Although both checklists and SRCs are approved, their use must be authorized by whom?

The correct option regarding the authorization for the use of checklists and Source Review Committees (SRCs) is the Type Commander (TYCOM). TYCOMs are responsible for overseeing operational readiness and ensuring that all procedures, including the use of checklists and SRCs, align with the prescribed standards and regulations. The authority of the Type Commander encompasses establishing operational protocols within their assigned area, which includes approving specific procedures necessary for training and operations involving aviation ordnance.

In the broader context, while the Commanding Officer has significant authority over the unit's operations, and the Safety Officer focuses on maintaining safety protocols, the TYCOM holds the overarching responsibility for approving operational procedures spanning multiple commands. Regulatory Boards may set forth guidelines, but implementation and approval at the operational level hinge on the directives from the TYCOM. This ensures that all units adhere to a standardized approach consistent with the Navy's operational framework and safety requirements.
