Which of the following is a technique to break the error chain in aviation?

The two-challenge rule is an effective technique to break the error chain in aviation. This rule requires that when a crew member makes a call to another member regarding a critical task or safety issue, the second member must respond not just once, but twice if they believe the call has not been acknowledged or understood. This ensures that critical information is communicated clearly and that any potential misunderstandings are addressed. By enforcing this double-checking mechanism, it significantly reduces the risk of errors that could lead to accidents.

This approach emphasizes the importance of communication and collaboration in a high-stakes environment like aviation, where miscommunication can have serious consequences. The two-challenge rule fosters an environment where crew members feel empowered to speak up and confirm critical information, thus enhancing overall safety.

In contrast, other techniques or choices do not effectively contribute to breaking the error chain. For instance, solo decision-making can isolate a crew member, increasing the likelihood of errors going unchallenged. Ignoring minor issues could allow small problems to escalate into significant consequences. Similarly, minimal communication is detrimental as it reduces the opportunities for verifying important information, potentially leading to misunderstandings and unsafe situations.
