A condition that can exist when a high-speed aircraft lands on a water-covered runway. Water forms a fine film between tires and the runway surface, thus rendering braking relatively ineffective. It can cause aircraft to skid. An effective antiskid system can prevent hydroplaning. Runway grooving is the most effective method of preventing hydroplaning. The rule of thumb for determining the minimum hydroplaning speed in knots is to multiply the square root of the tire pressure in psi by 8.6. The degree of hydroplaning depends on the amount of tire surface that is under water. See aquaplaning.

The speed when the tire is completely separated from the road is called the critical hydroplaning speed.
CAUSES: Going too fast around a corner, hydroplaning over standing water, driving over ice or braking too hard.
The biggest danger during a landing on contaminated runways is hydroplaning (see sidebar above), but pilots continue to stack the deck to their disadvantage.
The hydroplaning may or may not have been avoided; however, had we asked for the runway conditions on the approach, we could have determined whether to take a short-field arrestment.
Hydroplaning cars, flooded basements, and sometimes--as in the case of Europe last summer--staggering economic losses.
The aggressive "peak & valley" profile provides traction and prevents hydroplaning even when wet.
The most serious type of skidding, hydroplaning, develops when speed is high (generally above 50 mph, although this can vary) and the running surface so wet that the wheels ride above the surface on a film of water or even steam if the frictional heat of a skidding tire has vaporized the film.
Give yourself plenty of time to brake and do so gently in order to avoid hydroplaning.
The tire is engineered with Pulse Groove Technology that improves water evacuation and increases resistance to hydroplaning.
It is well known that hydroplaning (or aquaplaning) is the movement of an object on the surface of water when the object remains on the surface only due to the velocity head of water, i.
The cause of the accident was hydroplaning u the result of a failure to reduce the speed of the vehicle, he said.
Since footprint pressure is closely related to hydroplaning resistance, lower aspect ratio tire hydroplaning resistance is not as high as that of high aspect ratio tires.
