Exceeding prescribed weight and balance limits during flight planning can lead to which outcomes?

• A. No effect on performance.
• B. Degraded performance, stability, and controllability.
• C. Improved maneuverability.
• D. Increases fuel efficiency.

Answer: (B)

Keeping weight and balance within the approved envelope ensures the airplane behaves predictably in flight. When you exceed those limits, the aircraft’s performance and how it responds to pilot inputs can suffer because the weight distribution changes the wing’s load and the effectiveness of control surfaces. Heavier weight raises stall speed and can lengthen takeoff and landing distances, reduces climb rate, and increases fuel burn. If the center of gravity is outside its safe range, stability and controllability are affected: a forward CG can make the airplane stiff to rotate and pitch up, while an aft CG can make it overly sensitive and harder to recover from stalls or gusts. All of these effects mean degraded performance, stability, and controllability, which is why staying within the prescribed limits is essential. The other options don’t fit because excess weight or an out-of-range balance does not improve maneuverability or fuel efficiency, nor does it leave performance unchanged.
