← ScienceWhich outcome occurs when an aircraft's center of gravity shifts significantly aft of the design limits?
A)Increased stall speed and stability
B)Reduced longitudinal stability and control✓
C)Improved fuel efficiency and range
D)Decreased takeoff distance and climb rate
💡 Explanation
When the center of gravity shifts aft, the static stability margin decreases because the restoring moment arm reduces, making the aircraft more sensitive to pitch changes. Therefore reduced longitudinal stability results, rather than increased stability, improved efficiency, or improved takeoff performance, which require a forward CG or other aerodynamic changes.
