Threat and Error Management FAQ

Updated: Feb 5, 2023

As a pilot, your ultimate goal is to ensure a safe and successful flight. To achieve this, it is essential to understand the concepts of Threat and Error Management (TEM). In this blog post, we will explore what TEM is, what its components are, and how you can manage errors and threats in aviation.


What is Threat and Error Management Model?

The TEM Model is a framework that helps pilots to identify, assess, and manage threats and errors during all phases of flight. The model provides a systematic approach to handle unexpected events and to help pilots maintain situational awareness, make informed decisions, and take appropriate actions.

What are the 3 components of Threat and Error Management?

1) Threat Detection: The process of identifying potential threats to the flight.

2) Error Detection: The process of recognizing errors made by the flight crew or the aircraft systems.

3) Threat and Error Management: The process of mitigating the identified threats and errors through corrective actions.

How do you manage errors in aviation?

Errors in aviation can be managed by recognizing and addressing them quickly. Pilots should continuously monitor their performance and the performance of the aircraft systems to detect any errors.

When an error is detected, the pilot should evaluate the situation and determine the best course of action to mitigate the error. Additionally, pilots can use standard operating procedures (SOPs) and checklists to help preventing errors from occurring.

What are the 4 types of threats?

1) Internal Threats: Threats that come from within the aircraft, such as equipment malfunctions or crew errors.

2) External Threats: Threats that come from outside the aircraft, such as weather conditions or air traffic control issues.

3) Organizational Threats: Threats that come from organizational factors, such as inadequate training or inadequate maintenance procedures.

4) Environmental Threats: Threats that come from the physical environment, such as turbulence or icing conditions.

What are the 4 methods of threat detection?

1) Monitoring: Continuously monitoring the flight environment to detect potential threats.

2) Anticipation: Anticipating potential threats based on prior experience and knowledge.

3) Checklists: Using checklists to help identify potential threats.

4) Feedback: Receiving feedback from other crew members, air traffic control, or other sources to detect potential threats.

What are the 6 steps of threat modeling?

1) Identify the assets: Determine what needs to be protected.

2) Identify the threats: Determine the potential threats to the assets.

3) Assess the likelihood and impact: Evaluate the likelihood and impact of each threat.

4) Prioritize the threats: Determine which threats require immediate attention.

5) Develop mitigation strategies: Determine how to mitigate the identified threats.

6) Implement and monitor the mitigation strategies: Implement the mitigation strategies and monitor their effectiveness.

What are the different types of threat management?

There are two main types of threat management: reactive and proactive.

Reactive threat management involves responding to threats after they have been identified.

Proactive threat management involves identifying and mitigating threats before they occur.

What is the main principle of error management?

The main principle of error management is to continuously monitor and evaluate the flight environment and to take corrective actions when errors or threats are detected.

This requires a proactive approach to flight safety, where the pilot maintains situational awareness, makes informed decisions, and takes appropriate actions to mitigate any errors or threats.

To effectively manage errors, pilots must also be willing to admit their mistakes, learn from them, and implement changes to prevent similar errors from happening in the future.

It is also essential for pilots to have access to accurate and up-to-date information, as well as the training and resources necessary to make informed decisions in the face of threats and errors.


In conclusion, Threat and Error Management is a critical aspect of flight safety, and it is essential for pilots to understand and implement its concepts. By following the TEM model, identifying potential threats and errors, and taking appropriate actions, pilots can ensure a safe and successful flight.


A crucial tool for TEM is collaboration: Wader Free Logbook provides a platform for pilots to do exactly that, as it allows them to share and analyze threats reported by their peers to improve their application of threat and error management.


By utilizing this resource, pilots can stay up-to-date with the latest threats, learn from each other's experiences, and make informed decisions that enhance their overall flight safety. With Wader Free Logbook, pilots can benefit from a shared wealth of knowledge and take a proactive approach to managing the challenges of flying.
