What could happen if the center of gravity is outside of the specified limits during aircraft assembly?

When the center of gravity (CG) is located outside of the specified limits during aircraft assembly, it can lead to significant stability and control issues. The CG of an aircraft is a critical factor that influences how the aircraft responds to control inputs and behaves in various flight conditions.

If the CG is too far forward or too far aft, the aircraft may exhibit undesirable flight characteristics. For instance, a forward CG can lead to increased need for elevator control, making the aircraft more difficult to maneuver and possibly leading to a stall. Conversely, an aft CG can result in reduced stability, making the aircraft prone to uncontrollable pitch oscillations, which can result in a loss of control.

These potential issues illustrate how important it is to maintain the CG within the specified limits to ensure the aircraft operates safely and efficiently. In contrast, a properly balanced aircraft enhances performance across various phases of flight, including takeoff, maneuverability, and stability during landing.
