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?

95. Q: What nose attitude/altitude levels result in stab/tail bumping? 
A: 13° nose up, 15 feet or below. 

96. Q: How much should the collective be raised before moving the PCLs to idle? 
A: A maximum of 1″ from the hand grip to reduce droop stop pounding. 

97. Q: Why can’t you raise the collective after the PCLs are moved to idle? 
A: Damage to anti-flaps. 

98. Q: How long must you cool the engine before shutdown? 
A: 2 mins with Ng below 90% to prevent compressor rotor damage. 

99. Q: If you don’t properly cool the engine what are the time limits for starting the engines? 
A: Restart within 5 mins or wait 4 hours. 

100. Q: Practice autorotation speed range? 
A: 75-95 kts.
