/States) Regulatory Approval Plan Air & Ground • Ops Approval Handbook (2011) • PBN Model Regulations (2011) • Rollout (planning& implementation by PIRGs/States) ICAO ASBU Executive Briefing Necessary Technology Air & Ground • Annex 10 (2008) • GNSS Manual (2011) • Rollout (planning & implementation by PIRGs/States) Global Demonstrations and/or Trials • Oceanic – RNP 4; Pacific • Continental – RNAV 5; S. America • RNAV 10; Red Carpet Africa • Challenging Approaches • Lhasa, Queenstown • Rollout (planning & implementation by PIRGs/States) 9

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 ICAO ASBU Executive Briefing 10

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 ICAO ASBU Executive Briefing 11

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 ICAO ASBU Executive Briefing 12

Improvement Areas, Blocks & Modules Performance Improvement Areas Block 0 (2013) Block 1 (2018) Block 2 (2023) Block 3 (2028 & >) Greener Airports Globally Interoperable Systems and Data Optimum Capacity and Flexible Flights Efficient Flight Plan ICAO ASBU Executive Briefing 13

Roadmaps? ? ? A slice based on technology. Block 0 Block 1 Block 2 Block 3 + Communications Navigation Surveillance AIM AVIONICS + Plus whatever else we are doing!!! ICAO ASBExecutive Briefing 14

Example of Mapping Performance Improvement Areas Greener Airports Block 0 Block 1 Optimisation of Approach Procedures Including Vertical Guidance (GBAS I) Optimisation of Approach Procedures Including Vertical Guidance (GBAS II/III) Wake Vortex Separation, Refined Wake Vortex Separation (Time-based) Advanced Wake Vortex Separation (Time-based) Runway Sequencing AMAN/DMAN Metroplex Linked AMAN/DMAN Integrated AMAN/DMAN/ SMAN etc. (2013) (2018) ICAO ASBU Executive Briefing Block 2 (2023) Block 3 (2028 & >) 15

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 ICAO ASBU Executive Briefing 16

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 ICAO ASBU Executive Briefing 17

Improvements for Phases of Flight Example: Block 0 ICAO ASBU Executive Briefing 18

A Team Effort ICAO ASBU Executive Briefing 19

What’s Next? • ASBUs initiative formalized at 12 th 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 ICAO ASBU Executive Briefing 20
