What does “checklist usage” refer to in aviation?

Checklist usage in aviation refers to the practice of properly utilizing a systematic list of tasks that pilots must complete to ensure safety and compliance during various phases of flight. The use of checklists is critical for enhancing safety and efficiency in the cockpit, as it helps to standardize procedures, minimize the risk of missed items, and ensure that all necessary tasks are completed in their intended order.

By following a checklist, pilots can manage complex operations and confirm that they have completed critical steps related to pre-flight, takeoff, in-flight, and landing activities. This systematic approach is particularly important during high workload situations, when the risk of overlooking crucial tasks increases.

While communications with air traffic control, adjusting flight controls, and completing pre-flight inspections are all important aspects of aviation procedures, checklist usage specifically focuses on the methodical approach to confirming task completion and operational readiness, which is why this response is the most accurate in defining the term.
