ASAS Dream or reality? ASAS TN Workshop April 2003 Presented by Thomas Fixy Manager Air Traffic Information Management
© AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. April 2003Page 2 ASAS : what and why? A set of applications based on the real time use of broadcasted traffic data (ADS-B) Objective : to enhance flight and ground operations (safety, efficiency, etc) ASAS Package 1 : presently 12 applications for Situation Awareness and Spacing 5 applications for ground surveillance (GSA) 7 applications for airborne applications (ASA)

The US SF21 Capstone Alaska (UAT) CAA Situation awareness CDTI Not useful for continental radar areas RTCA MASPS & MOPS. However FAA agreed to joint US/EU work. ... Europe ASAS Trials based on VDL4 Propose to lead RFG for applications harmonisation ... Asia Pacific region Australian trials for Radar Like Application (separation) 1090 ADS-B out mandate proposed by Australia for 2006 ...

How to start?
© AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. April 2003Page 12 Start small ASAS before 10 years is a DREAM Airline financial situation, maturation time, deployment (retrofit), standardization process, certification, etc 1090 : Use existing aircraft installation : Avoid costly modification initially (i.e. FMS). VDL4 requires installation of additional new radios for surveillance, additional antennas and location (wiring), requires 6-12MHz guard bands to mitigate interference with essential VHF voice radios these characteristics make VDL 4 costly to install, and inefficient of spectrum use L-Band more adapted to aircraft system integration (AEEC Integrated Surveillance System supported by Airbus and Boeing, A380 AESS, etc)
© AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. April 2003Page 13 States to mandate ADS-B out For efficient ASAS, all aircraft must be equipped except maybe for some specific operations (spacing at HUBs? Night operations?) If all a/c manufacturers are not committed, ASAS is a DREAM ADS-B Out is a pre-requisite to all Package 1 applications ADS-B Out is a REALITY today Mandate ADS-B Out will accelerate the development & deployment process Based on DO260A and on existing aircraft installation as first step

April 2003Page 14 Reality: time-to-market life cycle Operational Concept Validation : 5-7y Concept definition, feasibility and acceptability Standardisation (OSED), regional harmonisation Safety case – global Benefit assessment Implementation planning Industrialisation : 5-7y Standardisation (Safety, performance, interoperability) Technological development –Includes systems development, validation and large scale pre- implementation trials, certification process. Usual development cycle: air and ground harmonisation –Multiple developments for Forward-Fit/ Retro-Fit Deployment : 3-5y In both air and ground “fleets” Voluntary or mandated deployment

© AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. April 2003Page 16 ASAS Standards Urgent need for harmonised definition and need Airbus needs a unique definition –Regional solutions, maybe inevitable, but are a burden Guaranteeing world-wide interoperability Clear need still lacking from stakeholders (Airlines/ATSP) except Australia & Alaska : Radar Like (ADS-B out) & ATSAW (CDTI) RFG : harmonised OSED Today scarce ATSP/Airlines resources to work on OSED!!!! –caution : only DLH & EEC Bretigny, representing Airlines/ATC community Eurocontrol, FAA, and European ATSP’s have a crucial role Risk : OSED/SPR/Interop remain a dream –the reality : RTCA MASPs/MOPS
© AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. April 2003Page 17 Crucial : Human factors & training What to present to pilot? What not to present? What range? Which display? How to merge TCAS info with ASAS info? How to process conflict? Procedures? Etc… This is being worked in research programs, TIM ASAS, etc. Human Factor validation of the proposed solutions needed All these aspects must be addressed if we think to transfer tasks or responsibility from controller to pilot. We are still far. Important impact on pilot repartition task, then procedures. Specific qualification (such as cat 3) with recurrent training? Managed at Airline level has important impacts Today training for CPDLC is an issue for airlines
© AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. April 2003Page 18 Conclusion ASAS is only a tool ASAS must be integrated in a global concept of operations that will maximize its benefit Start with pre-requisite: mandate ADS-B Out The paradigm change will come from the operational use (procedures, ATC/pilot task repartition, etc) and the way ASAS will be integrated into a global concept : Single European Sky (OSED) Take into account industry capacity Define the need and ensure harmonisation Start with simple applications Ground applications Airborne applications with minimum system impact Carry on R&D!
