Webhydroplaning is the most commonly encountered cause of low friction on wet runways, and occurrences are often mistaken for dynamic hydroplaning. Dynamic hydroplaning is the technical term for what is commonly called hydroplaning (see figure 1b). During total dynamic hydroplaning the tire lifts off the pavement and rides on a wedge of water like WebThis action is usually referred to as “dynamic hydroplaning.” Its occurrence is a function of water depth and aircraft speeds. The same phenomenon can result when a thin film of water on the runway mixes with the contaminants present or if the surface texture of the runway is smooth. This is called “viscous hydroplaning.” WebAug 7, 2024 · Dynamic hydroplaning occurs when the groundspeed is at least 8.73 times the square root of the tire pressure of the main tires.
