Aqua planeing is just that.Planeing on the top of the water.It came into being whilst trying to stop aircraft after landing on 'wet'runways,with the tire not in contact with the surface!!!
The tire does not spinup the spoilers,or the reversers and the aircraft goes off the end..If the brakes are on the rubber boils with the friction and steam..
In the takeoff case the tire is in contact with the surface,the water night constitute a drag(more tham 3mm)but in this case skimming the top would help the takeoff case!!It's only when one wants to stop we're back to square one-Aquaplaneing,thats why the V1 is lower-to give you more room to stop.
