- 2.
Detonation occurs in a reciprocating aircraft engine when
-
there is an explosive increase of fuel caused by rich fuel/air mixture.
-
The unburned fuel/air charge in the cylinders is subjected to instantaneous combustion.
-
the spark plugs receive an electrical jolt caused by a short in the wiring.
-
The spark plugs are faulty, leading to improper ignition timing.
Correct Answer
A. The unburned fuel/air charge in the cylinders is subjected to instantaneous combustion.Explanation
Explanation: Detonation in a reciprocating aircraft engine occurs when the unburned fuel/air charge in the cylinders is subjected to instantaneous combustion. This means that instead of a controlled and gradual burn, the fuel and air mixture ignites all at once, causing a rapid increase in pressure and temperature. This can lead to engine damage and decreased performance.Rate this question:

Detonation may occur at high-power settings when
-
An excessively rich fuel mixture causes an explosive gain in power.
-
The fuel/air mixture is too lean, leading to incomplete combustion.
-
The fuel mixture ignites instantaneously instead of burning progressively and evenly.
-
The engine's cooling system is not functioning optimally, causing overheating of the cylinders.
Correct Answer
A. The fuel mixture ignites instantaneously instead of burning progressively and evenly.Explanation
When the fuel mixture ignites instantaneously instead of burning progressively and evenly, it can lead to detonation occurring at high-power settings. This means that the fuel ignites too quickly and forcefully, causing a rapid and uncontrolled release of energy within the engine. This can result in damage to the engine components and a loss of power. It is important for the fuel to burn in a controlled and gradual manner to ensure optimal engine performance and prevent detonation.Rate this question:

Airspeed is increased during a level turn, what action would be necessary to maintain altitude? The angle of attack
-
And angle of bank must be decreased.
-
Must be increased or angle of bank decreased.
-
Must be decreased or angle of bank increased.
-
Extend the flaps and pull back on the elevator control.
Correct Answer
A. Must be decreased or angle of bank increased.Explanation
To maintain altitude during a level turn, the airspeed needs to be increased. This can be achieved by decreasing the angle of attack, which refers to the angle between the wing's chord line and the oncoming airflow. Additionally, the angle of bank, which refers to the angle at which the aircraft is tilted in relation to the horizon, may need to be increased to generate the necessary lift. Therefore, the correct answer is that the angle of attack must be decreased or the angle of bank increased.Rate this question:
-
- 5.
At the airspeed represented by point A, in steady flight, the airplane will
-
Have its maximum L/D ratio.
-
Have its minimum L/D ratio.
-
Be developing its maximum coefficient of lift.
-
Experience an increase in lift.
Correct Answer
A. Have its maximum L/D ratio.Explanation
At the airspeed represented by point A, the airplane will have its maximum L/D ratio. The L/D ratio refers to the lift-to-drag ratio, which is a measure of the efficiency of an aircraft. A higher L/D ratio indicates that the aircraft can generate more lift with less drag, resulting in improved fuel efficiency and longer range. Therefore, at the airspeed represented by point A, the aircraft will be operating at its most efficient state, with the maximum L/D ratio.Rate this question:

While maintaining a constant angle of bank and altitude in a coordinated turn, an increase in airspeed will
-
decrease the rate of turn resulting in a decreased load factor.
-
increase the rate of turn resulting in no change in load factor.
-
Decrease the rate of turn resulting in an increased load factor.
-
Decrease the rate of turn resulting in no change in load factor.
Correct Answer
A. Decrease the rate of turn resulting in no change in load factor.Explanation
Explanation: In a coordinated turn, the rate of turn is determined by the angle of bank and the airspeed. When the airspeed increases while maintaining a constant angle of bank and altitude, the increased airflow over the wings generates more lift, which counteracts the centrifugal force and reduces the rate of turn. However, since the load factor is the ratio of the lift to the weight of the aircraft, and the lift remains constant in this scenario, there is no change in the load factor. Therefore, an increase in airspeed will decrease the rate of turn without affecting the load factor.Rate this question:

-
1,320 feet
-
440 feet
-
880 feet
-
440 feet
Correct Answer
A. 1,320 feetExplanation
The altitude that the airplane will lose in 3 statute miles of gliding at an angle of attack of 8° is 1,320 feet.Rate this question:
-

The mixture control can be adjusted, which
-
regulates the amount of airflow through the carburetor's venturi.
-
prevents the fuel/air combination from becoming lean as the airplane climbs.
-
Prevents the fuel/air combination from becoming too rich at higher altitudes.
-
Regulates the amount of airflow through the carburetor's venturi.
Correct Answer
A. Prevents the fuel/air combination from becoming too rich at higher altitudes.Explanation
The mixture control can be adjusted to prevent the fuel/air combination from becoming too rich at higher altitudes. This is important because as an airplane climbs to higher altitudes, the air becomes less dense, leading to a decrease in the amount of oxygen available for combustion. Without adjusting the mixture control, the fuel/air ratio would become too rich, resulting in an inefficient combustion process and potential engine damage. By adjusting the mixture control, the pilot can ensure that the fuel/air combination remains at an optimal level for efficient and safe engine operation at different altitudes.Rate this question:

What effect, if any, would a change in ambient temperature or air density have on gas turbine engine performance?
-
As temperature increases, thrust increases.
-
As air density decreases, thrust increases.
-
As temperature increases, thrust decreases.
-
As temperature decreases, thrusts decreases.
Correct Answer
A. As temperature increases, thrust decreases.Explanation
An increase in ambient temperature affects the performance of a gas turbine engine by reducing the thrust it produces. This is because as the temperature rises, the air becomes less dense, leading to a decrease in the mass flow rate of air entering the engine. With less air available for combustion, the engine is not able to generate as much thrust.Rate this question:

For a given angle of bank, in any airplane, the load factor imposed in a coordinated constant-altitude turn
-
varies with the rate of turn.
-
is constant and the stall speed decreases.
-
Varies with the amount of fuel in the aircraft's tanks.
-
is constant and the stall speed increases.
Correct Answer
A. is constant and the stall speed increases.Explanation
In a coordinated constant-altitude turn, the load factor imposed on the airplane remains constant. The load factor is the ratio of the lift force to the weight of the airplane. As the angle of bank increases, the lift force required to maintain the turn also increases, which in turn increases the stall speed of the airplane. Therefore, the correct answer is that the load factor is constant and the stall speed increases.Rate this question:

The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as
-
instantaneous combustion.
-
pre-ignition.
-
detonation.
-
Fuel surge.
Correct Answer
A. pre-ignition.Explanation
Pre-ignition refers to the uncontrolled firing of the fuel/air charge in advance of normal spark ignition. This can occur when the air/fuel mixture ignites before the spark plug fires, often due to hot spots in the combustion chamber or a buildup of carbon deposits. Pre-ignition can lead to engine knocking, loss of power, and potential damage to the engine components. Instantaneous combustion, detonation, and fuel surge are not accurate descriptions of this phenomenon.Rate this question:

Which airspeed would a pilot be unable to identify by the color coding of an airspeed indicator?
-
The never-exceed speed.
-
The power-off stall speed.
-
The maneuvering speed.
-
Maximum structure cruising speed.
Correct Answer
A. The maneuvering speed.Explanation
The airspeed indicator uses color coding to indicate different airspeeds. The pilot can easily identify the never-exceed speed, power-off stall speed, and maximum structure cruising speed by their respective color codes. However, the maneuvering speed does not have a specific color code on the airspeed indicator. Therefore, a pilot would be unable to identify the maneuvering speed by the color coding on the airspeed indicator.Rate this question:

A detuning of engine crankshaft counterweights is a source of overstress that may be caused by
-
Rapid opening and closing of the throttle.
-
operating with an excessively rich fuel/air mixture.
-
carburetor ice forming on the throttle valve.
-
Excessive oil pressure in the engine.
Correct Answer
A. Rapid opening and closing of the throttle.Explanation
Explanation: Detuning of engine crankshaft counterweights refers to the imbalance or misalignment of the counterweights on the crankshaft, which can cause excessive stress on the engine components. Rapid opening and closing of the throttle can lead to sudden changes in engine speed and load, causing the crankshaft counterweights to become detuned. This can result in increased stress and potential damage to the engine. The other options, such as operating with an excessively rich fuel/air mixture, carburetor ice formation, or excessive oil pressure, do not directly relate to the detuning of crankshaft counterweights.Rate this question:
-
- 14.
Fouling of spark plugs is more apt to occur if the aircraft
-
throttle is advanced very abruptly.
-
descends from altitude with no mixture adjustment.
-
Uses a fuel with a higher octane rating.
-
Gains altitude with no mixture adiustment.
Correct Answer
A. Gains altitude with no mixture adiustment.Explanation
Explanation: When an aircraft gains altitude without adjusting the mixture, the air becomes thinner, which means there is less oxygen available for combustion. This can result in a rich fuel mixture, leading to incomplete combustion and the formation of carbon deposits on the spark plugs, known as fouling. Therefore, the correct answer is that fouling of spark plugs is more apt to occur if the aircraft gains altitude with no mixture adjustment.Rate this question:
-
- 15.
What increase in load factor would take place if the angle of bank were increased from 60° to 80°?
-
4 G's
-
3 G's
-
3.5 G's
-
4.5 G's
Correct Answer
A. 4 G'sExplanation
Increasing the angle of bank from 60° to 80° would result in an increase in the load factor. Load factor is the ratio of the lift force to the weight of the aircraft. When the angle of bank is increased, the lift force must increase to counteract the increased gravitational force acting on the aircraft. This increase in lift force leads to an increase in the load factor. Therefore, the correct answer is 4 G's.Rate this question:
