Greetings, everyone! I am a college student researching automated decision support tools, such as the EICAS (used for monitoring engine status). Our lab is comparing traditional binary alarm technology (BAT), which emits only one signal when system thresholds are exceeded, to likelihood alarm technology (LAT), which emits one of several signals, each being indicative of the actual probability of a problem. LAT is different then graded alarms, such as those that emit warnings for 1000 feet above ground, 500 feet above ground, 100 feet above ground, etc. Emitted LAT alarm signals represent actual probabilities of dangerous conditions based off advanced fault diagnosis algorithms and sensor technologies. For instance, an LAT "caution" signal may represent a 30% probability of there actually being a problem, while a "warning" may indicate 80% probability, and "urgent" representing 99%. The whole point is that LAT emits one of several alarms based on how far alarm thresholds have been violated, allowing pilots to judiciously choose which signals to ignore and which to acknowledge.
Please indicate if you are a pilot, and if not, your knowledge level/experience. Thank you!
1. Which type of alarm system do you think would better preserve pilot attention? That is, which alarm technology would detract less from primary flying tasks?
2. Which type of alarm would you feel more confident in better diagnosing actual problems?
3. Which type of alarm would you trust more?
4. Which type of alarm would create more mental workload while you were simulataneously trying to fly and diagnose problems?
5. Would you rather interact with a binary or likelihood alarm display during free-flight?
6. Which type of alarm do you think results in better pilot decision making?
Thank you so much for your time & participation! These survey results will be used for alarm research that may eventually end up providing pilots with automated decision support tools that fully aid them in an appropriate manner, instead of adding workload.
