In aviation operations, checklists are primarily designed as "check" lists, emphasizing the importance of verifying the completion of tasks rather than simply serving as reminders or "to-do" lists. The key function of a checklist is to ensure that each critical step of a procedure is completed correctly and in the appropriate sequence. This verification process is crucial for safety and efficiency in aviation, where missing a step can lead to serious consequences.

The term "check" signifies that the user is confirming that a specific task has been completed, thus providing a safeguard against human error. For example, pilots will use checklists during various phases of flight to confirm that all necessary equipment is functioning and that all procedures have been accurately followed. This systematic approach helps maintain operational safety and standardization.

By contrast, other descriptions such as "to-do" lists and "task lists" do not capture this essential aspect of verification. While "to-do" lists imply a collection of tasks that need to be completed, they do not inherently involve confirming that each item has been done.
