Occurs on any surface, generally at high speed. Water builds up in front of a rolling tire, which allows it to ride on a cushion of water, losing contact with the runway surface.
Dynamic Hydroplaning
Occurs at lower speeds, when a tire encounters a slippery surface from oils, grease, dirt and rubber combine with water or other liquid.
Viscous Hydroplaning
Caused by rubber heat build up under a tire due to friction. Mainly happens during landing.

Eliminates potential human error by automatically computing and recording friction averages for each one-third of the runway.
Electronic Decelerometer
Used as a backup. Requires longer runway down times and do not provide automatic friction averages.
Mechanical Decelerometer
Recommended for pavement surfaces covered with contaminants, as they provide a continuous graphic record of the pavement surface friction with averages for each one-third zone of the runway. May be self-contained or towed.

Friction Mat Sweepers
These are suspended beneath tugs and trucks to pick up metallic material. Should be cleaned regularly as to not cause FOD itself.
Magnetic Bars
