If an aircraft's empty weight moment is reported as 102.04 in-lb/1,000, how does that relate to the operational CG?

• A. It indicates a stable CG.
• B. It could imply a need for weight change.
• C. It confirms compliance with weight regulations.
• D. It has no effect on CG.

Answer: (B)

The reported empty weight moment of 102.04 in-lb/1,000 is a measure that provides information about the distribution of weight within the aircraft, which directly impacts the center of gravity (CG). The empty weight moment is a critical factor in assessing the balance of an aircraft, as it helps determine where the CG is located in relation to the aircraft's design parameters. When the moment is specified, it can indicate whether the CG is located within acceptable limits for safe flight operations. A moment that suggests the CG is outside of desired operational limits may imply a need for adjustments, such as redistributing weight or adding/removing weight, to ensure the aircraft is properly balanced. Proper CG positioning is essential for stability and controllability during flight. While the other options can relate to CG concerns, they do not directly address the implications of the weight moment. For example, stability depends on various factors including design and load configuration, while compliance with weight regulations typically concerns maximum gross weight and not specifically the CG as indicated by the moment. The notion that it has no effect on CG is inaccurate, as the moment is foundational to determining CG location and thus impacts aircraft performance and safety.
