Which of the following best describes the role of the Center of Gravity in UAS design?

The role of the Center of Gravity (CG) in UAS design is crucial for stabilizing flight. The center of gravity is the point at which the weight of the UAS is evenly distributed in all directions. When the CG is correctly positioned, it ensures that the aircraft remains balanced during flight, which is essential for maintaining stability. A well-positioned CG helps the UAS to respond appropriately to control inputs and environmental factors, such as wind, thereby enhancing the overall flight performance and safety.

For instance, if the CG is too far forward or too far back, the UAS may become difficult to control, leading to potentially hazardous situations. Thus, understanding and achieving the correct CG is fundamental in the design and operation of UAS, as it directly affects not just stability but also maneuverability and overall flight efficiency.
