What does "aft CG" indicate regarding an aircraft's center of gravity?

An "aft CG" indicates that the center of gravity of the aircraft is positioned towards the rear. The location of the center of gravity is critical in determining the aircraft's stability and performance. When the CG is located aft, it can have several implications on how the aircraft handles in flight.

An aft CG can lead to a reduction in stability because the aircraft may become more sensitive to control inputs. While it can enhance certain performance aspects, like allowing for easier pitch control and potentially increasing lift, it can also result in a higher stall speed and a tendency to pitch up too easily. Pilots need to be particularly aware of how the location of the CG impacts the handling characteristics of the aircraft, especially during takeoff, cruising, and landing phases.
