Lift, Angle of Attack, Stalls

Question 1

Bernoulli’s Principle is:

Answer 1

that air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface

Question 2

Angle of Attack defined:

Answer 2

it is the angle between the wing chord line and the relative wind

Question 3

The angle of attack at which an airplane wing stalls, remains the same regardless of:

Answer 3

gross weight

Question 4

As the altitude increases the indicated airspeed at which a given airplane stalls in a particular configuration will:

Answer 4

remain the same regardless of altitude

Question 5

In order to spin, an airplane must be:

Answer 5

stalled

Question 6

During a spin to the LEFT, which wings are stalled?

Answer 6

Both

Question 7

The term “Angle of Attack” is defined as:

Answer 7

the angle between the Chord Line of the Wing and the Relative Wind.
