With an aft center of gravity, how does stall speed change compared to normal configurations?

• A. Stall speed is higher
• B. Stall speed is lower
• C. Stall speed remains constant
• D. Stall behavior becomes more predictable

Answer: (B)

With an aft center of gravity, stall speed decreases compared to normal configurations. This phenomenon occurs because the aircraft's center of gravity location influences its overall balance and aerodynamic efficiency. When the center of gravity is positioned further aft, the aircraft is more susceptible to entering a stall at lower airspeeds. In this configuration, the wing must produce less lift to maintain level flight at lower speeds. As the aircraft approaches the stall angle of attack, the ailerons become less effective, resulting in more unpredictable handling characteristics. Consequently, the aircraft may stall at a lower speed than what would be experienced with a more forward center of gravity. This highlights the importance of weight and balance considerations in flight operations, as an aft center of gravity not only lowers the stall speed but also can lead to a more difficult recovery from a stall.
