Which system is NOT overseen by Work Center OE20?

The correct answer identifies a system that is not within the purview of Work Center OE20, which specifically oversees certain operational aspects. Work Center OE20 typically handles systems related to safety and environmental compliance, focusing on equipment and materials that may pose hazards to personnel or the environment.

Safety equipment is crucial for ensuring the protection of personnel and is therefore closely monitored by OE20. ASOS (Automated Surface Observing System) and AFLCS (Automated Flight Landing Control System) are both systems that relate to operational efficiency and safety in aviation contexts, aligning with OE20’s responsibilities.

In contrast, HAZMAT, which refers to hazardous materials management, generally falls under different oversight. While HAZMAT is certainly related to safety in the workplace, it is usually managed by a specialized team focused exclusively on hazardous materials rather than the specific operational focus of Work Center OE20. Thus, identifying HAZMAT as the system not overseen by OE20 aligns with the particular scope and functions of each work center.
