A definition of the term 'viscous hydroplaning' is where. the airplane rides on standing water. a film of moisture covers the painted or rubber-coated portion of the runway. The tires of the airplane are actually riding on a mixture of steam and melted rubber.

Compared to dynamic hydroplaning, at what speed does viscous hydroplaning occur when landing on a smooth, wet runway?. At approximately 2.0 times the speed that dynamic hydroplaning occurs. At a lower speed than dynamic hydroplaning. At the same speed as dynamic hydroplaning.

Which term describes the hydroplaning which occurs when an airplane's tire is effectively held off a smooth runway surface by steam generated by friction?. Reverted rubber hydroplaning. Dynamic hydroplaning. Viscous hydroplaning.

What is the best method of speed reduction if hydroplaning is experienced on landing?. Apply full main wheel braking only. Apply nosewheel and main wheel braking alternately and abruptly. Apply aerodynamic braking to the fullest advantage.
