If the wing stalls, what is the most important action to recover?

• Apply back pressure.

• Reduce the angle of attack to less than its critical value.

• Let go of the controls.

If order for an airplane to spin, it must be stalled first.

• True

• False

When are the four forces that act on an airplane in equilibrium?

Stall recovery is harder for an aircraft with an aft center of gravity (CG).

• True

• False

Which lift principle relates to the statement 'As the airspeed increases the pressure decreases'?

• Newton

• Bernoulli

When is a stall most likely to occur?

• Any pitch or speed

• Near the ground

• During night flight

• During colder months

The chord line is an imaginary line connecting which of the following?

• Wing root with wing tip

• Leading edge to the trailing edge of the wing

• Wing tip to wing tip

If the wing stalls, what is the most important action to recover?

• Apply back pressure.

• Reduce the angle of attack to less than its critical value.

• Let go of the controls.

Induced drag is drag caused by the same factors that produce

• lift

• airspeed

• thrust
