What are the two functions provided by the index-type TO?

The index-type Technical Order (TO) serves two primary functions: it shows the revision status of other TOs and helps users determine the distribution of those TOs. This is crucial for maintaining operational efficiency, as it ensures that personnel have access to the most current and relevant technical orders necessary for maintaining and operating aerospace systems.

By displaying the revision status, the index-type TO allows users to quickly identify which TOs have been updated, ensuring that they are always using the latest procedures and information. Additionally, the help in determining distribution means that users can understand who should have access to which TOs based on their tasks and responsibilities. This ensures that information is appropriately disseminated, supporting effective communication and operation within the aircraft armament systems community.
