Solution
The use of a small amount of flap during level flight at a low IAS (Indicated Airspeed) may be an advantage because the flaps will:
a. Reduce drag: This is incorrect. Flaps actually increase drag because they change the shape of the wing to increase lift. This change in shape also increases the amount of air resistance or drag.
b. Require a lower pitch attitude: This is incorrect. The use of flaps will actually require a higher pitch attitude to maintain level flight because of the increased drag.
c. Enable lift to exceed weight: This is correct. The main purpose of flaps is to increase lift. This increased lift can help the aircraft to maintain or even climb at a lower airspeed.
d. Require a lower power setting: This is incorrect. Because flaps increase drag, more power is actually required to maintain the same airspeed and altitude.
So, the correct answer is c. Enable lift to exceed weight.
