Wet runway ops

[p0ngkid]

Hi guys,

I have a question regarding the take-off on a wet runway. I know the ASDA will be longer due to a lower friction on the runway. That is because the energy is applied on the wheels and they could skid over the runway.

But how does a wet runway affect the start of the take-off? Since the energy is not applied on the wheels but on the plane itself, the lower frictioncoefficient should have no influence on the wheels. Still it seems that the aircraft needs more runway for the first part (before V1)

I would say that the runway friction coefficient should only affect the braking (ASDA) part, can anyone clarify?

thanks!
