CG stands for which term?

• A. Center of Gravity
• B. Center of Lift
• C. Center of Pressure
• D. Gravity Center

Answer: (A)

Center of Gravity is the point through which the aircraft’s total weight can be considered to act, essentially the balance point. Knowing the CG location is crucial because it directly affects stability and controllability: a forward CG increases stability but requires more aft elevator to pitch up, while an aft CG makes the airplane more maneuverable but reduces stability and can lead to less controllable flight in certain conditions. The other terms refer to different aerodynamic concepts—Center of Lift relates to where lift acts, and Center of Pressure is the aerodynamic pressure point on a surface—so they describe forces other than where the aircraft’s weight acts. Gravity Center isn’t the standard aviation term.
