What effect does overloading an unmanned aircraft typically have on its flight performance?

Overloading an unmanned aircraft typically leads to a shortened range. When an aircraft is loaded beyond its specified weight limits, it experiences several negative impacts on its flight performance. This excess weight increases the power required for the aircraft to achieve and maintain flight, resulting in higher fuel or battery consumption during operation. Consequently, the aircraft may not be able to travel as far as it could under optimal loading conditions.

This reduction in range can affect mission planning and operational effectiveness, as the aircraft may be unable to reach its intended destination or return safely. Other excessive loads can also lead to reduced stability and control, making it harder to maneuver the aircraft effectively, thus further compromising its performance and safety.

The other options suggest improvements in performance traits that would not occur with an overloaded aircraft, making them less applicable in this context.
