Question 1

Which of the following describes Bernoulli's principle in relation to aerodynamic lift?

For every action, there is an equal and opposite reaction. As the speed of a moving fluid increases, the pressure within that fluid increases. Lift is directly proportional to the aircraft's weight. As the speed of a moving fluid increases, the pressure within that fluid decreases.

Correct Answer:

As the speed of a moving fluid increases, the pressure within that fluid decreases.

Question 2

What is the angle of attack (AOA) of a wing defined as?

The angle between the wing's leading edge and the horizontal horizon. The angle between the longitudinal axis of the fuselage and the chord line. The angle between the wing's chord line and the direction of the relative airflow. The angle between the wing's chord line and the horizontal plane.

Correct Answer:

The angle between the wing's chord line and the direction of the relative airflow.

Question 3

In steady, unaccelerated level flight, what are the relationships between the four primary forces?

Lift is greater than Weight, and Thrust is greater than Drag. Lift is equal to Drag, and Thrust is equal to Weight. Lift equals Thrust, and Weight equals Drag. Lift equals Weight, and Thrust equals Drag.

Correct Answer:

Lift equals Weight, and Thrust equals Drag.

Question 4

How do induced drag and parasite drag change as an aircraft's airspeed increases?

Induced drag increases, while parasite drag decreases. Both induced drag and parasite drag increase. Induced drag decreases, while parasite drag increases. Both induced drag and parasite drag decrease.

Correct Answer:

Induced drag decreases, while parasite drag increases.

Question 5

What is the primary purpose of incorporating washout (wing twist) into a wing's design?

To reduce parasite drag at high cruise speeds. To increase the total lift produced by the wingtips. To allow the aircraft to climb at a steeper angle. To ensure the wing root stalls before the wingtip, maintaining aileron control during a stall.

Correct Answer:

To ensure the wing root stalls before the wingtip, maintaining aileron control during a stall.
