A pilot banks an airplane by using the
- A.
Brakes
- B.
Elevator
- C.
Ailerons
Correct Answer
C. AileronsExplanation
A pilot banks an airplane by using the ailerons. Ailerons are control surfaces located on the wings of an aircraft that move in opposite directions to create a rolling motion. By manipulating the ailerons, the pilot can increase the lift on one wing and decrease it on the other, causing the aircraft to tilt and bank in the desired direction. The brakes are used to slow down or stop the aircraft on the ground, while the elevator controls the pitch or up-and-down movement of the aircraft.Rate this question:

What part of the airplane controls the vertical axis?
- A.
Pilot
- B.
Rudder
- C.
Wing flaps
Correct Answer
B. RudderExplanation
The rudder is the correct answer because it is the part of the airplane that controls the vertical axis. It is located on the vertical stabilizer at the tail of the aircraft and is used by the pilot to control the yawing motion of the plane. By deflecting the rudder, the pilot can change the direction of the aircraft around its vertical axis, allowing for better control and stability during flight.Rate this question:

What is the backward or retarding force produced by air resistance termed?
- A.
Weight
- B.
Gravity
- C.
Drag
Correct Answer
C. DragExplanation
Drag is the term used to describe the backward or retarding force produced by air resistance. When an object moves through the air, the air molecules exert a resistance force on the object, slowing it down. This force is called drag. Drag depends on factors such as the shape, size, and speed of the object, as well as the density of the air. It is an important consideration in various fields, including aerodynamics and vehicle design, as it affects the performance and efficiency of objects moving through the air.Rate this question:

The angle between the chord line of the airfoil and the direction of the relative wind is termed:
- A.
Angle of attack
- B.
Angle of deflection
- C.
Triangle
Correct Answer
A. Angle of attackExplanation
The angle between the chord line of the airfoil and the direction of the relative wind is termed the angle of attack. This angle is important in determining the lift and drag forces acting on the airfoil. A higher angle of attack increases the lift but also increases the drag, while a lower angle of attack decreases both lift and drag. Therefore, the angle of attack is a crucial parameter in aerodynamics and aircraft performance.Rate this question:

In a steady flight condition,
- A.
Lift = weight; thrust = drag
- B.
Lift = gravity ; weight = drag
- C.
Drag = lift; weight = thrust
Correct Answer
A. Lift = weight; thrust = dragExplanation
In a steady flight condition, the forces acting on the aircraft must be balanced for it to maintain a constant altitude and speed. The lift force generated by the wings must be equal to the weight of the aircraft to counteract gravity and keep it in the air. Similarly, the thrust force generated by the engines must be equal to the drag force experienced by the aircraft due to air resistance. This balance ensures that the aircraft remains in a steady flight condition without any changes in altitude or speed.Rate this question:

If a hard surfaced runway is numbered 22, then the opposite runway is:
- A.
4
- B.
12
- C.
40
Correct Answer
C. 40Explanation
The opposite runway to a runway numbered 22 would be numbered 04. Runways are numbered based on their magnetic heading, rounded to the nearest 10 degrees. The opposite runway is always 180 degrees opposite in direction, so the 22 runway would be heading roughly northwest, and its opposite would be heading roughly southeast, which would be represented by the number 04.Rate this question:

- A.
North-South Direction
- B.
NNE-SSW Direction
- C.
East-West Direction
Correct Answer
A. North-South DirectionExplanation

Arms crossing over head signals a pilot to make the airplane:
- A.
Stop
- B.
Go
- C.
Taxi
Correct Answer
A. StopExplanation
When a pilot crosses their arms over their head, it is a signal for them to stop the airplane. This gesture is commonly used in aviation to communicate with ground personnel or other pilots. It indicates that the pilot wants to halt the movement of the aircraft and bring it to a complete stop. This could be due to various reasons such as a safety concern, a need for further instructions, or to avoid a potential collision.Rate this question:

Which of the following is an important performance deficiency of an over-loaded airplane?
- A.
Higher Landing Speed
- B.
Increased rate and angle of climb
- C.
Shorter take off runway
Correct Answer
A. Higher Landing SpeedExplanation
An important performance deficiency of an overloaded airplane is a higher landing speed. When an aircraft is carrying excessive weight, it requires a longer distance to slow down and land safely. This increased landing speed can put additional stress on the aircraft's landing gear and brakes, potentially leading to increased wear and tear, decreased braking effectiveness, and a higher risk of accidents during landing. Therefore, a higher landing speed is a significant performance deficiency that can compromise the safety and efficiency of an overloaded airplane.Rate this question:

During take off, a headwind will:
- A.
Shorten the takeoff run and decrease the angle of climb
- B.
Shorten the takeoff run and increase the angle of climb
- C.
Increase the takeoff run and decrease the angle of climb.
Correct Answer
B. Shorten the takeoff run and increase the angle of climbExplanation
During takeoff, a headwind refers to the wind blowing directly opposite to the aircraft's direction of travel. This headwind creates additional airspeed over the wings, resulting in increased lift. As a result, the aircraft requires a shorter distance to reach the necessary speed for takeoff, thus shortening the takeoff run. Additionally, the increased lift generated by the headwind allows the aircraft to achieve a steeper climb angle, increasing the angle of climb. Therefore, a headwind both shortens the takeoff run and increases the angle of climb.Rate this question:

The pilot always advances the throttle during:
- A.
Climb
- B.
Nose dive
- C.
Spin
Correct Answer
A. ClimbExplanation
During climb, the pilot always advances the throttle to increase the engine power and maintain a steady climb rate. By increasing the throttle, the pilot can increase the thrust produced by the engine, which helps the aircraft gain altitude and overcome the gravitational forces. Advancing the throttle allows the pilot to maintain a safe and controlled climb, ensuring that the aircraft reaches the desired altitude efficiently.Rate this question:

What makes an airplane turn?
- A.
Horizontal component of lift
- B.
Rudder and aileron
- C.
Vertical component of lift
Correct Answer
A. Horizontal component of liftExplanation
An airplane turns due to the horizontal component of lift. Lift is the force that opposes the weight of the airplane and keeps it in the air. When the airplane is banking into a turn, the wings generate lift at an angle. This angled lift creates a horizontal component that acts perpendicular to the direction of the turn. This horizontal component of lift helps to change the airplane's direction and allows it to turn. The rudder and ailerons also play a role in controlling the turn, but the primary factor is the horizontal component of lift.Rate this question:

The pilot of an airplane can best detect the approach of a stall by the:
- A.
Decrease in pitch
- B.
Ineffectiveness of the ailerons and elevator
- C.
Increase in the effectiveness of the rudder
Correct Answer
B. Ineffectiveness of the ailerons and elevatorExplanation
The best way for a pilot to detect the approach of a stall is by observing the ineffectiveness of the ailerons and elevator. When an airplane is nearing a stall, the airflow over the wings becomes disrupted, resulting in a loss of lift. As a result, the control surfaces like the ailerons (used for banking) and elevator (used for pitch control) become less responsive and less effective. This lack of response from the control surfaces serves as a clear indication to the pilot that the airplane is approaching a stall and immediate action needs to be taken to prevent it.Rate this question:
