Applied techniques and benefits
• Expert Group To discuss high-level and conceptual ideas Operational aspects and feasibility Benefits, priorities, blocking points Agreement, operational participation and portability The role of different experiments
- But no “validated” agreements
• Fast-Time Simulation (FTS) Wide area: Airport, Region, ECAC-wide Large coverage: 24 hours, 10.000nds of flights Quantification, with focus on: Capacity and Efficiency Reproducible
- But simple modelling, adopting validated ops mechanisms

Applied techniques and benefits
• Prototyping Human in the loop, small-scale Focus on feasibility, and operational acceptance Good perception of workload, and procedural details Good modelling of detailed procedures
But:- Simulation is non-deterministic and gives low statistics- Simulation is small-scale and it is difficult to address a
complete scenario

Being specific on how to model a procedure in details of its operational context, (e.g. time and effort to perform datalink exchange)

In Episode 3
• Examples of combining techniques in Episode 3:
ECAC-wide: Macro model to accept FTS and Prototyping results and to extrapolate results on ECAC-wide applicability
Support to Gaming: Airport Gaming and use of ECAC-wide model to feed Gaming with solutions solving bottlenecks by DCB
En-route - TMA coupling: Prototyping of ATM En-route control in support of managed arrival flows, and fast-time simulation of Multi-Airport flows from en-route (200NM out) to landing

Expert Group, example
Feeding FTS: By Story Board, analysing critical parts of concept By dimensioning the operations in time and space By assumptions
Assumptions: Airspace utilisation: With
low variability there is control on the amount of airspace needed to accomplish the sequencing, without ......
Capacity: Without ensured low variability there will be dips in demand resulting in loss of capacity ......

Conclusions
Expert Group: New valuable experience with low effort
and involvement:- High diversity of experts- Intensive discussions and concrete - Inputs in support of experiments- Support portability of concept,
experiments and results
FTS, successful in:- Large-scale simulations- Quantified benefits under “ideal” conditions (upper-bound values)- Assessment of acceptance of achievable benefits (e.g. fuel gains)
Prototyping, successful in:- Human-in-the-loop, small-scale simulations- Assessment of acceptance of operational procedures (e.g. workload and procedures)
