How does center of gravity affect multi-engine aircraft performance?

The center of gravity (CG) is a critical factor in the performance and handling characteristics of a multi-engine aircraft. When the CG is located within the designated limits, it ensures that the aircraft performs optimally in various flight conditions. However, if the CG is too far forward or too far aft, it can lead to significant performance issues.

In particular, the CG's position is crucial during scenarios such as engine failure. If one engine fails, the aircraft will generate asymmetric thrust, causing it to yaw toward the inoperative engine. The position of the CG will influence how much corrective input is required from the pilot to maintain balanced flight. A CG that is too far forward can increase the amount of right rudder needed when the left engine fails, potentially leading to a higher risk of loss of control. Conversely, if the CG is too far aft, the aircraft can become more difficult to control even with a functioning engine.

Furthermore, the CG affects the margin of stability and controllability. Multi-engine aircraft are designed with specific CG limits to optimize performance, ensuring that pilots can effectively manage the flight during critical maneuvers, such as go-arounds or single-engine operations. Correctly managing the CG not only contributes to safe and efficient flight but also plays
