Safety-Critical Personality Aspects in Human-Machine Teams of Aviation

Abstract

Working safely and successfully in highly automated human-machine interfaces of future aviation is not only a matter of performance, but also of personality. This study examines which personality aspects correlate with safety-critical performance in human-machine teams. The research tools HTQ (Hybrid Team Questionnaire) and HINT (Hybrid Interaction Scenario) were combined for a comprehensive exploratory study. The HTQ includes personality scales measuring broad factors of personality (Big Five) as well as more specific scales and was added with objective personality assessments to measure risk taking. The simulation tool HINT simulates relevant processes in future human-machine team interaction in aviation. In a study with 156 applicants for aviation careers, safety-critical relations of some facets of general personality as well as risk taking were found. Especially personality aspects concerning disinhibiting, spontaneous behaviour and sensation seeking show correlations with poorer performance in the HINT simulation.
