Hydroplaning: What are the remedies?
 
Good evening,

I please wish to know what are the remedies after landing, on slush or a wet runway, resulting in hydroplaning.

Viscous, dynamic or even steam hydroplaning, how will i pilot respond to the phenomenon?

I am guessing the pilot should release the brakes :confused:
I please wish to know more details on countering hydroplaning.

Great day,
thanks in advance,

I would think that you do not release the brakes, as with modern a/c the anti-skid will release the brakes for you.:confused:

Speed and tire pressure.
 
The few times that I've actually experienced hydroplaning was during heavy rain with standing water on a poorly maintained runway--with either depressions or ruts where the water could collect before eventually running off.

In other words, you're not only protected by modern equipment but also modern runway design. It's just not that big of a factor in real world flying because the conditions have to be fairly degraded (runway condition) and the rainfall quite heavy.

That said, what else can a pilot do except slow down?

The two biggest variables are speed and tire pressure. You can't do anything about tire pressure so you better slow down. If you're confident in your anti-skid then more reverse thrust might be appropriate. Ensure that the spoilers are deployed.

If no anti-skid is installed (or deferred?) then I would be careful with braking as I would be on patchy ice. The possibility of locking up a tire is greater and then when you transition to bare pavement, naturally, you risk a flat spot or worse, a blown tire.

Every situation is different. Certainly pick the runway that points most into the wind!

Good luck.
:cool:
