Measurements & Validation

Learn about the validation methodology for the European Air Traffic Management System (EATMS), which demonstrates the system's ability to operate effectively in real-life scenarios. Discover the different validation techniques, measurements of merit, and the importance of consistent application of the methodology across all sites.

  2. What is Validation? • EATMS Validation Strategy (EVAS) “The process through which a desired level of confidence in the ability of a deliverable to operate in a real-life environment may be demonstrated against a pre-defined level of functionality, operability and performance”

  6. What is Validation? • EATMS Validation Strategy (EVAS) “The process through which a desired level of confidence in the ability of a deliverable to operate in a real-life environment may be demonstrated against a pre-defined level of functionality, operability and performance” • Validation builds confidence that the system is fit for purpose

  7. How to Validate

  8. How to Validate Analytic modelling Fast-time Field test simulation Shadow-mode Small-scale trial real-time simulation Operational trial Operations Large-scale real-time simulation

  9. Where to Validate Small-scale real-time simulation

  10. Where to Validate NATS DLR CENA NLR EEC real-life environment Small-scale real-time simulation

  11. Validation Methodology • Consistent Application of Validation Methodology Across All Sites

  12. Validation Methodology • Consistent Application of Validation Methodology Across All Sites

  13. Validation Methodology • Consistent Application of Validation Methodology Across All Sites

  14. Validation Methodology • Consistent Application of Validation Methodology Across All Sites

  15. Validation Methodology • Consistent Application of Validation Methodology Across All Sites

  16. Validation Methodology • Consistent Application of Validation Methodology Across All Sites pre-defined levelof functionality, operability and performance

  17. Measures of Merit • MoM’s Chosen to Test Hypotheses • Controller Workload • Airspace Capacity • Quality of Service • Usability • Safety • Measurements Taken: • e.g. Workload: ISA, TLX, R/T, ….. • Objective; Subjective; Observed

  18. Analysis • Descriptive Statistics

  19. Analysis • Descriptive Statistics • Inferential Statistics • significant at 5% confidence level

  20. Analysis • Descriptive Statistics • Inferential Statistics • significant at 5% confidence level • Backed up by Controller Subjective Comments • “I can still handle the aircraft while doing the crossword!”

  21. Analysis • Descriptive Statistics • Inferential Statistics • significant at 5% confidence level • Backed up by Controller Subjective Comments • “I can still handle the aircraft while doing the crossword!” desired level of confidence

  22. Effectiveness of PHARE Validation • Core Validation Group with Representation from all Participating Sites • Common Methodology Crucial • Methodology Improved with Experience • Validation Conducted by Individual Sites • Lessons Re-learnt &/or Lost • Effectiveness Diminished • Validation Should be Applied Throughout Project - Not Just at the End

  23. Summary • Validation Methodology Major Contributor to Credibility of PHARE • Forms the Backbone for much of the Validation Activities within European ATM R&D
