This means for a typical jet with a tyre pressure of around 200psi and a landing speed of around 130 knots the pilots should, after a firm landing to break through the surface water to ensure tyre contact and wheel spin up, use lift dump and thrust reversers as soon as possible and then, when below the hydroplaning onset speed of around 100 knots, apply one firm brake application and let the aircraft’s brake antiskid system do its job.
I guess we shouldn’t be using autobrakes on wet runways, then.
