Final answer:
RL 3 NCM aircrew are authorized to fly with other aircrew who are at the same or a higher level of readiness, including RL 2 and RL 3 individuals. They are not limited to flying only with RL 1 aircrew and typically do not fly with civilian pilots or RL 4 aircrew.
Step-by-step explanation:
The question refers to the Readiness Level (RL) system, which is used to determine the qualifications of aircrew within the military aviation community. RL 3 NCM (Non-Commissioned Members) are aircrew at the third level of readiness. As per military training and readiness procedures, RL 3 NCM aircrew are typically authorized to fly with other aircrew that are at the same or a higher readiness level, which would include both RL 2 and RL 3 aircrew. They would not necessarily be restricted to flying with only RL 1 aircrew, which are at the highest state of readiness. Civilian pilots and RL 4 aircrew, who are at the lowest level of readiness, are generally not included within the scope of authorized personnel for RL 3 NCM aircrew to fly with during their training and mission duties.
Answer: B) RL 2 and RL 3 aircrew
