APIRG/18 IP/9 12/2/2012 INTERNATIONAL CIVIL AVIATION ORGANIZATION AFI PLANNING AND IMPLEMENTATION REGIONAL GROUP EIGHTEENTH MEETING (APIRG/18) Kampala, Uganda (27 30 March 2012) Agenda Item 3.4: Communication Navigation and Surveillance (CNS) ATM System Block Upgrade (ASBU) (Presented by IATA) SUMMARY Block upgrades describe a way to apply the concepts defined in the ICAO Global Air Navigation Plan (Doc 9750) with the goal of implementing regional performance improvements. It includes the development of technology roadmaps, to ensure that standards are mature and to facilitate the synchronization between air and ground systems, as well as between regions. The ultimate goal is to achieve global interoperability. Safety demands this level of interoperability and harmonization. Safety must be achieved at a reasonable cost with commensurate benefits. Aviation System Block Upgrades comprise a suite of capabilities, called modules, each having the essential qualities of: A clearly-defined measurable operational improvement and success metric; Necessary equipment and/or systems in aircraft and on ground along with an operational approval or certification plan; Standards and procedures for both airborne and ground systems; and A positive business case over a clearly defined period of time. Block upgrades are separated by a period of five years, with initial operating capability (IOC) for Block 0 currently available; for Block 1 from 2018; for Block 2 from 2023; and for Block 3 from 2028 and beyond. Block 0 modules that which are available NOW! In implementing Block upgrades, it is recognized that all module solutions are not required in all airspaces. REFRENCE(S): ICAO Doc 9750 Global Air Navigation Plan; ICAO Doc 9854 Global Air Traffic Management Operational Concept Related ICAO Strategic Objective(s): A & C 1. INTRODUCTION 1

1.1. ICAO launched the Aviation System Block Upgrades initiative to progress outcomes of its 37th General Assembly in terms of facilitating interoperability, harmonization, and modernization of air transportation worldwide. 1.2. To that end, ICAO established a programmatic, collaborative approach to develop a set of air traffic management (ATM) solutions to meet the global needs for an interoperable airspace that takes advantage of current equipage, establishes a transition plan that provides key performance improvements, and enables global interoperability. 1.3. The concept of the block upgrades originates from existing near-term implementation plans based largely on operational concepts extracted from the United States NextGen, Europe s SESAR and Japan s CARATS programmes and is aligned with the ICAO Global Air Traffic Management Operational Concept (Doc 9854). 1.4. The intent is to apply key capabilities and performance improvements, drawn from these programmes, across regional and local environments with the same level of performance and associated benefits on a global scale. 1.5. Block upgrades are organized in five-year time increments starting 2013 as follows: a) Block 0: available now b) Block 1: available to be deployed globally from 2018 c) Block 2: available to be deployed globally from 2023 d) Block 3: available to be deployed globally from 2028 1.6. The block upgrades initiative should constitute the basis for future plans for ATM modernization. Where plans are in existence, they should be revised in line with objectives defined in the block upgrades. a) For the Industry, this constitutes a basis for planning future development and delivering products on the market at the proper target time. b) For service providers or operators, block upgrades should serve as a planning tool for resource management, capital investment, training as well as potential reorganization 1.7. A key element of a block upgrade is to ensure that all of its capabilities and performance modules reflect proven operational applications and technologies, along with validation (and data) of the cost/benefits of implementation. This process should embrace ICAO approach of Collaborative Decision Making process. 2. DISCUSSION 2.1. Implementation of any Block 0 module (Appendix A) must leverage on existing onboard avionics. 2.2. Airlines have invested in Area Navigation (RNAV) Systems as the primary enabler for the implementation of Performance Based Navigation (PBN); 2.3. In this regard, IATA sees PBN as the main enabler for Block 0 operational 2

improvements. PBN, complemented by Continuous Climb Operations (CCO) and Continuous Descent Operations (CDO), will contribute to several ICAO strategic objectives: a) Safety Main enabler to address CFIT and un-stabilized approaches b) Access Due to flexibility and application of modern on-board avionics to its full extent, more runways are accessible (previously not accessible, or by less safe circling, offset or steep angle approaches) c) Efficiency Through application of modern on-board avionics to its full extent, positioning of routes, SIDs and Stars is not constraint anymore by location of navaids, but can be put virtually anywhere (airspace optimization, less fuel burn, less delays, workload decrease). d) Environment CDO and CCO reduce fuel burn (less CO2 emissions) and noise. 2.4. Before committing to any investment on equipage for Block1/2/3 (Appendix A) a sound and realistic business case must be developed for all proposed operational improvements. Operational business case is essential. Business case justification for future equipage will be strengthened by demonstrating benefits from the use of current equipage. 3. ACTION BY THE MEETING 3.1. The meeting is invited to: a) Embrace the Aviation System Block Upgrade framework as the unified planning mechanism to ensure harmonization and interoperability, driving regional planning; b) Work closely with all aviation stakeholders in the region, whose investment decisions are interdependent. c) Prioritize implementation of PBN, CDO and CCO as the main enablers for Block 0 operational improvements. d) Ensure the development of sound and realistic business cases before asking for committing to any investment on equipage for Block1/2/3. -END- 3
