10.52 Threat and Error Management

10.52.2 Explain the role of human error in aviation accidents.

Human error is a significant factor in many aviation accidents.

Pilots, air traffic controllers, and maintenance personnel are all capable of making mistakes that can lead to accidents.

These errors can be caused by a variety of factors, including:

  • fatigue,
  • stress,
  • distraction,
  • poor communication, and
  • inadequate training.


10.52.4 Explain the degree to which human error can be eliminated. 

It's impossible to completely eliminate human error in any industry, including aviation.

However, training, technology, and safety protocols can minimise the likelihood of human error and mitigate the consequences of any errors that do occur.


10.52.6 Describe the main types of threats which could potentially affect a safe flight. 

The main types of threats that could affect a safe flight include:

  • weather conditions,
  • mechanical failures,
  • human error, and
  • security threats.


10.52.8 Explain the basic elements and features of the Reason Model. 

The Reason Model is a framework for understanding how accidents occur.
