8308 During starting of a turbine power plant using a compressed air starter, a hung start occurred. Select the proper procedure:
A. Shut off the fuel
B. Re-engage the starter
C. Shut down the engine.
C
A hung start of a turbojet engine is a start in which the engine lights off as it should, but does not accelerate to a speed that allows it to operate without help from the starter. Anytime a hung start occurs, the engine should be shut down and the cause of the problem found and corrected.
(AM,I,F,K5) (8083-30)
60
8309 A hung start in a jet engine is often caused by:
A. Malfunctions in the ignition system.
B. The starter cutting off too soon.
C. An excessively rich air-fuel mixture.

8315 If a radial engine has been shut down for more than 30 minutes, the propeller should be rotated through at least 2 revolutions to:
A. Check for hydraulic lock
B. Check for leaks
C. Prime the engine
A
A radial engine that has been shut down for some time should be turned through by hand for at least 2 revolutions to check for a hydraulic lock. A hydraulic lock is a condition in a reciprocating engine in which oil has leaked past the piston rings into a cylinder below the center of the engine. If the engine fires when there is oil in any of its cylinders, it will sustain major structural damage.

63
8316 The priming of a fuel injected horizontally opposed engine is accomplished by placing the fuel control lever in the:
A. IDLE CUTOFF position
B. AUTO-RICH position
C. FULL-RICH position
C
When starting a horizontally opposed aircraft engine equipped with a fuel-injection system, prime the engine by placing the mixture control in the FULL-rich position and turning on the fuel boost pump until there is an indication of fuel flow on the flow meter. After some fuel has flowed through the injector nozzles, the mixture control is returned to the IDLE-CUTOFF position and the engine is started. As soon as the engine starts, the mixture control is again placed in the FULL-RICH position.
(AM. I.F.K5) 8083-30
64
8317 The most important condition to be monitored during start after fuel flow begins in a turbine engine is the:
A. EGT, TIT or ITT
B. RPM
C. Oil Pressure

If a hot start occurs during starting of a turbine power plant, what is the likely cause?
A. The starting unit overheated.
B. The ambient air temperature was too high (over 100°F).
C. The air-fuel mixture was excessively rich.
C
A hot start of a turbojet engine is one in which the engine starts normally but the exhaust-gas temperature exceeds its allowable limits. Hot starts are usually caused by too rich a air-fuel mixture. (There was too much fuel for the amount of air being moved through the engine by the compressor.)
(AM.I.F.K5) - FAA-H-8083-30
72
8327. Weather vaning tendency is greatest when taxiing:
A-both nose wheel and tail wheel-type airplanes in a quartering tailwind.
B-a tail wheel-type airplane in a direct crosswind.
C-a nose wheel-type airplane in a quartering
headwind.
B
Weather vaning tendency is more prevalent in the tail wheel- type because the airplane's surface area behind the main landing gear is greater than in nose wheel-type airplanes. The tendency of a tail wheel-type airplane to weather vane is greatest while taxiing directly crosswind. It is difficult to prevent the airplane from turning into any wind of considerable velocity since the airplane's rudder capability may be inadequate to counteract the crosswind.
(AM.I.F.K5) - FAA-H-8083-30
73
8328
When taxiing an airplane with a quartering tailwind, the elevators and:
A. Upwind aileron should be held in the up position.
B. Upwind aileron should be held in the down position.
C. Both ailerons should be kept in the neutral position.
B
When taxiing with a quartering tailwind, the elevator should be held in the DOWN position, and the upwind aileron, DOWN. Since the wind is striking the airplane from behind, these control positions reduce the tendency of the wind to get under the tail and the wing and to nose the airplane over.
(AM.I.F.K5) - FAA-H-8083-30
74
8329
When taxiing (or towing) an aircraft, a flashing red light from the control tower means
A. Stop and wait for a green light.

A-the tail rotor.
B-the main rotor.
C-blowing dust or debris caused by rotor down wash.
A
When approaching or leaving a helicopter whose engine is running, you should remain within the pilot's field of vision to avoid an encounter with the tail rotor.
(AM.I.F.K5) - FAA-H-8083-30
76
8333. When stopping a nose wheel-type airplane after taxiing, the nose wheel should be left:
A-unlocked and pointed straight ahead.
B-turned at a small angle towards uphill if the parking area is not perfectly flat.
C-pointed straight ahead.
C
When stopping an airplane that is equipped with a nose wheel, the nose wheel should be left straight ahead to relieve any strain on the nose gear and to make it easier to start moving straight ahead.
(AM.I.F.K5) - FAA-H-8083-30
77
8334. When first starting to move an aircraft while taxiing, it is important to:
A-test the brakes.
B-closely monitor the instruments.
C-notify the control tower.
A
When first starting to taxi an airplane, test the brakes for proper operation. If braking action is unsatisfactory, the engine should be shut down immediately.
(AM. I.F.K5) - FAA-H-8083-30
78
8340
Characteristics of detonation are:
A. Cylinder pressure remains the same, excessive cylinder head temperature, and a decrease in engine power.
B. Rapid rise in cylinder pressure, excessive cylinder head temperature, and a decrease in engine power.
C. Rapid rise in cylinder pressure, cylinder head temperature normal, and a decrease in engine power.
B
Detonation is an uncontrolled burning, or explosion, of the air-fuel mixture within the cylinder of a reciprocating engine. The air-fuel mixture ignites and burns normally. But as it burns, it compresses and heats the mixture ahead of the flame front. When the heated and compressed mixture reaches its critical pressure and temperature, it releases its energy almost instantaneously (it explodes). It is the explosions inside the cylinder that cause the cylinder-head temperature to go up, the cylinder pressure to go up, and the engine power to decrease.
(AM.I.F.K5) - FAA-H-8083-30
79
8313. Which of the following is the most satisfactory extinguishing agent for use on a carburetor or intake fire?
A-Dry chemical.
B-A fine, water mist.
C-Carbon dioxide.
C
Carbon dioxide (CO2) is the most satisfactory fire extinguishing agent to use for putting out an induction system fire in an aircraft engine. CO2 does not damage the engine, and it does not leave any residue to clean up.

80
8324. What effect, if any, will aviation gasoline mixed with jet fuel have on a turbine engine?
A-No appreciable effect.
B- The tetraethyl lead in the gasoline forms deposits on the turbine blades.
C- The tetraethyl lead in the gasoline forms deposits on the compressor blades.
B
Many aviation gas turbine engine manufacturers allow the use of some aviation gasoline as a fuel when turbine fuel is not available. The manufacturer limits the amount of time aviation gasoline can be used for two reasons:
(1) The tetraethyl lead in the aviation gasoline causes deposits to form on the turbine blades. (2) Aviation gasoline does not have the lubricating properties of kerosine. Using too much gasoline can cause excessive wear on the fuel control.
(AM.I.F.K9) - FAA-H-8083-30
81
8325. (1) Jet fuel is of higher viscosity than aviation gasoline and therefore holds contaminants more readily.
(2) Viscosity has no relation to contamination of fuel.
Regarding the above statements,
A-only 1 is true.
B-both 1 and 2 are true.
C-neither 1 nor 2 is true.
A
Statement 1 is true. Jet fuel has a higher viscosity than gasoline and it holds contaminants more readily (better) than gasoline. Statement 2 is not true. Viscosity does have a great deal to do with the fact that jet fuel holds more contaminants than gasoline. The higher the viscosity, the fewer contaminants will settle out of the fuel.
(AM.I.F.K9) - FAA-H-8083-30
82
8335
The color of 100LL fuel is:
A. Blue.
B. Colorless or straw.
C. Red.
A
Low-lead 100-octane aviation gasoline is dyed blue.
Turbine fuel is normally colorless or straw colored.
Grade 8O aviation gasoline is dyed red.
(AM.I.F.K9)- FAA-H-8083-30
83
8336. How are aviation fuels, which possess greater antiknock qualities than 100 octane, classified?
A - According to the milliliters of lead.
B - By reference to normal heptane.
C - By performance numbers.
C
Aviation fuel whose antidetonation characteristics are better than those of the reference fuel (100-octane) are rated in performance numbers.
(AM.I.F.K9)- FAA-H-8083-30
84
8338
Both gasoline and kerosene have certain advantages for use as turbine fuel. Which statement is true in reference to the advantages of each?
A. Kerosene has a higher heat energy/value per unit weight than gasoline.
B. Gasoline has a higher heat energy/value per unit volume than kerosene.
C. Kerosene has a higher heat energy/value per unit volume than gasoline.
C
Gasoline has a higher heat energy per pound than kerosine (nominally 20,000 Btu per pound for gasoline versus about 18,500 Btu per pound for kerosine). Kerosine, however, weighs more than gasoline (about 6.7 pounds per gallon for kerosine compared with about 6.0 pounds per gallon for gasoline). Because there are more pounds of kerosine per gallon, there are more Btu's in a gallon of kerosine than in a gallon of gasoline.
(AM.I.F.K9)- FAA-H-8083-30
85
8339. What must accompany fuel vaporization?
A-An absorption of heat.
B-A decrease in vapor pressure.
C-A reduction in volume.
A
When fuel changes from a liquid into a vapor, it absorbs heat from the surrounding air. This absorption of heat drops the temperature of the air enough that moisture can condense out and freeze. This is the main cause of carburetor ice.
(AM.I.F.K9)-FAA-H-8083-30
86
8341
A fuel that vaporizes too readily may cause
A. Hard starting.
B. Detonation.
C. Vapor lock.
C
If a fuel vaporizes too readily, it has a high vapor pressure. It requires a high pressure to keep the vapors in the fuel. Vapors that form in a fuel line can prevent liquid fuel flowing through the line and can stop the engine because of fuel exhaustion. This is a vapor lock.
(AM.I.F.K9) - FAA-H-8083-30
87
8342.
Jet fuel number identifiers are:
A. Performance numbers to designate the volatility of the fuel.
B. Performance numbers and are relative to the fuel's performance in the aircraft engine.
C. Type numbers and have no relation to the fuel's performance in the aircraft engine.
C
Jet engine fuel identification numbers (JP-4, JP-5, Jet A, Jet A 1, and Jet B) are identification numbers only and do not relate in any way to the performance of the fuel in the engine.
(AM.I.F.K9) - FAA-H-8083-30
88
8343
The main differences between grades 100 and 100LL fuel are:
A. Volatility and lead content.
B. Volatility, lead content, and color.
C. Lead content and color.
C
The main difference between grades 100 and 100LL aviation gasoline is the content of tetraethyl lead and the color. Their antiknock characteristics are the same. Grade 100 is allowed to have a maximum of 3.0 milliliter of TEL per gallon, and it is dyed green. Grade 100LL is allowed to have a maximum of 2.0 milliliter of TEL per gallon, and it is dyed blue.
(AM.I.F.K9) - FAA-H-8083-30
89
8344
Characteristics of aviation gasoline are:
A. High heat value, high volatility.
B. High heat value, low volatility.
C. Low heat value, low volatility.
A
Aviation gasoline is suitable as a fuel for reciprocating engines because it has a high heat value (nominally 20,000 Btu per pound) and a high volatility. It readily changes from a liquid into a vapor so that it can be burned.
(AM.I.F.K9) - FAA-H-8083-30
90
8346
A fuel that does not vaporize readily enough can cause
A. Vapor lock.
B. Detonation.
C. Hard starting.
C
An ideal fuel for an aircraft reciprocating engine must vaporize (change from a liquid into a vapor) easily, yet it must not vaporize so easily that it will form vapor locks in the fuel system. Liquid fuel will not burn, so for it to burn, it must be changed into a fuel vapor. If the fuel does not vaporize readily enough, it will cause the engine to be hard to start.
(AM.I.F.K9) - FAA-H-8083-30
91
8337 Why is ethylene dibromide added to aviation gasoline?
A. To remove zinc silicate deposits from the spark plugs.
B. To scavenge lead oxide from the cylinder combustion chambers.
C. To increase the antiknock rating of the fuel.
B
Tetraethyl lead is added to aviation gasoline to improve its antidetonation characteristics (to raise its critical pressure and temperature), but deposits left inside the cylinders from the tetraethyl lead foul spark plugs and cause corrosion. In order to get rid of the residue from the tetraethyl lead, ethylene dibromide is mixed with the gasoline. When the gasoline burns, the ethylene dibromide combines with the lead and forms volatile lead bromides that go out the exhaust and do not form solid contaminants inside the cylinder.
(AM.I.F.K10)-FAA-H-8083-30
92
8345
Tetraethyl lead is added to aviation gasoline to
A. Retard the formation of corrosives.
B. Improve the gasoline's performance in the engine.
C. Dissolve the moisture in the gasoline.
