The purpose of the present study was to assess the influence of alarm relevance and reliability on pilots' perceptions of alarm relevance, urgency, importance, how compelled they were to respond, and actual response behavior. Twenty commercial pilots flew a simulated aircraft roundtrip from Dulles airport to Boston Logan airport and responded to 20 pressurization alarms. Each participant experienced alarms that were 60% or 80% reliable and alarms with either high or low relevance. Results indicated that pilots performed established flight procedures regardless of system reliability, though they responded faster and more often to more relevant alarms. These findings suggest that pilots consider alarm relevance when responding to alarms but they are extrinsically compelled to respond to unreliable alarms because of their training. The research supports prior alarm prioritization research. Alarm relevance affects pilots' rate and speed of response, and pilots are influenced by their training to overmatch their alarm responses.
