A novel decision support system for complex fault management procedures on-board modern aircraft is presented. The system is designed on the basis of Cognitive Engineering principles and is aimed at improving pilots’ decision-making activity by supporting human cognitive strategies such as mental simulation. Two experiments involving 13 civil pilots are presented. The results show that the framework proposed improves pilots’ decision accuracy, decision performance and situation awareness, whilst reducing mental workload and complacency regarding system advisories. In one of the experiments, pilots are provided with probabilistic values representing the degree of uncertainty embedded in the information generated by the system; whilst both high and low degrees of uncertainty enhance the decision making, medium degrees of uncertainty lead to increased decision complexity and mental workload.
