Adding weight to the baggage compartment affects the longitudinal center of gravity by shifting it aft.

• A. Forward
• B. Aft
• C. Upward
• D. No change

Answer: (B)

The center of gravity is the balance point along the aircraft’s length. It’s the weighted average location of all the mass, so where you put additional weight directly moves that balance point. Adding weight to the baggage compartment, which sits behind the original CG, increases the rearward moment and pulls the balance point toward the tail. In other words, the CG shifts aft when you add mass behind the CG. The amount of shift depends on how heavy the baggage is and how far behind the original CG it sits, relative to the total weight of the airplane after the addition. If the baggage were placed forward, the CG would move forward instead. Keeping the CG within safe limits is essential for stable and controllable flight.
