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

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 materialAcquire 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

ADS-B OUT implementation – 2nd step

2nd step: Look into the future

• ASAS applications may require additional ADS-B out messages: Emergency/priority status messageAircraft category (Light, Medium, Heavy) Target state status message (i.e. target altitude, target heading)Aircraft operational statusWaypoints, trajectory, etc…Others?

• RFG is currently working on ASAS applications toDefine the operational needs,Develop the minimum Interop / Perf / Safety Requirements

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

applicationsComply 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

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.

ATSAW Over Oceans

• Significant fuel saving due to flight at the optimum flight level

• Validation neededMaturity of ITP procedure needs to be gainedTechnical / 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

Oceanic to continental transition : Datalink

• FANS-1/A : from 1995Began in South Pacific then expanded in other oceansA 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 EuropeMany lessons learnt from FANS-1/A experience

Oceanic to continental transition : ATSAW

• ATSAW over oceans Immediate benefits to those who equip = Fuel savings

• Similar opportunity to datalink communication experienceFrom 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

ATSAW : Early benefits in continental environment

• Visual separation approaches aided by ATSAWBetter identification of target aircraftAnticipation 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
