How did CRM evolve?

How did CRM evolve?

• A. Developed in the 1970s after human-error accidents; refined by AC 120-51 updates.
• B. Developed in the 1990s with airline mergers.
• C. Created in 1950s as a response to mechanical failures.
• D. Evolved from military training in the 1960s.

Answer: (A)

CRM evolved because aviation recognized that most safety issues originate with people working together in the cockpit, not just with machines. In the 1970s, a string of accidents highlighted how breakdowns in communication, leadership, and decision-making contributed to poor outcomes. The Tenerife disaster of 1977 is a well-known example where crew coordination failures helped drive the need for a human factors approach. This realization led to the development of formal crew training that focused on how pilots, flight engineers, and others could allocate duties, speak up, and rely on one another’s resources. Over the following years, aviation authorities and airlines built structured CRM programs and culminated in guidance that codified what CRM should include. The FAA’s Advisory Circular 120-51 provided the framework and training standards for CRM, and updates to that guidance refined the content to keep pace with evolving practices in human factors, teamwork, and safety culture. This combination—origin in the 1970s due to human-factor-related accidents and subsequent refinement through regulatory guidance—best captures how CRM developed. The other options don’t fit as well because they place CRM’s origin in the wrong era or attribute it to factors that aren’t its primary driver. The idea didn’t arise in the 1990s because of airline mergers, nor did it originate in the 1950s as a reaction to mechanical failures. While there is some influence from military training, the civil aviation CRM evolution centers on the 1970s human-factor accidents and the subsequent FAA guidance.
