Which is a technique utilized to break the human error chain?

The technique utilized to break the human error chain is the two challenge rule. This method is designed to enhance communication and ensure that instructions are clearly understood within the cockpit or operational environment. By requiring that critical commands or information be challenged twice, it helps to mitigate the risk of misunderstandings that could lead to mistakes or mishaps.

The two challenge rule promotes a culture of safety by encouraging crew members to actively confirm and clarify directives rather than passively accepting them, thus creating a more robust communication framework. This is particularly important in high-stress or high-consequence environments, where the likelihood of error can increase.

Choosing this technique reflects an understanding that human error can occur from miscommunication or assumptions, and by implementing structured challenges, the crew can catch potential issues before they escalate into actions based on flawed information.
