Hydroplaning speed
I was recently asked by a mate about Vp, the hydroplaning speed.
Yes, most of us know Horne's equation Vp = 9 x square root tire press (psi) = ... kts.
Let's say the tire pressure is 220 psi, so Vp is about 135 kts or less (tire tread).
How does it influence take off calcs?
How is it implied in modern performance data tools (wet/contaminated runway)?
Thx
