6. Workload Assessment Tool Description The Air Traffic Workload Input Technique (ATWIT; Stein, 1985) measures mental workload in “real-time” by presenting auditory and visual cues that prompt a controller to press one of seven buttons on the workload assessment keypad (WAK) within a specified amount of time to indicate the amount of mental workload experienced at that moment. The ATWIT tool has been developed and has been in use at the FAA Technical Center. Evaluation “While controllers showed some initial reluctance to use the ATWIT system, they all managed to integrate it into their behavioral repertoire during training. The task did add somewhat to their workload; but during interviews, they indicated that ATWIT responses became easier to accomplish with training. Most indicated that if they missed a response, it was because they were completely occupied (Stein,1985).” Stein, E.S. (1985). Air traffic controller workload: An examination of workload probe.(Report No. DOT/FAA/CT-TN84/24). Atlantic City, NJ: Federal Aviation Administration Technical Center.

7. NASA Task Load Index Description NASA-TLX is a subjective, post-hoc workload assessment tool. NASA-TLX allows users to perform subjective workload assessments on operator(s) working with various human-machine systems. NASA-TLX is a multi-dimensional rating procedure that derives an overall workload score based on a weighted average of ratings on six subscales. The subscales include Mental Demands, Physical Demands, Temporal Demands, Own Performance, Effort and Frustration. Hart, S.G., & Staveland, L.E. (1988).
