Study of Aeronautical Decision Making in Simulated Non-Normal Flight Deck Environment

The Situational Awareness Assessment Technology and NASA-TLX were used to assess the participants’ situation awareness and workload after each experiment. An in-depth interview was conducted after the experiment to understand the subjective perception of each model. The result of the experiment shows CLEAR has the highest SA and lowest workload. The time to solve the emergency issue was shorter than the others model. The DECIDE model increased workload by simultaneously processing lots of information and measuring significant changes, whilst the DOGAM model encouraged participants to make aggressive decisions, leading to increase stress.
