A diagram of an aquaplaning tire Two vehicles aquaplaning through large puddles on the road's surface. Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs.
The poor water clearance of bar grips may limit their performance on very wet mud. With later patterns, such as the NATO, water may be squeezed out from between the blocks, leaving the mud drier and firmer. As the bar grip gives no escape for this water, they may retain a layer of water-lubricated mud like quicksand that remains extremely slippery.
The contributing factors for viscous hydroplaning are a damp or wet pavement, medium to high speed, poor pavement texture, and worn tire tread. If a runway has good microtexture and grooving and the aircraft tires have a good tread design, viscous hydroplaning could be alleviated.(NTSB, p.92) Macrotexture is visible to the naked eye.

Aircraft tires generally operate at high pressures, up to 200 psi (14 bar; 1,400 kPa) for airliners, [2] and even higher for business jets [citation needed].The main landing gear on the Concorde was typically inflated to 232 psi (16.0 bar), whilst its tail bumper gear tires were as high as 294 psi (20.3 bar).

A week ago, Dora Steed got separated from her husband and their boat while diving for scallops in the Gulf of Mexico, and she was forced to tread water for almost 13 hours before she was rescued.
Skye has made a new substance – called Clomp – in her lab at the Lunar Academy. It starts off soft, but hardens quite quickly – perfect for making moulds and sculptures. When a gear breaks on the base's water pump, a perfect replacement needs to be found quickly! Jim and Ripple have ordered a surprise for Eco – a "Choo Choo" plant.
A light plane with three people aboard landed safely without landing gear Monday after circling an Australian airport for almost three hours to burn off fuel. The pilot, Peter Schott, and his ...
