MH60T Trivia #126-150

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? 

126. Q: Normal pattern airspeed at the 90? 
A: 70-80 kts. 

127. Q: Transition point defined? 
A: 300′ AGL, 60-70 kts., 1500′-2000′ from touchdown. 

128. Q: Max rate of descent on a steep approach? 
A: 700 fpm, maintaining translational lift as long as possible. 

129. Q: Np in which Np overspeed protection will shut down the engine? 
A: 120. 

130. Q: What is required for a cross-bleed start? 
A: Ng above 90%, engine anti-ice light out, 100% Nr. 

131. Q: Starter drop out normally occurs at? 
A: 52-65% Ng. 

132. Q: Airspeed jettison limit for external tanks (1/3 to full tank)? 
A: 0-120 kts. 

133. Q: Airspeed jettison limit for external tanks (less than 1/3 tank)? 
A: 0-70 kts. 

134. Q: Airspeed jettison limit for external tanks in a descent (1/3 to full tank)? 
A: 0-100 kts. less than 1500 fpm. 

135. Q: Airspeed jettison limit for external tanks in a descent (less than 1/3 tank)? 
A: Avoid. 

136. Q: What are the restrictions when installing/using the 75 or 80 gal. tanks? 
A: Can only carry fuel on the right side, can be ferried empty on the left inboard, not outboard, cannot be jettisoned from the left inboard. 

137. Q: Main fuel tank capacity – JP-5 (6.8 lbs./gal.)? 
A: 590 gals., 4012 lbs. 

138. Q: 120 gal. tank capacity and 113 gal. capacity – JP-5 (6.8 lbs./gal.)? 
A: 816 lbs. and 768 lbs. 

139. Q: 80 gal. tank capacity and 75 gal. tank capacity – JP-5 (6.8 lbs./gal.)? 
A: 544 lbs. and 510 lbs. 

140. Q: Max fuel in tanks before initiating an unmonitored manual fuel transfer? 
A: 3200 lbs. 

141. Q: When will fuel start to transfer with the FMCP in AUTO/TRANSFER? 
A: At 66% capacity of the mains (about 2600 lbs. in the mains). 

142. Q: Max refueling pressure? 
A: 55 psi. 

 143. Q: Which main tank contains the high-level shutoff valve? 
A: Left main. 

144. Q: If the right cell fills faster than the left, when should fueling stop? 
A: 1700 lbs. in right cell, because the shut-off valve in the left cell will not operate properly preventing the high level shut-off valve from working, resulting in an overpressure of the cells due to continued fueling. 

145. Q: Auxiliary tank fill sequence? 
A: LT out, LT in, RT inboard, auto transfer is the opposite. 

146. Q: Normal sequence for auto fuel transfer? 
A: RT, LT inner, LT outer. 

147. Q: Flight regime and fuel level that may result in fuel starvation (engine flameout)? 
A: When balanced flight is not maintained or 15° nose up or down with 300 lbs. or less in either main tank. 

148. Q: Fuel dump rate? 
A: Approximately 800 lbs./min. 

149. Q: Fuel dump stops automatically at? 
A: 210 lbs. right main cell, 270 lbs. left main cell

150. Q: #1 or #2 FUEL LOW indicates how much fuel is left in the cell? 
A: 200-225 lbs.
