Situational Awareness and Threat and Error Management (SA & TEM)

This module delves into two critical pillars of modern aviation safety: Situational Awareness (SA) and Threat and Error Management (TEM). Understanding and effectively applying these concepts is paramount for pilots operating in multi-crew environments, forming a core component of Crew Resource Management (CRM) and Multi-Crew Cooperation (MCC).

Situational Awareness (SA)

Situational Awareness refers to the accurate perception of the elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the near future. In aviation, it's about knowing what's happening around you, understanding its implications, and anticipating what might happen next.

What are the three levels of Situational Awareness according to Endsley's model?

Perception, Comprehension, and Projection.

Maintaining SA is crucial for safe flight operations. Factors that can degrade SA include fatigue, stress, workload, distractions, and complacency. Effective communication and teamwork within the cockpit are vital for sharing and maintaining SA among crew members.

Threat and Error Management (TEM)

Threat and Error Management (TEM) is a proactive safety concept that focuses on identifying potential threats and managing errors before they can compromise flight safety. It's a systematic approach to aviation safety that acknowledges that threats and errors are inherent in complex operations and provides a framework for managing them.

The TEM model can be visualized as a continuous cycle. Threats are identified and managed, which can lead to errors. Errors are then managed to prevent them from resulting in an undesired aircraft state. Effective SA is foundational to both threat identification and error detection. The interplay between SA and TEM is crucial for maintaining safe flight operations.

High workload, fatigue, and complacency are significant threats to both Situational Awareness and effective Error Management. Crew members must actively work to mitigate these internal threats.

Interplay between SA and TEM

Situational Awareness and Threat and Error Management are intrinsically linked and mutually reinforcing. A strong SA allows pilots to identify potential threats early and accurately. This early identification enables proactive threat management. Similarly, effective error management relies on pilots having a clear understanding of the current situation (SA) to recognize when an error has occurred or is about to occur, and to implement appropriate corrective actions.

In a multi-crew environment, effective communication is the glue that binds SA and TEM. Crew members must openly share their perceptions, understandings, and concerns to build a shared SA. This shared SA then facilitates collaborative threat and error management, ensuring that all crew members are working towards the common goal of safe flight.

How does good Situational Awareness contribute to effective Threat and Error Management?

Good SA allows for early identification of threats and recognition of errors, enabling proactive management and correction.

Practical Application in the Cockpit

Pilots can enhance their SA and TEM skills through continuous training, debriefings, and a commitment to open communication. Practicing techniques like 'read-back' for clearances, 'cross-check' of instruments, and 'brief-back' for procedures reinforces these critical safety concepts. Understanding the potential for automation bias and maintaining vigilance over automated systems is also a key aspect of modern SA and TEM.
