During hydroplaning, which statement accurately describes the effect on aircraft handling and how anti-skid systems interact?

• A. Anti-skid systems have no effect on hydroplaning.
• B. Hydroplaning improves braking action.
• C. Hydroplaning occurs only on dry pavement.
• D. An effective anti-skid system can minimize the effects of hydroplaning.

Answer: (D)

Hydroplaning happens when a layer of water between the tire and runway greatly reduces friction, so braking effectiveness and directional control are diminished. An anti-skid system helps by preventing wheel lock and modulating brake pressure so the wheel stays rolling and can maintain the maximum possible friction with the surface. This keeps braking forces within the available traction and helps steer and control the airplane even on a wet runway. While it can’t restore dry-pavement friction, a well-functioning anti-skid system minimizes the loss of braking performance associated with hydroplaning, making it the best option.
