How long will the flight take and how much fuel is required?4 hours; 1700 lbs fuel3.4 hours; 1500 lbs. fuel2.5 hours; 1300 lbs. fuel2.5 hours; 1000 lbs. fuelYou are over KSAT at 8000 feet with an outside temperature of -10 C and 750 pounds fuel when you are diverted to KMAF some 241 nm distant. What power setting is required at 1900 rpm to make the diverted flight to Midland with 45 minute fuel reserve?1658 torq;1500 torq.1300 torq1245 torq.On the PT6A-114A (675 shp), why is it not a good idea to apply maximum takeoff torque of 1865 ft-lbs during takeoff?Upon application of takeoff power, propeller blades will flex forward while overcoming air resistance. Once the propeller blades relax, resistance is minimized and a torque value above 1865 will be realized.The torque meter is a simple gauge grossly affected by temperature and ambient air pressure. Torque values will vary based on existing conditions and an over-torque condition may exist.If engine oil is low, the torque pressure indicator cannot receive a true value and an over-torque condition may exist.The prop governor will restrict the reading on the torque meter and an over-torque condition may exist without ever being seen.An auxilliary fuel boost pump and an ejector pump are both located in the fuel reservoir. Why are their two different styles of pump?If the boost pump fails in flight, the ejector pump will automatically increase fuel pressure to the engine to prevent disruption.Two, different styles of pump insures even fuel flow to the engine.Two, different styles of pump prevent the introduction of air or cavitation in the fuel line.If the engine driven fuel pump fails, the ejector pump will provide the necessary fuel pressure to keep the engine runningDuring shutdown, feathering the propeller and immediately cutting fuel is a very poor and dangerous habit. Why?In any other turbine, such as a Garrett or Walthers, immediately feathering and cutting fuel closes waste gates and prevents the engine from being cooled. Without a necessary cool down time before cutoff, you can fry the turbine.The feathering cycle takes roughly 10 seconds before various oil pressure stabilize. Cutting fuel too soon slows this process.Not allow the propeller to stabilize in feather and cool down, traps heat and increases wear on internal parts.All the answersIf, while in flight, the engine suddenly falls back to idle, what has happened?The throttle tensioner is too loose allowing the throttle to drift back to idle.The fuel control unit has malfunctioned.The fuel reservoir has run dry.The engine driven fuel pump has failed.Time is Up!Time's up Submit a Comment Cancel replyYou must be logged in to post a comment.
