ADS-B Step 1 : ADS-B OUT
• Today, transponder installations with ADS-B are certified on a non-interference basis.
• Certification achieved on A380A380 is the first aircraft certified for Non Radar Operations
ED-126 (with DO-260A)
• Certification ongoing on A318/319/320/321, A330/A340 family, for Non Radar Operations (with DO-260)
No change in current installations expectedTarget date : End 2007

ADS-B Step 2 : ATSAW
• ATSAW is achievable in the short termNot demanding (cert. level, ADS-B performance data)Existing ADS-B Out seems sufficient Provides its own benefits
• ATSAW will help gaining experience & confidence (flight crew, technical) on ASAS
• Target date for certification on Airbus aircraftAirborne use => 2009Flight tests ongoing with A320 flight test aircraft

•Fully integrated solution•Traffic displayed on the primary field of view
•Limited impact (no new equipment)
Additional information on MCDU
•High commonality with A380&A350 solution

ADS-B Step 2 : Example of ATSAW benefitsOceanic environment
• ATSAW OnlyUse of ATSAW to detect climb opportunitiesCurrent separation minimaCurrent phraseology
• ATSAW – In Trail Procedure (ITP)Implementation of a new procedureBased on ATSAWReduced separation minima during the climbNew phraseology

1]. ATSAW : Detect Climb Opportunity
ATSAW combined with Datalink Communications
allows to obtain better Flight Levels

Step 3 : ASAS Spacing
• Promising benefitsCapacity / Regularity due to less radar vectoringCombined with CDA => may reduce fuel consumption and emissionsProbably more beneficial at secondary airports
• Part of the Intermediate baseline (2013) of SESAR
• Airbus target : Sequencing&Merging application for pioneer : 2013 timeframe
Automated solutionLimited impact : Software only, using ATSAW baseline
• Procedural and ground system impactsTo be addressed in parallel by ANSPs within SESAR

Step 4 : ASAS Separation
• Principle
The controller delegates separation relative to designated aircraft through a new clearance
The controller is responsible for providing separation from other aircraft
• ASAS Separation is envisaged for the 2020 timeframe
E.g. Responsibility to “Remain behind” a target entirely transferred to the aircraft in all weather conditions
• Concept and associated transitions to be refined

Solutions are currently prepared for bothADS-B Out and ADS-B In
SESAR and NEXTGEN should drive ASAS development
