Episode 3 - CAATS II Final Dissemination Event 2 Content What is Prototyping Approach Advantages Limitations Prototyping objectives Different Strategies – En-route et TMA En-route experience Expert Groups En-route Results Issues/Next Steps… In Conclusion

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 3 What is it useful for? Human in-the-loop experiments to build the ATM environment piece by piece and to address detailed issues (e.g. airspace, tools, roles). The focus is on operability.

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 4 What is the Technique? Real-time technique Small-scale and/or part-task Iterative in nature Gradually building and refining Examine the options, moving towards a clear goal

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 5 Approach Iterative process Allows modification of a specific research question to be introduced between sessions The overall approach needs to be structured Reasonable and achievable objectives

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 6 Advantages Flexibility Short duration Suited to early concept assessment/maturation Reduced cost: small scale and simplified environment, to focus on specific issues

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 7 Limitations Short-time scales are the major limitation  One week sessions  Time between sessions Training time Limits  Examinination of the concept with multiple conditions  Trends rather than performance measures  Time to perform platform changes and tests between sessions

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 8 Prototyping objectives Main objectives: initial assessment of operability and acceptability, refinement/maturation of a defined set of concept elements Secondary objectives: initial trends on some KPAs (Fast Time/Modelling required to provide consolidated performance figures)

Expert Groups

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 14 En-route Results Airspace  Fixed route network for arrival/departure flows (segregated from overflights)  Redesign sectorisation to suit traffic flows and segregated routes  Know vertical profile as part of RBT Tools  Sector exit lists  Medium Term Conflict Detection (MTCD)  Trajectory Editor (TED) Training  Method and duration (continuity of ATCos would help) Controllers happy that their recommendations appeared in subsequent sessions and during sessions

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 15 Issues/Next Steps… Additional Nominal Situations  Weather  Mixed Equipage  Dynamic Military Activity Prefered Trajectories  Company preferences  ANSP preferences Operational Environment  Information from cockpit to ATCO  Support tools

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 16 In Conclusion Operability – user perspective go/nogo Iterative Cost-effective Continuity Short-Time as benefit and constraint Clear target Part of wider validation framework
