What does it indicate if crew members ask questions about a new procedure being introduced?

When crew members ask questions about a new procedure being introduced, it indicates that they show interest in the explanation. This engagement is a positive sign, as asking questions often reflects a desire to understand the new information better and ensure successful implementation of the procedure. It demonstrates that the crew members are actively processing the information and seeking clarification on aspects that may not be entirely clear, which can lead to improved performance and safety in their work.

The other options may suggest different attitudes or needs, but they do not capture the essence of the crew's behavior in this scenario as effectively as showing interest. Crew members who are confused might not ask questions at all or may not express their confusion explicitly. Similarly, simply requiring more training does not inherently indicate interest, as it may reflect a lack of readiness to adopt the new procedure. However, questions imply an active engagement and a proactive effort to understand and integrate the new procedure into their workflow.
