If you distribute weight toward the mid-arms, what happens to CG position?

• A. Move CG toward the tail
• B. Move CG toward the forward limit
• C. Move CG toward the middle of the aircraft, near the center CG
• D. Move CG does not change

Answer: (C)

Distributing weight toward the mid-arms shifts the balance point toward the aircraft’s center. The center of gravity is the weighted average location of all loads, so placing more weight near the center pulls that average toward the center of the aircraft. In practice, moving weight away from the forward or aft extremes toward the middle reduces the moments those extreme weights contribute, causing the CG to move inward, toward the middle near the aircraft’s center of gravity. It won’t move toward the tail or toward the forward limit unless weight is actually moved in those directions, and it will change as soon as weight is redistributed.
