MH60T Trivia #76-100
This trivia series distills over 20 years of flight manual study into 500+ focused questions and answers, posted in 25 question sets. It’s not a substitute for the manual, but rather an aid to facilitate study and strengthen airmanship. During your review, ask yourself: How is this operationally relevant? Do I need to memorize it, or just be familiar with it? Should I review more on this topic?
