The empty weight CG is defined as the center of gravity of the aircraft when it is in what condition?

• A. With full fuel
• B. In service with crew and cargo
• C. Empty (no usable load)
• D. When loaded to maximum payload

Answer: (C)

The concept being tested is how a aircraft’s center of gravity is defined for planning and stability. The empty weight CG is the balance point of the airplane in its empty condition, meaning no usable payload is on board and typically no usable fuel is considered for this reference. This gives a baseline distribution of weight from the fixed structure, engines, and installed systems. Once you add passengers, cargo, or fuel, weight is added at various locations and the CG shifts away from that baseline depending on where the loads are placed. So the scenario that describes the aircraft with no usable load matches the definition of the empty weight CG.
