Quiz 10 - 25

QuestionAnswer
1. Can an augmenter tube system be controlled by the pilot? Yes No Yes but only if the augmenter is equipped with a variable flow valve Yes but only if the augmenter is equipped with a variable flow valve
2. What is used to drive a supercharger? Belt drive Exhaust gasses Engine crankshaft Engine crankshaft
3. On small aircraft recip engines, fuel vaporization may be increased by. Cooling the air before it enters the engine Circulating fuel & air mixture thru passages in the oil sump Heating the fuel before it enters the carburetor Circulating fuel & air mixture thru passages in the oil sump
4. If muffler baffles become dislodged on a recip engine; what can happen? Carbon dioxide leakage Total exhaust blockage No effect Total exhaust blockage
5. When should cowl flaps be open? Choose all that apply. During engine start During taxi During takeoff During Cruise flight During landing When flying in bad weather During engine start During taxi During takeoff
6. If an alcohol injection system is used as a form of carb de-ice; where is the alcohol injected? Butterfly valve Air filter At entrance to carburetor At entrance to carburetor
7. Alternate air doors... (Finish the statement) Open by the pilot when the main air filter is blocked and allow filtered air into the air induction system. Open by the pilot when the main air filter is blocked and allow unfiltered air into the air induction system. Open automatically when the main air filter is blocked and allow unfiltered air into the air induction system. Open automatically when the main air filter is blocked and allow filtered air into the air induction system. Open automatically when main air filter is blocked and allow unfiltered air into the air induction system
8. Does a turbo-supercharger system require a turbine? Yes No Yes Feedback:Correct: A Turbo-Supercharger system incorporates both an external turbocharger as well as an internal supercharger and, therefore, does require a turbine
9. When the turbocharger waste gate is completely closed; what is happening? All exhaust gasses are going directly out the exhaust. No boost All exhaust gasses are going through the turbo turbine. Full boost No effect on the turbocharger All exhaust gasses are going through the turbo turbine. Full boost
10. What shape are helicopter & APU exhaust tail pipes? Convergent Divergent – Convergent - Divergent Divergent
11. The purpose of an anti-ice system is to remove ice already formed in the induction system. True or False? True False False
12. One source commonly used for carburetor heat is. Turbocharger heated air Alternate air heat Exhaust gasses through a heat exchanger Exhaust gasses through a heat exchanger
13. Ball joints in a recip engine exhaust system should be. Tight enough to prevent movement Disassembled and replaced every inspection Snug but loose enough to allow some movement Snug but loose enough to allow some movement
14. Thrust reversers utilizing a pneumatic actuating system usually receive operating pressure from what source? An on-board hydraulic or electric compressor High pressure air tanks Compressor bleed air Compressor bleed air
15. The purpose of a sonic venturi on a turbocharged equipped aircraft is to. Increase the velocity of the fuel / air charge Increase the amount of air that can flow from the turbocharger into the cabin for pressurization Limit the amount of air that can flow from the turbocharger into the cabin for pressurization Limit the amount of air that can flow from the turbocharger into the cabin for pressurization
16. Where is the hottest point in a gas turbine engine? Exhaust Combustion section First stage turbine inlet nozzle vanes First stage turbine inlet nozzle vanes
17. What method is commonly used to prevent carburetor ice? Mix alcohol with fuel Preheat the intake air using a heat exchanger Electrically heat carburetor venturi and throttle valve Preheat the intake air using a heat exchanger
18. Where, in the system, is carburetor heat located on a fuel injected recip engine? At the air intake None is required Between the air intake and the venturi None is required
19. What shape are most turbofan inlets? Convergent Divergent Convergent - Divergent Divergent
20. How may recip engine exhaust system leaks be detected? An exhaust trail on the airplane exterior Fluctuating manifold pressure Signs of exhaust soot in the vicinity of the leakage Signs of exhaust soot in the vicinity of the leakage
21. On aircraft that utilizes an exhaust heat exchanger as a source of cabin heat, how should the exhaust system be inspected? X-Ray Dye penetrant With the heater shroud removed With the heater shroud removed
22. What is the purpose of a bellmouth inlet on a turboshaft engine? To reduce noise To maximize aerodynamic efficiency of the inlet To improve fuel efficiency To maximize aerodynamic efficiency of the inlet
23. What is a characteristic of a good weld? The weld should build up at least 1/4" A darkened area around the weld The weld should taper off smoothly into the base metal The weld should taper off smoothly into the base metal
24. What is the purpose of an intercooler when used with a turbocharger on a recip engine that uses a carburetor? Cool exhaust gasses before contacting the turbo drive Cool the turbocharger bearings Cool air entering carburetor from the turbocharger Cool air entering carburetor from the turbocharger
25. Why do aircraft use turbochargers? To increase engine fuel economy For anti-ice To maintain higher manifold pressures at higher altitudes compared to naturally aspirated engines. Therefore, increasing the aircraft's critical altitude To maintain higher manifold pressures at higher altitudes compared to naturally aspirated engines. Therefore, increasing the aircraft's critical altitude
