1 A I R T R A F F I C O R G A N I Z A T I O N Technology Pre-Screening: Process and Evaluation Presented at ICAO ACP WGW Meeting, Montreal Canada June 27, 2005 Prepared by: FAA ATO/Brent Phillips, Eurocontrol/Jacky Pouzet NASA/James Budinger, ITT/Glen Dyer, Ron Bruno, QinetiQ/Phil Platt

2 2 Briefing Outline Context of the Study Candidate Technologies Families Technology Pre-screening Process Evaluation Criteria Development Process and Criteria Common Findings of Pre-screening Action Request

3 3 Context of the Technology Pre-screening Aeronautical air-to-ground VHF channel capacity for Air Traffic Management (ATM) is reaching saturation –Most severe in Europe and parts of the United States Various proposals to address this problem have been offered and approved independently; none has achieved global endorsement ICAO is seeking a common, global solution through the Aeronautical Communications Panel (ACP) The FAA and Eurocontrol initiated a bi-lateral study of the problem with the support of NASA to provide major input to ICAO ACP in its search for a global solution –Action Plan 17 (AP-17) provides the study terms of reference and outlines a research plan –This Technology Pre-screening Study is Task 3.1 as defined in AP-17 A I R T R A F F I C O R G A N I Z A T I O N

4 4 FAA/Eurocontrol Joint Study –FAA/Eurocontrol 3 year joint study* –Objectives: Identification of requirements and operating concepts Investigation into new mobile communication technologies Investigation of a flexible avionics architecture Development of a Future Communications Roadmap Creation of industry buy-in Improvements to maximise utilisation of current spectrum * Federal Aviation Administration/EUROCONTROL, Cooperative Research and Development Action Plan 17: Future Communications Study (AP 17-04) CCOM FAA/EUROCONTROL Coordination Committee

5 5 Technology Identification In order to identify all technologies that may be applicable to aeronautical communications, a multi- faceted approach was used for technology identification: 1.A survey of widely used and successful commercial and military technologies was conducted to identify technologies that offered potential value to A/G communications 2.NASA released two Requests for Information soliciting technology candidate inputs from industry 3.Eurocontrol received input from European manufacturers 4.Technology candidates previously identified by the ICAO ACP WG-C were included in this study In all, over 50 technology candidates were identified in this process

7 7 Pre-Screening Process Identify Candidate Technologies Technology Not Considered Further Evaluate Technology and Calculate Relative Score Yes Technology Not Considered Further No Conduct Comparative/ Sensitivity Analyses Characterize Technologies (WG-C Templates) and Conduct Analysis Common Evaluation Criteria No Task 3.1 AP17: Pre-Screening Identification, Characterization, Evaluation Yes Task 3.2 AP 17: Technology Investigation Detailed Technology Analysis and Selections Exclude inappropriate technologies, e.g. direct broadcast video These technologies provide no unique value for aeronautical communications within the scope of their family These technologies provide no unique value for aeronautical communications within the scope of all candidate solutions FAA/Eurocontrol Decision Process Is Technology one of the Best Solutions? Bring Candidate Forward Meets Minimum Threshold Requirements ?

8 8 Minimum Threshold Criteria A very large number of technologies were identified in the study and, of necessity, some were culled from further consideration without a detailed analysis being performed. The culling rules were: –A proprietary technology was eliminated if an another technology in the family that is based on an open standard provides comparable value –An immature technology was eliminated if a more mature technology in the family offered comparable value [Note: Assumed 2015 in-service date] –An older (near end of life) technology was eliminated if a successor mature technology in the family provided equal or greater value with no expected cost impact –A technology that inherently relies on unprotected spectrum [i.e., not AM(R)S or AMS(R)S] was eliminated –A technology was eliminated if another technology in the family provided comparable value and was more widely implemented (sparse implementation) –A technology was eliminated if it could not support a practical transition

10 10 Consensus Evaluation Criteria Technology pre-screening evaluation criteria were derived via a consensus process during 2004 July – ITT Synthesizes evaluation criteria from 11th ICAO Air Navigation Conference (Sept/Oct 2003) recommendations August – ITT and QinetiQ work towards refining the evaluation criteria, and developing a consensus set of criteria. In parallel, the FAA RTTA team is developing a set of evaluation criteria September – A mapping between the ITT and QinetiQ consensus criteria and the independently developed RTTA criteria is developed and presented to the FAA. Mapping shows substantial overlap, and highlights missing criteria in the ITT and QinetiQ set, which are adopted. Evaluation criteria are baselined, and the FAA RTTA team begins work of defining evaluation metrics October – Through two rounds of FAA comments, ITT and QinetiQ replies, and then a round table discussion between ITT, NASA and the FAA RTTA team, evaluation metrics are decided and harmonized. In the process, some of the evaluation criteria are modified. An additional criteria, transition is adopted, and one criteria, COTS Leveraging, is eliminated. The evaluation criteria and metrics are placed under configuration control on October 7, 2004.
