Which of the following is NOT a non-rated crew member?

The choice of a Flight Surgeon as not being a non-rated crew member is correct because a Flight Surgeon typically has a specific role that covers medical oversight for the crew and passengers, which often requires specialized certifications and ratings. Flight Surgeons are usually licensed medical professionals, often with aviation medicine training, who actively participate in the decision-making processes regarding flight safety from a health perspective.

In contrast, non-rated crew members like Flight Medics and Crew Chiefs perform important functions on the aircraft but do not require specific FAA ratings or licenses to carry out their responsibilities as part of the crew. Flight Instructors also typically hold a commercial pilot certificate with instructional privileges, depending on their qualifications, making them rated crew members. This distinction highlights the varying levels of training and certification across different roles within an aviation context, emphasizing the specialized nature of a Flight Surgeon’s qualifications compared to other crew members.
