1 A I R T R A F F I C O R G A N I Z A T I O N Future Communications Study Technology Assessment Team: Suggested Phase III Activities Presented at ICAO ACP WGC Meeting, Brussels, Belgium September 19, 2006 Prepared by: ITT/Glen Dyer, Tricia Gilbert NASA/James Budinger

2 2 Background Phase III of the Future Communications Study (FCS) technology investigation has recently commenced –Focus of Phase III is detailed investigation of two additional technologies initially screened in Phase I and II activities to evaluate applicability for the future radio system Phase III builds upon knowledge gained in first two study phases –General technology knowledge (e.g. technology concepts of use for aviation application) –Evaluation criteria knowledge (derived and traceable evaluation metrics) –Detailed technology investigation knowledge

3 3 Phase III Detailed Technology Evaluation Activities Three major task areas have been identified 1.Screened Technology Analyses (with focus on technologies not yet investigated) Candidate technologies for additional detailed investigations include W-CDMA, B-VHF and L-Band E-TDMA Common Model/Tool Development 2.DME and Mode S Interference Measurements 3.Final Technology Evaluation and Recommendations

4 4 Task Area 1: Screened Technology Analyses Objective –Detailed analysis of the suitability of Phase II recommended technologies as FRS solutions Initial technology study focus is WCDMA Other candidates: B-VHF or E-TDMA –These are the best performing technologies that have not yet been analyzed in detail –The goal of this activity is to determine each of these technologies as fitting into one of the following categories as a FRS solution A totally suitable existing technology for the FRS A custom solution for the FRS to meet aviation needs A hybrid technology solution

5 5 Task Area 1: Screened Technology Detailed Analyses

6 6 Task Area 1: Common Model/Tool Development Overview Approach identified in original FCS documentation calls for simulation of screened technologies, for example: –Define common environmental models/loading scenarios for evaluating technologies –Build representative models for candidate technologies –Evaluate technology performance Must ensure developed tools/models for Phase III analysis address the range of evaluation criteria proposed for technology selection, including –Technical criteria – addressing required functionality and performance of the future radio system –Institutional criteria – addressing factors of a technology that make it a viable candidate solution (e.g. cost/risk factors)

7 7 Task Area 1: Example Evaluation Tools/Models Evaluation CriteriaTechnology Detailed AnalysesAnalyses Tools/Models Functional CriteriaFunctional Capability - ATC and AOC A/G and A/A Addressed Data and G-A Broadcast Data Capability Functional flow diagrams, sequence diagrams, swim lines Rational Rose; CORE; any appropriate diagramming tool Communication Performance – Latency, QoS, Capacity, Number of Users Protocol Simulation Physical Layer Simulation Common Traffic Model; Common Channel Model Institutional CriteriaMaturity for Aeronautical Environment - Technical Readiness Level Not requiredAssessment by Inspection Maturity for Aeronautical Environment - Standardization Status Not requiredAssessment by Inspection Maturity for Aeronautical Environment - Certification Issues Detailed assessment of safety aspects of system Tools to diagram and capture fault tree analysis Cost – Ground CostCost AnalysisCost Model Methodology; Cost Model Assumptions Cost –Avionics CostCost AnalysisCost Model Methodology; Cost Model Assumptions Spectrum ProtectionNot requiredAssessment by Inspection SecurityVulnerability AssessmentSecurity Assessment Methodology Transition – ROI, technical migration (including integrity and availability performance), and operational migration Availability AnalysisCommon Architectural Assumptions

8 8 Task Area 1: Tool Development Objectives and Approach Objective –Develop consensus on required tools/models for future radio system technology evaluation –Tool/model development Approach –Participate in consensus meetings to identify tools/models required for technology evaluation –Determine format for tools/models –Support tool/model development and validation

9 9 Task Area 2: DME and Mode S Interference Measurements Objective –Further characterization of DME and Mode S equipment interference performance against proposed modulation types for the FCS; particularly susceptibilities from the following types of equipment CDMA MCM Narrowband Digital Approach –This activity will consist of the six interrelated tasks shown in the figure

10 10 Task Area 3: Final Technology Evaluation and Recommendations Objectives –Solicit, collect, and assess a wide range of stakeholder inputs and feedback –Perform the final technology evaluation and develop appropriate recommendations Approach –Combine technology performance assessment against derived criteria with synthesis of a wide range of stakeholder input/feedback to fully reflect stakeholder requirements Facilitated through a more extensive application of the defined Analytical Hierarchy Process

11 11 Action Request The ACP Working Group is invited to consider the technology investigation activities described in this paper, and provide comments if desired It is recommended that the ACP Working Group discuss and agree upon the desired outcome of the Future Communications study It is recommended that the ACP Working Group discuss and agree upon the need for a comprehensive modeling approach against all evaluation criteria and specify model structures for each
