In terms of the dry take off case,increased groundspeed during an abort causes a huge increase in stopping distance.Viscous hydroplaning can occur with very little water on the runway and a 10 knot tailwind would,in this case, bring the onset of hydroplaning down to an IAS around,typically, 55 knots.On a slippery runway this would make most a/c field length limited for t/o.There was a useful thread on hydroplaning a couple of weeks ago.
