Chapter 5, Aerodynamics of Flight

Question 1

The angle of Attack is the angle between the chord line of the wing and the ____________ wind.

Answer 1

Relative

Question 2

When airspeed decreases the angle of attack must be _____________ to maintain the same amount of lift.

Answer 2

Increased

Question 3

What is the inherent quality of an aircraft to correct for conditions that may disturb its equilibrium and to return to the original flight path?

Answer 3

Stability

Question 4

What results from a rapid decrease in lift caused by the separation of airflow from the wing’s surface brought on by exceeding the critical AOA?

Answer 4

Stall

Question 5

True or false, in a stall, the wing stops producing lift.

Answer 5

False

Question 6

What are most aircraft normally designed to do when their wings stall?

Answer 6

Pitch nose down

Question 7

How does ice and frost accumulation on a wing affect the angle of attack at which the wing will stall?

Answer 7

The wing will stall at a lower angle of attack

Question 8

What causes an aircraft’s weight to increase while decreasing its ability to create lift?

Answer 8

Ice accumulation

Question 9

An AOA indicator gives the pilot an indication of the difference between the angle of attack at which the aircraft will stall and what.

Answer 9

The current angle of attack

Question 10

For a given configuration, an aircraft will always stall at the same ____________.

Answer 10

Angle of attack
