Commercial Pilot Airplane (CAX) Performance Practice Exam

In weight and balance terminology, 'CG' stands for "Center of gravity." The center of gravity is a crucial concept in aviation as it represents the point where the aircraft's weight is evenly distributed in all directions. Properly understanding the CG is essential for maintaining stability and control during flight. An improperly calculated CG can lead to performance issues; for instance, if the CG is too far forward or too far aft, it can affect the aircraft's handling characteristics, leading to potential safety hazards.

The other terms, while they may have relevance in different contexts, do not pertain to weight and balance in the same fundamental way that the center of gravity does. The emphasis on CG is particularly vital during pre-flight planning and loading procedures to ensure that the aircraft remains within its operational envelope.
