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.

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

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

Advantages

• Flexibility

• Short duration

• Suited to early concept assessment/maturation

• Reduced cost: small scale and simplified environment, to focus on specific issues

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

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)

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

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

In Conclusion

• Operability – user perspective go/nogo

• Iterative

• Cost-effective

• Continuity

• Short-Time as benefit and constraint

• Clear target

• Part of wider validation framework
