Agenda• ADS-B Package 1
– Ground Surveillance Application– Airborne Surveillance Application
• ATSAW : PO-ASAS level 1 application• ASAS : PO-ASAS level 2 application
• Sequencing and merging application – Global architecture– Arrival and departure manager– FDPS – HMI– Data-link CPDLC– ADS-B network– Training tools– Recording
• Preliminary conclusion

ADS-B package 1 GSA
• Non radar area surveillance– Ground ADS-B station
• Should not be very expensive compared to a radar• Installation cost can be the most significant (e.g. access
road)
– Controller HMI• Not really different from radar surveillance
• Airport surface surveillance– Complement an existing SMGCS– Enable SMGCS on medium or small airport
• Complement radar surveillance– Integration with Mode S radar stations– Additional ADS-B infrastructure

ADS-B package 1 ASA
• ATSAW– A priori no impact on ground ATM system
• If no difference in operational procedure
• ASA– In trail procedures
• Oceanic environment
– Passing and Crossing application • Difficult to assess real impact on ATM system and
responsibility sharing between pilot and controller
– Sequencing and merging • Co-Space demonstration • Potential benefit for extended terminal area • Operational concept to be further defined
– preliminary impact assessment on ground system

Sequencing and merging application
• Arrival and departure manager– Takes into account aircraft capability– Provides the controller with a proposed
sequence and prepares instruction for sequencing• Time or distance separation
– Impact on trajectory prediction
• FDPS– Aircraft capability indicated in flight plan ?– Trajectory prediction

Sequencing and merging application
• Controller HMI– Display of aircraft capabilities
• ADS-B out for target aircraft• ASAS capability for trailer aircraft
– Display of linked aircraft– Designation of target and trailer aircraft– Allocation of a separation
• Integrated with arrival departure manager specific function
– Monitoring of separation• Appropriate new warning tools
– Between MTCD and STCA
– Recovery function– Termination of the ASAS separation

Sequencing and merging application
• Need for data-link– Enhanced CPDLC is probably the best
solution to give sequencing and merging clearance
• Unambiguous identification of aircraft• Easy integration of data into airborne systems• Ensure consistency between air and ground
views– Need for new messages to be defined by ICAO
• Enhance ATN CPDLC communication stack
– Upgrade of communication systems (eg Air server)– Additional CPDLC functions in controller HMI

aérienneSequencing and merging
application• ADS-B network
– Reception of ADS-B data on ground is needed• Confidence in ADS-B current capabilities of each aircraft• Improvement of radar surveillance with ADS-B may be
necessary– Specific ADS-B ground stations or– Enhancement of Mode S radar capabilities
» Omni directional 1090 MHz reception capabilities
– Enhance radar tracking with ADS-B• Integrity monitoring with radar data• Combination of ADS-B and radar for enhanced tracking• ARTAS
– Radar networks impact

Sequencing and merging application
• Other tools– Training simulator
• All previous capabilities must be available in controller training tools
• Pseudo pilot new tool to manage sequencing • Simulation of new trajectories
– Monitoring of ADS-B ground stations– Recording
• ADS-B data• Sequencing and merging specific events

aérienne Conclusion
• A very preliminary analysis– new concept and new procedures always
impact the ATM system– Too early for any Cost assessment– Safety implications
• Is a unique data-link sufficient ?• Development level of ATS system supporting ASAS
– Transition to be considered• Need for TIS-B
– Transition accommodation feasibility with TIS-B ?• ASAS capabilities to be integrated in ATS system
development plan• Implementation timescale is difficult to assess

aérienne Conclusion
• From ASAS spacing to ASAS separation– Spacing is supposed not to change task
responsibility sharing and separation minima– ASAS separation will impact both
• Controller tasks to be defined– Strategic air traffic management– Monitoring
• Airborne separation minima to be defined– Fixed or dynamic– Coordinated with ground ATM ?
• Recovery procedures and tools
• Spacing is a huge step, separation will be even bigger
