What issue arises from overbanking tendencies during flight?

Overbanking tendencies during flight can lead to difficulties in handling the aircraft because the aircraft may enter a bank angle that exceeds the optimal range for stable flight. This results in increased load factors and can make it more challenging for the pilot to maintain control. When an aircraft is overbanked, it may require significant corrections to return to a level flight attitude, which can be disorienting, particularly in situations where quick responses are necessary. Pilots must constantly monitor and adjust their bank angles to ensure safe flight, and overbanking can disrupt this delicate balance, leading to further complications such as loss of altitude or increased risk of stalling.

In contrast, the other options describe outcomes that are generally not associated with overbanking. For example, overbanking does not typically enhance maneuverability, decrease the risk of stalling, or reduce aerodynamic drag; instead, it can overload the aircraft's wings and lead to challenging dynamics during flight.
