In aviation, the term CG stands for Center of Gravity. The center of gravity is a crucial concept in aircraft design and operation, representing the point where the weight of the aircraft is evenly distributed in all directions. It plays a vital role in the stability and control of an aircraft. When the CG is correctly positioned within certain limits, the aircraft will handle predictably and efficiently in flight.

If the CG is too far forward or aft, it can lead to changes in performance, such as increased drag, difficulty in controlling the aircraft, and potential stalling issues. Proper loading and weight distribution are essential for ensuring that the CG remains within safe limits before and during flight. Understanding the CG is vital for pilots in order to perform accurate weight and balance calculations, which directly affect flight safety and performance.
