Spoilers are devices fitted to the wing, which increase ______ is decrease______.
- A.
Drag, lift.
- B.
Lift, drag.
- C.
Weight, lift.
- D.
Speed, drag.
Correct Answer
A. Drag, lift.Explanation
Spoilers are devices fitted to the wing, which increase drag and decrease lift. When spoilers are deployed, they disrupt the airflow over the wing, creating more drag and reducing the lift generated by the wing. This is useful in situations where the aircraft needs to reduce speed or descend rapidly. By increasing drag and decreasing lift, spoilers help to control and stabilize the aircraft's flight.Rate this question:

An aircraft will stall at any airspeed or attitude if the _________ is exceeded.
- A.
Critical angle of attack.
- B.
Center of gravity.
- C.
Best lift / drag ratio.
- D.
Best angle of climb.
Correct Answer
A. Critical angle of attack.Explanation
An aircraft will stall at any airspeed or attitude if the critical angle of attack is exceeded. The critical angle of attack is the angle at which the airflow over the wings becomes disrupted, causing a loss of lift and an increase in drag. When this angle is exceeded, the aircraft will lose its ability to maintain level flight and will enter a stall condition. The other options, center of gravity, best lift/drag ratio, and best angle of climb, are not directly related to stalling.Rate this question:

- A.
Size and position of the horizontal stabilizer, the position of the C of G.
- B.
Dihedral, the position of the C of G.
- C.
Sweepback, the position of the C of R.
- D.
Keel effect, the position of the fin.
Correct Answer
A. Size and position of the horizontal stabilizer, the position of the C of G.Explanation
The correct answer is the size and position of the horizontal stabilizer, and the position of the center of gravity (C of G). Longitudinal stability refers to the stability of the aircraft around its lateral axis, also known as pitch stability. The size and position of the horizontal stabilizer play a crucial role in maintaining this stability by providing the necessary aerodynamic forces. Additionally, the position of the center of gravity affects the longitudinal stability as it determines the balance of the aircraft.Rate this question:

The only pitot static instrument that requires both a pitot pressure source and a static pressure source is the ______.
- A.
Vertical speed indicator.
- B.
Airspeed indicator.
- C.
Altimeter.
- D.
Attitude indicator.
Correct Answer
B. Airspeed indicator.Explanation
The airspeed indicator is the only pitot static instrument that requires both a pitot pressure source and a static pressure source. The pitot pressure is used to measure the dynamic pressure of the airspeed, while the static pressure is used as a reference to measure the static pressure of the atmosphere. This combination of pressures allows the airspeed indicator to accurately display the aircraft's airspeed. The vertical speed indicator uses only the static pressure source, while the altimeter and attitude indicator use only the pitot pressure source.Rate this question:

Induced drag _______ as the speed of an aircraft increases.
- A.
Decreases
- B.
Remains the same.
- C.
Increases.
- D.
None of the above.
Correct Answer
A. DecreasesExplanation
As the speed of an aircraft increases, the induced drag decreases. Induced drag is caused by the generation of lift, and at higher speeds, the wings create more lift with less drag. This is because the higher speed allows the aircraft to generate lift more efficiently, reducing the amount of drag produced. Therefore, as the speed increases, the induced drag decreases.Rate this question:

The tendency of an airplane in flight to remain in straight, level, upright flight and return to this attitude if displaced without the corrective action of the pilot is called _____.
- A.
Balance.
- B.
Equilibrium.
- C.
Acceleration.
- D.
Stability.
Correct Answer
D. Stability.Explanation
Stability refers to the tendency of an airplane in flight to maintain its straight, level, and upright flight. It also means that the airplane will naturally return to this attitude if it is displaced from its original position. This characteristic is crucial for safe and controlled flight, as stability allows the pilot to have better control and maneuverability of the aircraft.Rate this question:

When thrust and drag are equal and opposite, the airplane is said to be in a state of _____.
- A.
Balance.
- B.
Equilibrium.
- C.
Acceleration.
- D.
Stability.
Correct Answer
B. Equilibrium.Explanation
When thrust and drag are equal and opposite, the airplane is said to be in a state of equilibrium. Equilibrium refers to a state of balance where all forces acting on an object are balanced, resulting in no net force and no change in motion. In this case, the equal and opposite forces of thrust (generated by the engines) and drag (resistance caused by the motion of the airplane through the air) cancel each other out, creating a state of equilibrium.Rate this question:

As air passes over the wing towards the trailing edge, the air moves not only rearward but downward as well. this downward flow is called _______.
- A.
Drag.
- B.
Assymetric thrust.
- C.
Downwash.
- D.
Down flow.
Correct Answer
C. Downwash.Explanation
As air passes over the wing towards the trailing edge, it not only moves rearward but also downward. This downward flow of air is known as downwash. Downwash is an important concept in aerodynamics as it affects the lift and stability of the aircraft. It is caused by the pressure difference between the upper and lower surfaces of the wing, resulting in a downward deflection of the air.Rate this question:

If an aircraft is rolling to the right, aileron drag will cause the aircraft to yaw to the _____.
- A.
Left.
- B.
Right.
- C.
No adverse yaw will be present.
- D.
None of the above.
Correct Answer
A. Left.Explanation
When an aircraft is rolling to the right, aileron drag will cause the aircraft to yaw to the left. This is because the downward deflected aileron on the right wing increases the drag on that wing, which causes it to slow down and generate less lift compared to the left wing. As a result, the aircraft yaws to the left due to the imbalance in lift and drag between the wings.Rate this question:

To relieve back stick pressure in a nose high attitude the trim tab must be in the _______ position.
- A.
Up.
- B.
Neutral.
- C.
Retracted.
- D.
Down.
Correct Answer
D. Down.Explanation
To relieve back stick pressure in a nose high attitude, the trim tab must be in the down position. This is because the trim tab helps to balance the control forces on the aircraft. When the nose of the aircraft is pitched up, there is increased back stick pressure, meaning the pilot needs to exert more force to keep the nose level. By moving the trim tab down, it creates a downward force that helps to counteract the back stick pressure, making it easier for the pilot to maintain control and relieve the pressure on the back stick.Rate this question:

As an aircraft climbs and altitude increases, the stalling speed (IAS) of an aircraft _______.
- A.
Remains the same.
- B.
Increases.
- C.
Decreases.
- D.
Depends on the indicated airspeed.
Correct Answer
A. Remains the same.Explanation
As an aircraft climbs and altitude increases, the stalling speed (IAS) of an aircraft remains the same. This is because the stalling speed is primarily determined by the angle of attack, which is the angle between the wing's chord line and the oncoming airflow. Altitude does not directly affect the angle of attack, so the stalling speed remains constant. However, it is important to note that the true airspeed (TAS) does increase with altitude due to the decrease in air density, but this does not affect the stalling speed.Rate this question:

The propeller usually rotates clockwise as seen from the pilots seat. The reaction to the spinning propeller causes the aircraft to rotate counter clockwise to the left. This left turning tendency is refered to as ______.
- A.
Asymmetric thrust.
- B.
Slipstream.
- C.
Torque.
- D.
Precession.
Correct Answer
C. Torque.Explanation
When the propeller rotates clockwise, it creates a reaction force that causes the aircraft to rotate counter clockwise. This phenomenon is known as torque. Torque refers to the twisting force that occurs when a force is applied off-center or in a rotational motion. In this case, the torque is caused by the spinning propeller and results in the left turning tendency of the aircraft.Rate this question:

_____ is movement about the vertical or normal axis and is controlled by _____.
- A.
Yaw, rudder.
- B.
Roll, aileron.
- C.
Pitch, elevator.
- D.
Sideslip, elevator.
Correct Answer
A. Yaw, rudder.Explanation
Yaw is the movement about the vertical or normal axis, which is controlled by the rudder. The rudder is a control surface located on the vertical stabilizer of an aircraft, and it is used to control the yawing motion of the aircraft. By deflecting the rudder, the pilot can induce a yawing motion, causing the aircraft to turn left or right around its vertical axis. Therefore, the correct answer is Yaw, rudder.Rate this question:

The _____ is the angle that each wing makes with the horizontal. The purpose of this angle is to improve lateral stability.
- A.
Angle of incidence.
- B.
Dihedral angle.
- C.
Sweepback angle.
- D.
Dynamic angle.
Correct Answer
B. Dihedral angle.Explanation
The dihedral angle is the angle that each wing makes with the horizontal. This angle is designed to improve lateral stability. By angling the wings upwards, the dihedral angle creates a natural tendency for the aircraft to roll back to level flight if it starts to tilt to one side. This helps to prevent the aircraft from entering into an unstable or dangerous flight condition.Rate this question:

_____ is movement about the longitudinal axis and is controlled by _________.
- A.
Yaw, rudder.
- B.
Roll, aileron.
- C.
Pitch, elevator.
- D.
Sideslip, elevator.
Correct Answer
B. Roll, aileron.Explanation
Roll is the movement about the longitudinal axis of an aircraft, which is controlled by the aileron. The ailerons are hinged control surfaces on the trailing edge of the wings that move in opposite directions to create a difference in lift between the two wings, causing the aircraft to roll. This allows the aircraft to bank and turn.Rate this question:

The _____ is the angle at which the wing is permanently inclined to the longitudinal axis of the airplane.
- A.
Angle of incidence.
- B.
Dihedral angle.
- C.
Angle of attack.
- D.
Deviation.
Correct Answer
A. Angle of incidence.Explanation
The angle of incidence refers to the angle at which the wing is permanently inclined to the longitudinal axis of the airplane. This angle is fixed during the design and construction of the aircraft and determines the lift and stability characteristics of the wing. It is different from the angle of attack, which is the angle between the oncoming airflow and the wing's chord line, and can change during flight. Dihedral angle refers to the upward angle between the wings of an aircraft, while deviation does not relate to the inclination of the wing.Rate this question:

When flying from an area of high pressure to an area of low pressure, the altimeter will read _____ than what the aircraft is actually flying.
- A.
Higher.
- B.
Lower.
- C.
The same.
- D.
Towards the front.
Correct Answer
A. Higher.Explanation
When flying from an area of high pressure to an area of low pressure, the altimeter will read higher than what the aircraft is actually flying. This is because air pressure decreases with increasing altitude. In an area of high pressure, the altimeter will measure a higher pressure, indicating a lower altitude than the actual altitude. As the aircraft moves to an area of low pressure, the altimeter will measure a lower pressure, indicating a higher altitude than the actual altitude.Rate this question:

Buy Ballots law states that in the Northern Hemisphere with your back to the wind the center of the low is_____?
- A.
To your left.
- B.
To your right.
- C.
Towards the rear.
- D.
Towards the front.
Correct Answer
A. To your left.Explanation
According to Buys Ballot's law, in the Northern Hemisphere, when you stand with your back to the wind, the center of the low-pressure system will be to your left. This is because the wind circulates counterclockwise around a low-pressure system in the Northern Hemisphere. Therefore, the wind will be coming from your right side, indicating that the center of the low is to your left.Rate this question:

The closer the isobars are on a weather map, the _________;
- A.
Steeper the pressure gradient and weaker the winds.
- B.
Steeper the pressure gradient and the stronger the winds.
- C.
Shallower the pressure gradient and the weaker the winds.
- D.
Shallower the pressure gradient and the stronger the winds.
Correct Answer
B. Steeper the pressure gradient and the stronger the winds.Explanation
The closer the isobars are on a weather map, the steeper the pressure gradient. This means that there is a larger change in pressure over a shorter distance. A steep pressure gradient indicates a faster rate of change in pressure, which in turn leads to stronger winds. Therefore, when the isobars are closer together, the pressure gradient is steeper and the winds are stronger.Rate this question:
-

What direction do the winds blow around a low pressure?
- A.
Clockwise and outward.
- B.
Clockwise and inward.
- C.
Counterclockwise and outward.
- D.
Counterclockwise and inward.
Correct Answer
D. Counterclockwise and inward.Explanation
Low pressure systems are characterized by rising air, which creates a void that is filled by air from surrounding areas. As air moves from areas of higher pressure to areas of lower pressure, it is deflected due to the Coriolis effect. In the Northern Hemisphere, this deflection causes the air to rotate counterclockwise around the low pressure center, while in the Southern Hemisphere, it rotates clockwise. The inward direction refers to the air moving towards the center of the low pressure system. Therefore, counterclockwise and inward is the correct answer.Rate this question:

The angle between true meridian and magnetic meridian is called_____.
- A.
Compass heading.
- B.
Deviation.
- C.
Angle of Incidence.
- D.
Variation.
Correct Answer
D. Variation.Explanation
The angle between the true meridian and the magnetic meridian is called variation. Variation refers to the difference between the direction indicated by a magnetic compass and the true north. It is caused by the Earth's magnetic field and varies depending on the geographical location. Compass heading refers to the direction indicated by a compass. Deviation refers to the error introduced by the magnetic materials and electrical systems on a vessel that can affect the accuracy of a compass. Angle of incidence refers to the angle at which a ray of light or other radiation strikes a surface.Rate this question:

A nautical mile is _____.
- A.
Average length of one minute of latitude
- B.
Average length of one minute of longitude.
- C.
5280'
- D.
Both A and C.
Correct Answer
A. Average length of one minute of latitudeExplanation
A nautical mile is the average length of one minute of latitude. This means that for every minute of latitude traveled, the distance covered is equivalent to one nautical mile. The length of a nautical mile is not determined by longitude or any other unit of measurement, but specifically by the minute of latitude.Rate this question:

A compass heading is _______.
- A.
Magnetic heading minus west deviation.
- B.
Magnetic heading plus west deviation.
- C.
True heading minus west deviation.
- D.
True heading plus west deviation.
Correct Answer
B. Magnetic heading plus west deviation.Explanation
The correct answer is "Magnetic heading plus west deviation." A compass heading is the direction in which a compass needle points, and it is influenced by the Earth's magnetic field. The magnetic heading is the direction indicated by the compass, and the west deviation refers to the angular difference between the magnetic heading and the true heading. Adding the west deviation to the magnetic heading gives the correct compass heading.Rate this question:

On turns from north, northerly turning error causes the compass to ______;
- A.
Lead.
- B.
Indicate correctly.
- C.
Lag.
- D.
None of the above.
Correct Answer
C. Lag.Explanation
When turning from the north, northerly turning error causes the compass to lag. This means that the compass will initially indicate a turn in the opposite direction, causing a delay in accurately reflecting the correct heading. This error is caused by the magnetic properties of the Earth and the compass needle's tendency to align with the magnetic meridian rather than the true north. As a result, the compass lags behind the actual turn being made.Rate this question:

Given a track of 060 deg true, with a variation of 23 deg West and a deviation of 3 deg East, then the compass heading is ______;
- A.
40
- B.
86
- C.
34
- D.
80
Correct Answer
D. 80Explanation
The compass heading can be calculated by subtracting the deviation from the track and then adding the variation. In this case, the deviation is 3 degrees East, so we subtract 3 from the track of 060 degrees to get 057 degrees. Then we add the variation of 23 degrees West to get a compass heading of 080 degrees.Rate this question:

The volume in the cylinder above the piston when it is at the bottom of the compression stroke compared to the volume when it has moved up to the top of the stroke is known as the ______.
- A.
Power stroke.
- B.
Horse power.
- C.
Compression ratio.
- D.
Radial ratio.
Correct Answer
C. Compression ratio.Explanation
The volume in the cylinder above the piston when it is at the bottom of the compression stroke compared to the volume when it has moved up to the top of the stroke is known as the compression ratio. This ratio is important in determining the efficiency and performance of an engine, as it affects the amount of air-fuel mixture that can be compressed and ignited in the cylinder. A higher compression ratio generally leads to more power and efficiency in an engine. The power stroke is a different phase of the engine cycle, where the ignited air-fuel mixture expands and produces power. Horsepower and radial ratio are unrelated to the volume change in the cylinder.Rate this question:

Octane numbers go only as high as 100, Beyond this number the anti knock value of the fuel is expressed as a ___________.
- A.
Octane rating.
- B.
Viscosity level.
- C.
Performance number.
- D.
MOGAS indicator.
Correct Answer
C. Performance number.Explanation
Octane numbers are used to measure the anti-knock value of fuel, with higher numbers indicating better performance. However, octane numbers only go up to 100. When the anti-knock value exceeds 100, it is expressed as a performance number. Viscosity level, MOGAS indicator, and octane rating are not directly related to the anti-knock value of fuel.Rate this question:

The distance in feet a propeller travels forward in one revolution is called ______.
- A.
Pitch.
- B.
Roll.
- C.
Inclination.
- D.
Rate.
Correct Answer
A. Pitch.Explanation
The distance in feet a propeller travels forward in one revolution is called pitch. Pitch refers to the angle at which the propeller blades are set and determines how much air the propeller can move in one revolution. A higher pitch means the blades are set at a steeper angle, resulting in more forward movement per revolution. Conversely, a lower pitch means the blades are set at a shallower angle, resulting in less forward movement per revolution. Therefore, pitch accurately describes the distance a propeller travels forward in one revolution.Rate this question:

In air cooled engines ______ are added to the cylinders to provide a greater area of metal to dissipate the heat.
- A.
Fins.
- B.
Trim tabs.
- C.
Ribs.
- D.
Hot plates.
Correct Answer
A. Fins.Explanation
Fins are added to the cylinders in air cooled engines to provide a greater area of metal to dissipate the heat. Fins increase the surface area of the cylinders, allowing for more efficient heat transfer to the surrounding air. This helps to prevent overheating of the engine and ensures optimal performance. Trim tabs, ribs, and hot plates are not typically used for this purpose in air cooled engines.Rate this question:

If the exhaust valve were to close 20 degrees late on the exhaust stroke this would mean that both valves would be open at the same time. when this occurs the valves are said to be ______.
- A.
In sync.
- B.
Fitted.
- C.
Overlapped.
- D.
Congruent.
Correct Answer
C. Overlapped.Explanation
If the exhaust valve were to close 20 degrees late on the exhaust stroke, it would result in both the intake and exhaust valves being open at the same time. This condition is known as valve overlap, where the opening and closing of the intake and exhaust valves overlap in the engine cycle. This allows for better scavenging of exhaust gases and improved engine performance. Therefore, the correct term to describe this situation is "overlapped."Rate this question:
