Plain English Meaning

The front-most and rear-most points where the airplane's balance point is allowed to be. As long as the airplane's balance point sits between these two points, it will handle the way the manufacturer designed it to.

Full Definition

The forward and aft boundaries within which the airplane's center of gravity must remain for safe flight. These limits are published by the manufacturer for each airplane and define the allowable range of loading. Operating outside CG limits compromises stability, controllability, and structural safety margins.

Context Anchor

Used during weight-and-balance planning before flight, especially when loading fuel, passengers, bags, or cargo.

Derivation

CG stands for center of gravity. “” points to the middle or balance point, and “” refers to pulling downward. “Limits” means the allowed boundaries, so CG limits are the allowed boundaries for the airplane’s balance point.
