What does task loading measure in human factors?

• A. The mental and physical workload, with higher loading associated with more errors
• B. The speed of task completion
• C. The number of tasks to perform in a shift
• D. The financial cost of task performance

Answer: (A)

Task loading in human factors refers to the mental and physical workload placed on an operator. It captures how demanding a task is on attention, working memory, perception, and physical effort. As loading increases, the likelihood of errors rises because cognitive and perceptual resources become strained and decision accuracy can decline under time pressure or fatigue. This concept is about the demands of the task, not simply how fast you complete it, how many tasks exist, or the cost involved. In aviation, measuring task loading helps designers keep workload within safe limits by shaping procedures, interfaces, and automation to reduce excessive demands.
