What does Threat and Error Management (TEM) primarily focus on?

Threat and Error Management (TEM) primarily focuses on the relationship between safety and human performance. This concept recognizes that in aviation, the interaction between various threats (such as environmental factors, technical malfunctions, or human factors) and human errors can contribute to safety risks. TEM provides a framework for pilots and crew to identify, assess, and mitigate these threats and errors before they lead to incidents or accidents.

By emphasizing the need for awareness, communication, and proactive decision-making, TEM enhances overall safety by fostering a culture where crew members can operate more effectively and manage unforeseen situations. The approach prioritizes understanding how human performance can be optimized, especially under pressure or in complex operational environments.

Other choices, while important aspects of aviation, do not directly align with the core focus of TEM. The mechanics of flight operations pertain more to technical skills and maneuvers, the design of aircraft systems involves engineering considerations, and the structure of aviation regulations relates to compliance and legal frameworks rather than the direct management of threats and errors in flight contexts.
