Figure 1 - 7: High Level overview of Scenario & Test Case Comparison
In the above Figure, for each Validation method, every Scenario/Test Case shown in the red rounded-edged box is compared with the Reference/Base Case in the red square box above it.
At the end of the simulation, comparisons and evaluations can be made using absolute values derived from the data collected as workload, capacity figures, etc.
1.5.8 ANALYSING RESULTS
Results obtained from both qualitative and quantitative assessments need to be analysed. In most cases, data obtained from quantitative assessment-type Validation methods need expert analysis e.g. Statisticians. Nevertheless, it is imperative that numerical data andanalysis thereof is also subjected to qualitative assessment so that the overall impact of the results may be understood.

This chapter has introduced Validation in the context of Terminal Airspace design and has explained its purpose and basic principles. In particular, this chapter has stressed the importance of preparation and planning, qualitative analysis and the proper naming and analysis of Scenarios and Test Cases.
Most importantly, this chapter has stressed that when comparing Base and Test Cases, it is imperative that only one parameter be changed at a time so that the effect of the change can be measured.

Unlike the topics discussed in other chapters in Part D, (e.g. fast- and real-time simulation), Qualitative Assessment is not a stand-alone method of validation. Indeed, ‘assessment’ is not exclusive to the validation phase which is why qualitative and quantitative assessment were introduced under the Design Methodology. Assessment - particularly Qualitative Assessment – is a ‘constant’ through the entire life-cycle of the Terminal Airspace design project i.e. during project planning, the conceptual design phase, validation and implementation/review phase . 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：EUROCONTROL MANUAL FOR AIRSPACE PLANNING 2(90)
