Aviation Resource Management Block I Practice Exam

In this topic, a rated aircrew member is someone who holds a flight rating and is authorized to perform flight duties as part of the aircraft’s crew. Pilots clearly fit this definition because they operate the aircraft. An observer also participates in flight-related tasks and, in many aircrew structures, is considered part of the trained flight crew. A flight surgeon accompanies the crew to provide medical support and monitor crew health during flight, which is an onboard role tied to the mission’s safety and execution. All of these are tied to performing tasks that involve operating or supporting the aircraft in flight.

A payload specialist, however, focuses on operating experiments or payloads carried on the mission rather than piloting or directly supporting the aircraft’s flight operations. They are not part of the aircraft’s rated flight crew and do not hold a flight rating to operate the aircraft, which is why they’re not listed as a rated aircrew member.
