Between weight and balance, which factor is not directly affected by improper balance?

• A. Stability.
• B. Controllability.
• C. Climb performance.
• D. In-flight weather radar performance.

Answer: (D)

When you think about weight and balance, the key idea is how the center of gravity position changes how the airplane behaves in flight. The CG directly influences stability and controllability: a CG too far forward makes the aircraft very stable but sluggish to maneuver; a CG too far aft reduces stability and can make control more responsive but riskier in terms of control difficulty and stall characteristics. It also affects climb performance because the distribution of weight relative to thrust and lift changes the aircraft’s ability to climb efficiently. In-flight weather radar performance, however, comes from the radar system itself—the antenna alignment, power, and line of sight—not from where the airplane sits on the balance. So improper balance doesn’t directly alter radar function. That’s why this factor is the one not directly affected by balance.
