What is the consequence of exceeding the aft CG limit during flight operations?

• A. Increased turn performance
• B. Reduced aircraft stability
• C. Improved climb rates
• D. Enhanced control authority

Answer: (B)

Exceeding the aft center of gravity (CG) limit during flight operations has the principal consequence of reducing aircraft stability. When the CG is too far aft, the aircraft's balance shifts, and it becomes less stable in pitch. This can lead to a situation where the aircraft is more prone to uncommanded nose-up or nose-down attitudes, making it difficult for pilots to control the aircraft effectively. Stability is crucial for safe flight, as it ensures that the aircraft returns to its original attitude after being disturbed.

In contrast, options like increased turn performance or improved climb rates are typically associated with an aircraft having a forward CG, while enhanced control authority would not be a result of an aft CG position, as a well-balanced aircraft is necessary for maintaining positive control. Therefore, understanding the implications of CG limits is essential for safe aircraft operation, as it directly affects flight characteristics and pilot control.
