Which of the following refers to aviators, including pilots and flight surgeons?

The term that refers to aviators, including pilots and flight surgeons, is "Rated Crew Members" (RCM). This designation is used to identify individuals who have received formal training, certification, and are qualified to operate an aircraft or perform duties that require specific aviation-related skills and knowledge. Pilots, for instance, undergo rigorous training to obtain their licenses and ratings, while flight surgeons are medically trained personnel with additional qualifications to assess the health and fitness of aviators and crew members.

In an aviation context, having a rating signifies that an individual is endorsed by a recognized authority to perform specific roles, leading to an increased level of responsibility and capability compared to those without such ratings. This recognition is crucial for maintaining safety and operational effectiveness in flight operations.
