When should automation procedures be preferred over nonautomation procedures?

Automation procedures should be preferred over nonautomation procedures when workload, communications, and equipment capabilities permit because these factors directly influence efficiency and safety in operations. When the complexity of the task is high or the volume of tasks is substantial, automation can help streamline processes, reduce human error, and allow for more consistent execution of procedures.

In situations where communication systems are robust and equipment is functioning optimally, automation can enhance the overall performance and management of the workflow. For instance, during peak operational times or when complex decisions need to be made rapidly, automation systems can assist in handling increased data loads and executing decisions faster than a human could manage alone.

The other options, while they may suggest scenarios that could be accompanied by automation, do not specifically tie the choice to the operational capabilities and conditions that are essential for effective automation implementation. Therefore, the preference for automation stems from a broader consideration of how best operations can be conducted given the resources and situational factors available.
