3. Longer-term Objective: High Performance
4 Main Performance improvement areas
Airport operations
Globally interoperable systems & data
Optimum capacity & flexible flights
Efficient flight path
… increasingly interrelated as ATM is closer to optimum functioning
when getting closer to optimum in a complex system, most of the modules in fact impact several performance areas, or apply more and more to all flight phases, especially when considering the trajectory, a continuous object by nature

B2/3 are important to be timely ready. This is also true for Block 1. Adding the different phases justifies why V1 and V2 may need be started now for B3, and why ICAO work may or may not be urgent/intense on some topics. There is unfortunately no universal duration and it is premature in the TT work to have a more precise plan V7 V7

5. 3 Essential Considerations in the Global ATM Operational Concept
The network of actors & assets
The flight trajectory over time
Measured business performance
Network
Trajectory
Performance
Informed decisions taken collaboratively on early and accurate information
Partnership – Interoperability
SWIM and data comm. are cornerstones
Preparatory Workshop for AN-Conf/12 5

6. International Technical Challenges
To ensure interoperability, in particular
Common time reference
New flight plan / flight object (FF-ICE)
4D Trajectory exchange format
Information Management (data models, quality of service requirements, sharing rules, distribution process)
D/L applications for trajectory data exchange
Procedures for delegation ATC/Pilots
Time based separations
New wake vortex separations based on time
Participation of all airspace users
Ops changes cannot materialise if not properly supported by the enabling technologies
In red, issues solved by previous blocks.
Will require new ICAO material and industry standards
Preparatory Workshop for AN-Conf/12 6

7. Preparatory Workshop for AN-Conf/12
Global Perspective
Global traffic development spreads the same issues globally
-> We need global standards/interoperability, and not wait too long for that
-> Too many intermediate steps/standards make evolution more difficult
Deployment where and when needed, but based on common principles/rules/data & interoperable technologies
-> One size does not fit all
-> B2/3 implementation decisions not required now!
Importance of MOCs, of demonstrations made in different operating environments, anticipating on deployment conditions
Cooperation early in life cycle is more efficient
-> Among programmes, within/across regions, with ICAO
-> On requirements, R&D activities

16. Challenges - How to Get There?
Technical evolution towards Global ATM Concept
Multi-facility (ATC, aircraft, airport) consistency
Network-wide effects increase interdependence & sensitivity of solutions to local situations & perturbations
Increased cooperation within regions to optimise synchronised deployments
Inter-regional flights & cooperation as cement
Particular care to non-nominal situations upstream in the work
Need for interoperability / new standards
Validate, demonstrate, standardise
Preparatory Workshop for AN-Conf/12 16

17. Challenges - How to Get There?
Ensure timely success of B0 & B1
As success story of an unprecedented global effort
As preparatory/initial steps (not requiring implementation of all modules)
To ensure availability of resources
Agree on the way ahead and research programme
No implementation decision now!
