ICAO Aviation System Block Upgrade Executive Briefing:

1. ICAO Aviation System Block Upgrade Executive Briefing: The Framework for Global Harmonization Issued 10 June 2011

2. 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 ICAO ASBU Executive Briefing

3. 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

4. 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

5. 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

6. 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

7. 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

9. 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 • 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) • 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) • Positive Business Case • Minimum investment; using existing airborne technology • Rollout (Formulation of • business case by States) • Regulatory Approval Plan • Air & Ground • Ops Approval Handbook (2011) • PBN Model Regulations (2011) • Rollout (planning& implementation • by PIRGs/States) ICAO ASBU Executive Briefing 9

10. 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

11. 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

12. 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

13. 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

14. 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

15. Example of Mapping Performance Improvement Areas Block 0 (2013) Block 1 (2018) Block 2 (2023) Block 3 (2028 & >) Greener Airports 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. etc. etc. etc. ICAO ASBU Executive Briefing

16. 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

17. 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

18. Improvements for Phases of FlightExample: Block 0 ICAO ASBU Executive Briefing

19. A Team Effort ICAO ASBU Executive Briefing

20. 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 ICAO ASBU Executive Briefing
