Where can you find the CG of a 737?

• A. On the flight deck placard
• B. Always behind the wings
• C. Always found at the tail
• D. CG is always found between the wings. It must fall within a CG envelope.

Answer: (D)

The center of gravity is the airplane’s balance point, determined by summing all weights times their moments. It’s not a fixed mark on the aircraft; it moves with how the plane is loaded. To fly safely, the CG must stay within the published CG envelope, which defines forward and aft limits that ensure stable handling and enough elevator authority. On a 737, as with most airliners, that envelope places the usable CG roughly along the wing area, so the CG is effectively somewhere between the wings. That’s why the statement that the CG is always found between the wings and must fall within a CG envelope is the best description. The other choices aren’t correct because the CG isn’t a single placard location, it isn’t fixed behind the wings or always at the tail, and the key requirement is staying within the established CG envelope, not a fixed spot on the airframe.
