What is the primary consequence of increased camber on an aircraft wing?

Increasing the camber of an aircraft wing enhances the curvature of the wing's upper surface relative to its lower surface. This change in shape alters the airflow characteristics around the wing, leading to a higher pressure difference between the upper and lower surfaces during flight.

As the camber increases, the airflow accelerates over the curved upper surface, resulting in a decrease in pressure above the wing. This increased lift generation occurs at a given angle of attack, allowing the aircraft to produce more lift without requiring a corresponding increase in the angle of attack or airspeed. Enhanced camber is particularly beneficial at lower airspeeds and during takeoff and landing, as it allows the aircraft to maintain effective lift at these critical phases of flight.

While the other choices may touch upon relevant aspects of aerodynamics, they do not accurately capture the primary outcome of increased camber. For instance, reducing effective wing area is not a direct consequence of increased camber, nor does it inherently lead to decreased stability or simple increases in drag without considering lift. The increase in lift is the most significant and intended result of increasing camber on a wing.
