Which of the following is not a best practice when using a duty notebook?

Leaving blank spaces for later notes is not considered a best practice when using a duty notebook because it can lead to confusion and inaccuracies in documentation. Best practices emphasize the importance of having a complete and coherent record. A well-maintained duty notebook should provide clear, chronological entries without gaps that may cause important details to be overlooked or misremembered.

Using blue or black pen ensures the visibility and permanency of the notes, maintaining a professional tone reflects the seriousness of documentation, and accurately documenting events helps ensure the integrity and reliability of the recorded information. All these practices contribute to creating a reliable and effective record, whereas leaving blank spaces can compromise the quality of the documentation.
