Communicating data-driven risk information to pilots

General Aviation safety is a pressing concern. In this research, we consider the factor that appears most often in accidents: the pilot. Newly-licensed pilots can fly without their instructor, potentially as the only or most experienced pilot in the aircraft. Commercial debrief products use technology in the flight deck to collect data and provide post-flight visualizations for performance reviews, but do not discuss flight safety. To manage risk, though, pilots need to perceive the risk associated with a situation before deciding whether they are willing to accept it. Safety-driven post-flight feedback may help address performance. However, it is not clear whether and how the way we present feedback affects how pilots perceive risk, or what the best way is. We designed and disseminated a survey to evaluate the communication factors that affect pilots’ risk perception. In this paper, we evaluate whether different representation methods affect relative risk perception among pilots
