Noise and Time Pressure Effects on Situation Awareness and Aviation Maintenance Tasks

<p>Aircraft maintenance technicians (AMTs) working in a line maintenance work setting are very susceptible to the deafening occupational noise from the airport vicinity or the maintenance machinery itself. Compared to a base maintenance working period, a line maintenance job requires AMTs to complete a task within a short time frame. The current study's objective is to determine if different noise levels and time pressure influence AMTs' performance and situation awareness (SA). Sixteen Embry-Riddle Aeronautical University students majoring in Aviation Maintenance Science participated in a within-subject experimental design. Each participant's performance, SA level, and perceived workload were measured during maintenance tasks in four different environments. The results show that time pressure significantly affects AMTs' performance, SA, and perceived workload. However, the performance, SA, and perceived workload were not significantly affected by the noise levels.</p>
