What are the basic components of the Threat and Error Management (TEM) model?

The Threat and Error Management (TEM) model is an essential framework in aviation safety that identifies three fundamental components: threats, errors, and undesired aircraft states. Understanding each component is crucial for managing potential risks in the aviation environment.

Threats are external factors that can negatively impact the safety of a flight, such as adverse weather, traffic congestion, or equipment malfunctions. Errors refer to the mistakes made by crew members, which can arise from various sources including miscommunication, decision-making lapses, or misinterpretation of information. Finally, undesired aircraft states are situations where the aircraft is not in the intended condition or position, which can result from a combination of threats and errors.

The identification of these elements allows flight crews to use countermeasures effectively to mitigate risks and enhance safety. By focusing on threats, errors, and undesired aircraft states, crews can implement strategies to maintain control and prevent incidents. This comprehensive approach helps ensure that safety remains a top priority throughout all phases of flight.
