Define "CRM" in the context of commercial aviation.

CRM stands for Crew Resource Management in the context of commercial aviation. This concept is centered around improving flight safety and efficiency through effective communication, decision-making, and teamwork among cabin crew and flight crews. It emphasizes the importance of using all available resources — personnel, hardware, and information — to promote situational awareness and mitigate errors during flight operations.

CRM was developed in response to the increasing complexity of aviation operations and the recognition that human factors often play a crucial role in aviation safety. By focusing on how crew members interact and collaborate, CRM training aims to enhance crew performance, reduce the likelihood of miscommunication, and foster a culture of safety. This training has become an integral part of pilot and crew education, helping to prepare them for the dynamic and often unpredictable nature of flying.

The other choices mention various interpretations of resource management, but they do not capture the specific focus and historical development of Crew Resource Management as it pertains to safety and teamwork in aviation.
