What ETIMS feature enables TO users to view properly formatted numbered and indexed electronic technical orders?

The correct choice, TO Viewer, is specifically designed to allow users to access electronic technical orders (ETOs) in a format that is both numbered and indexed properly. This feature ensures that users can easily navigate through technical orders, which are crucial for maintaining equipment and safety compliance.

The TO Viewer facilitates a user-friendly interface where users can quickly locate the required technical order, making it an essential tool for personnel who rely on precise and efficient access to technical documentation. Proper formatting and indexing help users find specific procedures and guidelines without sifting through unorganized information, reducing the risk of errors during operations.

In contrast to the other options, which serve different purposes within the ETIMS system, the TO Catalog focuses more on the organization of technical orders rather than their presentation for viewing. The TO Manager relates to the administrative aspects of managing or controlling the technical orders instead of viewing them. The TO Library, although it sounds similar, functions more like a repository of various technical orders rather than a tool specifically designed for formatted viewing.
