Which prefix corresponds to a formal training instructor?

• A. X - Basic qualified crewmember
• B. K - Aircrew instructor
• C. T - Formal training instructor
• D. Q - Evaluator

Answer: (C)

The important idea is recognizing prefixes that designate a specific training role. The prefix for a formal training instructor is the one tied to delivering structured, officially sanctioned courses: it implies designing and teaching the formal curriculum, following a set syllabus, and conducting formal assessments to certify trainees. This is different from a basic qualified crewmember, who is simply qualified to operate; or an aircrew instructor, who teaches but not necessarily within formalized course structures; or an evaluator, who focuses on judging performance rather than delivering instruction. So the prefix that signals formal training instruction is the one associated with running official training programs and certifying completion.
