Trust Observations in Validation Exercises

This paper is concerned with an operational account of trust. It reports our experience in observing different trust aspects during a validation session for the assessment of a new tool and relevant operational concepts in the Air Traffic Management (ATM) domain. Despite the fact that trust is yet an elusive concept, our results show how monitoring trust can support the validation of alternative system settings and their operational aspects. This paper reports our experimental work on observing trust during validations exercises. Moreover, it provides new insights about the nature and the investigation of trust.
