What action does posting a supplement involve?

Posting a supplement involves adding or updating existing information in reverse numerical order because this practice ensures that the most current information is easily accessible and stands out among older data. By organizing supplementary content in reverse numerical order, it allows users to quickly identify and reference the latest updates, thus promoting efficiency and accuracy in operational procedures.

This method is particularly significant in environments where accuracy and compliance with updated regulations are critical, as it embeds the latest modifications prominently within the set of technical orders. This systematic approach helps prevent confusion that could arise from having older information presented alongside new updates.
