What is the significance of the aircraft’s center of gravity (CG) in flight operations?

• A. It influences fuel capacity
• B. It affects stability, control, and performance
• C. It determines the flight route
• D. It governs engine performance

Answer: (B)

The aircraft's center of gravity (CG) plays a pivotal role in flight operations primarily because it directly influences stability, control, and performance. The CG is the point where the aircraft's mass is concentrated, and its location relative to the aircraft's design and center of lift is crucial for safe and effective maneuvering.

When the CG is within the specified limits, the aircraft exhibits stable flight characteristics, allowing for predictable handling during various phases of flight. For instance, if the CG is too far forward or too far aft, it can lead to undesirable flight characteristics such as excessive nose-up or nose-down attitudes, which can complicate control and increase pilot workload.

Furthermore, the position of the CG affects the aircraft's performance. A well-positioned CG enhances lift and reduces drag, which can lead to improved fuel efficiency and optimized flight profiles. Therefore, maintaining the correct CG is essential for ensuring safe operations, effective maneuverability, and overall performance of the aircraft.
