When an aircraft's logbook requires more than one binder, how are they labeled?

When an aircraft's logbook requires more than one binder, they are labeled as volumes. This labeling system helps in organizing and maintaining a clear record of the aircraft's maintenance, inspections, and other important flight-related information. By using volumes, each binder can correspond to a specific period or set of operational details, ensuring that all entries are easy to locate and reference. This system also aids in compliance with regulatory requirements, as it demonstrates thorough and systematic record-keeping practices, which are crucial for both safety and maintenance reliability.

In contrast, labeling by date would not effectively categorize the logbook contents and could lead to confusion if multiple dates span the same binder. Compendium and sections may also imply different organizational structures that are not standard for logbooks, thus reinforcing why volumes are the accepted method for this type of documentation.
