What effect does a low workload have on crew members?

A low workload situation typically leads to drowsiness and boredom among crew members. When crew members do not have enough tasks to keep them engaged, their attention can drift, and they may find it difficult to stay alert. This lack of stimulation can cause mental fatigue and a decrease in situational awareness, which can be detrimental in the operating environment of an aircraft.

In aviation, maintaining a high level of vigilance and engagement is essential for safety and efficiency. Crew members need to be actively involved in their tasks and responsibilities to effectively respond to any changes or emergencies that may occur. Low workload can hinder this, leading to a loss of focus and reduced performance, thereby increasing the risk of errors during critical operations. It's important for aircrew to be aware of these effects and take proactive measures to mitigate drowsiness and maintain readiness, especially in environments where situational awareness is paramount.
