How pilots stop airplanes from hydroplaning on wet runways?

Answer 1

All answers are correct, there is one additional important function of the spoilers.

Just as much as they increase drag, they push the aircraft downward.

You can apply brakes all you want but when a flight is touching down, its basically gliding and touching above the runway.

When spoilers are set, it puts a downward pressure on the airplane and thus the brakes become effective and thus slows the airplane PLUS prevents the airplane from hydroplaning PLUS pilots on a heavy rainy day slams the airplane to the runway so that the tires dont hydroplane.

Thats why you typically see a rough landing on a rainy day but smooth landing otherwise.
