When are negative camber airfoils used?

Question

Quizplus · Accepted Answer

Therefore, the correct answer to the question "When are negative camber airfoils used?" is:
A) To support inverted flight
Negative camber airfoils are not typically designed to maximize lift in normal (upright) flight conditions (B), to maximize speed (C), or to minimize drag (E) in the same way that other airfoil shapes might be. They are also not specifically used in heavier aircraft (D); the use of negative camber is more about the aerobatic capability of the aircraft rather than its weight.
