CG range is the distance between forward and aft CG limits. Which option best expresses this definition?

• A. The distance between the forward and aft CG limits indicated on specifications.
• B. The distance from nose to CG.
• C. The distance from CG to wing tip.
• D. The distance between wing tips.

Answer: (A)

CG range is the distance between the forward and aft center of gravity limits as set by the aircraft’s specifications. This range defines the span of allowable CG positions you must stay within to ensure stable and controllable flight. The option that says the distance between the forward and aft CG limits indicated on specifications is the best expression because it directly matches how weight and balance data are published and used in practice. Other distances described—nose to CG, CG to wing tip, or wing tips to wing tips—do not represent the allowable CG span; they refer to locations or other aircraft dimensions, not the safe range for the center of gravity.
