What is the typical result of exceeding the aircraft's weight limit?

Exceeding the aircraft's weight limit typically results in reduced stability and control. When an aircraft is overweight, its performance characteristics are adversely affected. This includes longer takeoff distances, reduced climb rates, and potential difficulty in maneuvering. The aircraft's center of gravity may also shift, further compromising stability. This instability can make it harder to maintain control, especially during critical phases of flight such as takeoff and landing.

In contrast, improved climb performance, increased fuel efficiency, and no significant effects on performance do not accurately reflect the consequences of operating an aircraft beyond its weight limits. Overloading an aircraft defeats its ability to operate as designed, leading to safety concerns. Thus, recognizing the importance of weight limits is crucial for safe flight operations.
