5. ADS-B OUT – AIRBUS POSITION • Airbus supports initial ADS-B OUT certification and operations based on existing equipment. • no need to retrofit the current transponder • a quickly available solution • reduction of cost for airlines, transponder suppliers and Airbus. • Support from : Airservices Australia , CASA, Eurocontrol, Honeywell, ACSS, Collins, etc. • ADS-B parameters transmitted by Airbus aircraft: • Transponders capable of ELS/EHS/ADS-B • No need for pin programming to activate • Presently certified on a non interference basis • 3-steps strategy

6. ADS-B OUT implementation – 1st step 1st step : Initial certification of ADS-B OUT for operational use • Performance declaration of ADS-B Out capacity in Aircraft Flight Manual by Airbus • Operational approval for the intended application (e.g. taking into account end-to-end needs) to be performed by users • Airbus declaration of performance for in-service aircraft will be useful to: • Develop end-to-end certification material • Acquire experience in ground applications (NRA) • Acquire experience in initial airborne applications (ATSAW) • Refine the needs and update the standards • Identify limitations or issues of current installations • Target date for ADS-B Out capability certification on Airbus aircraft: End 2006

7. ADS-B OUT implementation – 2nd step 2nd step: Look into the future • ASAS applications may require additional ADS-B out messages: • Emergency/priority status message • Aircraft category (Light, Medium, Heavy) • Target state status message (i.e. target altitude, target heading) • Aircraft operational status • Waypoints, trajectory, etc… • Others? • RFG is currently working on ASAS applications to • Define the operational needs, • Develop the minimum Interop / Perf / Safety Requirements

8. ADS-B OUT implementation – 3rd step 3rd step: New development • Airbus applies evolutions to transponders: • Continuous improvement (integration, reduction of weight and consumption…) • Additional parameters depending on RFG definition of ASAS applications • Comply with implementation plans and mandates (e.g. DO-260A for USA) • Airbus objective is to get best trade-off between value of additional data versus cost of upgrade

9. How to drive ADS-B IN in the aircraft? Key drivers • Sufficient ADS-B Out quality / deployment • ADS-B Out 3-steps roadmap • Need to be further discussed within industry • Airbus is advocating industry to investigate if current ADS-B Out is sufficient for initial ADS-B IN application • Benefits for those who equip with each ADS-B IN package • Ensure transition path • Develop the ATSAW aircraft function to gain early benefits • Understand next ASAS steps needs to take provisions in ATSAW development • Harmonize early implementations of Sequencing&Merging standardization : UPS needs and other needs.

10. Use of ATSAW on oceanic environments • ATSAW Only • Use of ATSAW to detect climb opportunities • Current separation minima • Current phraseology • ATSAW – In Trail Procedure (ITP) • Implementation of a new procedure • Based on ATSAW • Reduced separation minima during the climb • New phraseology

11. Oceanic CNS concept : ATSAW Only 1]. ATSAW : Detect Climb Opportunity 2]. CPDLC Clearance exchange 2119Z FROM KZAK CTL OPEN CLB TO AND MAINTFL360 • 0]. RNP, ADS-Contract, Direct Com • Reduction of separations • Improved Flexibility *UNABLE STBY* <OTHER WILCO* ATSAW combined with CPDLC allows to use flexibility

12. Oceanic CNS Concept : ITP Procedure

13. ATSAW Over Oceans • Significant fuel saving due to flight at the optimum flight level • Validation needed • Maturity of ITP procedure needs to be gained • Technical / Operational assessment still needed • Eurocontrol funded CRISTAL ITP project to validate the procedure in the North Atlantic • Equivalent projects in Australia and the USA • Even without ITP procedure, benefits of ATSAW aircraft function over oceans & remote areas • Helps flight crew to detect climb opportunities • Enhanced Traffic information broadcast application (TIBA) • Enhanced traffic situational awareness

14. Oceanic to continental transition : Datalink • FANS-1/A : from 1995 • Began in South Pacific then expanded in other oceans • A lot of experience was gained there • Technical maturity (e.g. HMI, FMS) • Procedure feedbacks (e.g. Ambiguous CPDLC messages) • Flight Crew training feedback • Controller training feedback Link2000+ : Datalink deployment in core Europe • Many lessons learnt from FANS-1/A experience

15. Oceanic to continental transition : ATSAW • ATSAW over oceans • Immediate benefits to those who equip = Fuel savings • Similar opportunity to datalink communication experience • From FANS 1/A to Link2000+ • From ATSAW oceanic to continental • Eurocontrol and FAA coordinated actions (AP22) for operations convergence • Right path to spark off ASAS use in continental airspace

16. ATSAW : Early benefits in continental environment • Visual separation approaches aided by ATSAW • Better identification of target aircraft • Anticipation of speed changes • Enhanced traffic situational awareness in continental environment • Better understanding of the arrival sequence at dense airports (even where visual separations are not used) • Better anticipation of ACAS situations • ATSAW will help in gaining experience & confidence (flight crew, technical) to prepare future applications

17. ATSAW : main steps Validation & Development • 2007 : Cristal ITP oceanic operational procedure trials • end 2008 : Target date for ATSAW certification on Airbus aircraft Deployement • Oceanic use of ATSAW • Introduction of ITP oceanic procedure supported by ATSAW • Continental use of ATSAW Future • When ADS-B Out performance permits, introduction of ATSAW on surface

18. Pragmatic way to drive ADS-B IN in the aircraft Standardization => RFG Package I definitions • Understand ASAS Next steps • UPS experience => Research Develop ATSAW => Early use over oceans ADS-B Out => International deployment and improvements ADS-B IN
