What is a possible consequence of exceeding the aircraft's weight limitation?

Exceeding an aircraft's weight limitation can lead to increased landing distance, which is a critical safety concern. When an aircraft is heavier than its maximum weight capacity, it requires more runway length to come to a complete stop during landing. This is due to the principles of physics, specifically the extended kinetic energy that needs to be dissipated as the aircraft descends and lands.

A heavier aircraft has more momentum, which means that upon touchdown, it will take longer for the brakes to slow it down adequately. This is exacerbated if the runway conditions are not optimal, such as being wet or contaminated, which can further extend the landing distance required.

In contrast, the other options suggest improvements in performance or operational capabilities, which do not accurately reflect the vehicle limitations tied to weight restrictions. Exceeding weight limits generally leads to adverse effects, such as those related to safety, performance, and efficiency, rather than enhancements.
