An aircraft with a Centre of Gravity towards the aft limit will experience what change in range and stalling speed?

• A. An increased range and decreased stalling speed
• B. An increased range and increased stalling speed
• C. A decreased range and decreased stalling speed
• D. A decreased range and increased stalling speed

Answer: (A)

When an aircraft's center of gravity is positioned towards the aft limit, the effects on range and stalling speed can be understood through fundamental aerodynamic principles. Having a rearward center of gravity results in the aircraft being generally more stable during straight and level flight. This stability allows the aircraft to maintain a more efficient flight profile, potentially leading to an increased range. The aerodynamic forces acting on the aircraft are optimized, reducing drag during cruise flight. Thus, with efficient lift-to-drag ratios, the aircraft can fly further on the same amount of fuel. Additionally, a more aft center of gravity can lead to a decrease in stalling speed. This is because an aft center of gravity allows the aircraft to achieve a higher angle of attack before reaching the critical state at which it stalls. As a result, the aircraft can fly at lower speeds before transitioning into a stall condition. This does not mean that the aircraft becomes “safer” at all speeds; the characteristics are simply altered. Therefore, an aircraft with a center of gravity towards the aft limit experiences an increased range and a decreased stalling speed, reflecting the aerodynamic advantages provided by this specific weight distribution.
