Which statement best describes the evolution of CRM definitions?

• A. CRM now includes cabin crews, maintenance personnel, dispatchers, ATC, and others involved in flight operations.
• B. CRM is limited to cockpit crew only.
• C. CRM has nothing to do with human factors.
• D. CRM only applies to large commercial airlines.

Answer: (B)

CRM definitions began as a cockpit-focused concept, aimed at how the people in the flight deck work together—their communication, coordination, and decision-making to manage the aircraft safely. Describing its evolution as still limited to cockpit crew reflects that original emphasis, the starting point from which the idea grew. The other statements push CRM into roles or ideas that aren’t core to the traditional purpose—expanding to cabin crew, maintenance, dispatchers, and ATC, or denying the human-factors link, or restricting CRM by airline size—none of which align with the classic CRM focus or the way the concept has historically been introduced. So, this option best represents the evolution as it began with cockpit crew and the interpersonal dynamics among those directly involved in flying.
