How does maneuvering speed change with weight?

How does maneuvering speed change with weight?

• A. It is determined at maximum gross weight; as weight decreases, maneuvering speed increases.
• B. It is determined at lightest weight and increases with weight.
• C. As the aircraft gets lighter, the maneuvering speed gets slower.
• D. It decreases as weight increases only when at altitude.

Answer: (C)

The main idea here is that maneuvering speed (Va) changes with weight. Va is the speed at which full, abrupt control inputs could be made without overstressing the airframe, and it depends on how much the airplane weighs. Heavier airplanes can tolerate higher load factors before reaching structural limits, so Va is higher at greater weights. When the airplane becomes lighter, its wing loading is reduced and the safe margin decreases, so Va becomes lower. That’s why the correct statement is that as the aircraft gets lighter, the maneuvering speed gets slower. The other options imply Va is fixed at a heavy weight or increases with lightness, or only changes with altitude, which doesn’t match how Va actually behaves with weight.
