Which entity provides the priorities that QC follows?

The correct choice indicates that Production Control provides the priorities followed by Quality Control (QC). This connection between the two roles is critical in aviation and maintenance contexts, as Production Control is responsible for managing and overseeing the production process in a way that ensures efficiency and safety.

Production Control typically assesses operational needs, schedules, and resource allocation, thus setting the priorities for QC to align with the overarching goals of maintenance and safety within the aviation framework. These priorities often include ensuring that maintenance activities meet regulatory standards, are completed on time, and maintain the highest quality, which is crucial for operational readiness and safety.

As such, by analyzing the needs of the operation and directing them toward quality assurance practices, Production Control plays a pivotal role in ensuring that QC is effectively aligned with the mission and operational demands of the unit.
