Excessive weight on an unmanned aircraft results in which of the following performance changes?

• A. Increased cruising speed
• B. Reduced maneuverability
• C. Longer range
• D. Higher ceiling

Answer: (B)

Excess weight increases wing loading and inertia, making the aircraft harder to change direction quickly. When a drone carries more mass, it takes more lift to stay level, which raises stall speed and reduces responsiveness. The control inputs produce slower roll, pitch, and yaw changes, so maneuverability—the ability to execute tight turns or rapid directional changes—diminishes. The other options don’t reflect the most direct effect: extra weight won’t reliably increase cruising speed, and it generally reduces both range and ceiling because more power is needed to maintain flight and climb. So, the performance change you’d notice with excessive weight is reduced maneuverability.
