This survey obtained feedback from 50 commercial pilots on the design characteristics of a set of auditory flight deck alerts. The first section in the online questionnaire assessed pilot views on current loudness levels and prevalence of cognitive impairment from alert presentation. The second section in the questionnaire required the pilots to rate the effectiveness of 10 auditory alerts currently in operation on a large commercial aircraft. In general, the alerts were rated favorably on informational content variables, but unfavorably on presentation style variables. Loud, continuous alerts can distract pilot attention away from processing task-related information, increasing the potential for error. New methods for alert presentation are suggested, based on real-time analysis of flight deck noise. This is argued to offer a more suitable environment for problem solving, decision making, and communication during alert situations.
