What is the center of gravity (CG) of an aircraft?

The center of gravity (CG) of an aircraft is defined as the point at which the aircraft's weight is evenly distributed around all axes. This concept is crucial in aviation because the CG affects the aircraft's stability, control, and performance. When the CG is appropriately located, the aircraft will behave predictably during flight, making it easier and safer to operate.

In this context, the CG is influenced by the distribution of weight in the aircraft, including passengers, cargo, fuel, and the structure itself. Proper weight and balance calculations ensure that the aircraft remains within safe operational limits, contributing to effective flight handling characteristics.

Understanding the CG helps pilots and maintenance personnel make informed decisions about loading the aircraft, which can significantly impact the performance and safety during flight.
