This is a structure without any internal framework, where the skin carries all of the flight loads. 2. This is a structure that has an internal substructure attached to the aircrafts skin in order to increase the strength of the fuselage. 3. Usually it consists of a vertical stabilizer, the rudder, the vertical stabilizer, and the elevator. 4. A landing gear with a rear-mounted wheel, and the airplanes are sometimes referred to as tailwheel airplanes. 5. A tricycle gear, or a nosewheel airplane. 6. An oleo strut, which uses a piston enclosed in a cylinder with oil and compressed air to absorb the bumps and jolts of landing and taxi operations. 7. The engine and the propeller. 8. The primary purpose is to provide the power to turn the propeller. Engine mounted accessories provide the secondary purposes of generating electrical power, creating a vacuum source for some flight instruments, and to provide a source of heat for the pilot and passengers. The firewall protects the occupants and serves as a mounting point for the engine. 9. 10. In the approved flight manual or pilots operating handbook, markings, placards, or a combination of these. 11. Trim helps minimize your workload by aerodynamically helping you move a control surface, or maintain the surface in a desired position. 12. Reciprocating and turbine. 13. A four-stroke operating cycle. 14. A. Intake: The piston moves away from the cylinder head on the intake stroke, the intake valve opens and the fuel/air mixture is drawn into the combustion chamber. B. Compression: As the piston moves back toward the cylinder head, the intake valve closes and the fuel/air mixture is compressed. C. Power: When compression is almost complete, the spark plugs fire and the compressed mixture is ignited to begin the power stroke. The expanding gases of 17 Monday, February 15, 2016 the controlled burning drive the piston, providing power that rotates the crankshaft. D. Exhaust: The exhaust stroke expels the burned gases form the chamber through the opened exhaust valve. 15. To bring outside air into the engine, mix it with fuel in the proper proportion, and deliver it to the cylinders where combustion occurs. 16. With the throttle and the mixture. The throttle controls engine speed by regulating the amount of fuel and air mixture that flows into the cylinders, while the mixture controls the fuel/air ratio. 17. It mixes the incoming air with fuel and delivers it to the combustion chamber. 18. They are based on the difference in pressure at the venture throat and the air inlet. 19. Lean. 20. You are decreasing the fuel flow to compensate for decreased air density. This can also eliminate engine roughness during runup at high elevation airports. Air density decreases. 21. Lean the fuel/air mixture in order to compensate for the less dense air, and full rich fuel. The mixture will become too lean, which may result in high engine temperatures, which can cause engine wear and even engine failure over a long period of time. 22. Float-type carburetors are susceptible to carburetor icing due to fuel vaporization and decreasing air pressure in the venture. 23. Carb ice reduces the size of the air passage to the engine. This restricts the flow of the fuel/air mixture and reduces power. If enough ice builds up the engine can cease to operate. 24. When intake air temperature is below 21 C (70 F) and the relative humidity is above 80 %. But it is also possible outside of these ranges. 25. A decrease in engine RPM, followed by engine roughness and possible fuel starvation. 26. There is a slight decrease in rpm, followed by an increase in rpm as the ice melts. 27. There will be a slight decrease in rpm and then remain constant. 28. Using carburetor heat enriches the mixture because the heated air is less dense than the outside air that had been entering the engine. 29. Decrease. 18 Monday, February 15, 2016 30. Whenever you reduce engine rpm below the normal operating range for your airplane, or when you suspect the presence of carburetor ice. 31. During takeoffs, or when continuous full power is needed. 32. They are less susceptible to carburetor icing, they consume less fuel, have increased horsepower, lower operating temperatures, and have longer engine life. 33. Magnetos, spark plugs, interconnecting wires, and the ignition switch. 34. It is a self-contained, engine-driven unit that supplies electrical current to the spark plugs, which is completely independent of the aircrafts electrical system. 35. Because this increases safety and reliability of the ignition system and improves engine performance. The dual system results in a slightly higher power output, and if one magneto fails the other is unaffected. 36. During your pre-takeoff check when you turn to individual magnetos you should witness a drop of rpm, but if it is excessive and beyond your airplanes limitations, it could be malfunctioning. 37. The ignition switch ground wire is disconnected. 38. This is an uncontrolled, explosive ignition, and occurs when fuel in the cylinders explodes instead of burning smoothly. 39. If you allow the engine to overheat or if you use an improper grade of fuel. 40. You can lower the nose to increase airspeed and the cooling airflow around the engine, as well as retard the throttle. 41. Preignition occurs when the fuel/air mixture is ignited in advance of the normal timed ignition. 42. You should attempt to lower cylinder temperature by retarding the throttle, enriching the mixture, and/or lowering the nose attitude. 43. Fuel pump and gravity fed systems. 44. Fuel pump system uses an electric fuel pump to provide fuel to the engine driven fuel pump, whereas the gravity fed system does not need an electrical pump to feed fuel to the engine driven pump. 45. Because in cold weather it can freeze and block the fuel lines. And in warm weather , it can flow into the carburetor and stop the engine. 46. Because this prevents moisture from condensing by eliminating air in the tanks. 47. To avoid combustion of the fuel from a spark caused by static electricity. 19 Monday, February 15, 2016 48. This could cause cylinder head and engine temperatures to exceed normal operating limits. 49. Use the next higher grade if approved by the manufacturer. 50. It functions as a lubricant for the engines moving parts, and provides cooling to the engine by reducing friction and removing some of the heat from the cylinders. It also improves engine efficiency by providing a seal between the cylinder walls and pistons. It also carries away contaminants. 51. A clogged oil line. 52. A plugged oil line, a low oil quantity, or a defective temperature gauge. 53. It could result in a loss of power, high oil consumption, and possible engine damage. 54. During take-offs, go-arounds, or any other flight maneuver that combines low airspeed with high power. 55. You can enrich the mixture, reduce the rate of climb, increase airspeed, or reduce power. 56. You may be using too much power with an overly lean mixture. 57. The throttle controls engine power output, as indicated on the manifold pressure gauge, while the propeller control regulates engine rpm. 58. Because it allows you to select the blade angle that provides the most efficient performance. 59. Avoid low rpm settings with high manifold pressure to prevent internal engine stress. An engine-driven alternator. 60. To provide a means of starting the engine, but it also allows limited operation of electrical components such as the radios, without starting the engine. It is also a valuable source of emergency electrical power in case of alternator malfunction. 61. It monitors the electrical current in amperes within the electrical system. 62. This shows that the battery is charging, and the rate at which it is charging. 63. This means that more current is being drawn from the battery than is being replaced. 64. This means that the electrical load is exceeding the output of the alternator, and the battery is helping to supply system power. This could mean the alternator is malfunctioning, or the electrical load is excessive. You should reduce your electrical load to conserve battery power and land as soon as possible. 20 Monday, February 15, 2016 65. Power comes from the electrical system, not the magnetos. 66. Gyroscopic, pitot-static and magnetic. 67. The airspeed indicator, altimeter, and vertical speed indicator. 68. Hg and 15 ºC. Decrease. 69. 70. Decrease. 71. 1.00 in.

This is the normal operating range of the airplane. 80. This is the flap operating range. 81. This is the maximum flap extension speed. 82. This is the stalling speed in at maximum weight in the takeoff position, also known as the power-on stall speed. 83. This is the stalling speed in the landing configuration, also known as the power-off stall speed. 84. VA is maneuvering speed, where you can employ full and abrupt control movement without the possibility of causing structural damage and is not shown on the airspeed indicator. 85. This is the reading you get from the airspeed indicator and does not reflect variations in air density as you climb to higher altitudes. 21 Monday, February 15, 2016 86. This is indicated airspeed corrected for installation and instrument errors. To determine calibrated airspeed, read indicated airspeed and then correct it by using the chart or table in the POH. 87. True airspeed represents the true speed of your airplane through the air. It is calibrated airspeed corrected for altitude and nonstandard temperature. TAS increases with altitude. 88. Groundspeed represents the actual speed of your airplane over the ground. It is true airspeed adjusted for wind. 89. This is the maximum speed when the landing gear is extended. 90.

With a standard atmosphere and the correct altimeter setting. 105. When the altimeter is set to the local pressure setting. 106. This is the height, or vertical distance, above the surface, also known as AGL. 22 Monday, February 15, 2016 107. A one inch change in the altimeter setting equals 1,000 feet of indicated altitude change in the same direction. 108. Pressure is higher and true altitude is higher than indicated altitude. 109. Pressure levels are lower and your true altitude is lower than your indicated altitude. 110. Trend and rate information. 111. It uses static pressure to measure how fast the ambient air pressure is increasing or decreasing. 112. Only the airspeed indicator. 113. All three pitot-static instruments: Airspeed indicator, altimeter, and VSI. 114. The airspeed indicator will slowly decrease to zero. 115.

Rigidity in space and precession. 120. The principle that a wheel spun rapidly will remain in a fixed position in the plane in which it is spinning. 121. This is the tilting or turning of the gyro in response to pressure, which causes slow drifting and minor erroneous indications in gyroscopic instruments. 122. The turn coordinator is electrically powered, and the attitude and heading indications receive power from a vacuum (suction) system, which provides airflow across the gyros. 123.
