Three Variations of Hydroplaning, with Strategies to Counteract Them
Flying Safely on Wet Runways: Navigating the Dangers of Hydroplaning
Slip-up on the runway can be a pilot's worst nightmare, but fear not! Here's how to avoid three common hydroplaning scenarios and land like a pro, even in the pouring rain.
1) Dynamic Hydroplaning
You might think water play is fun, but not when it lifts your wheels off the runway. Essentially, you'll be riding on water, losing traction and braking power. This mishap, known as dynamic hydroplaning, typically occurs at around 56 knots for a Cessna 172 with 42 PSI tires[1]. Here's how to stay grounded:
- Don't touch down fast.
- Maintain proper tire inflation.
- Use back pressure and aerodynamic braking to control your speed.
2) Reverted Rubber Hydroplaning
This situation happens when your tires lock up, causing them to melt and creating a steam pocket beneath them. Essentially, you're melting your tires while riding on steam! Here's how to prevent it:
- Use light brake pressure.
- Maintain maximum weight on your landing gear.
- Avoid locking brakes during landing.
3) Viscous Hydroplaning
Oil or deposited rubber mixed with water can form a slippery layer that your tires can't penetrate, especially on smooth asphalt runways. Here's how to fly safe:
- Land on a grooved runway, if possible.
- Don't touch down fast.
- Maintain proper tire inflation.
- Use back pressure and aerodynamic braking to slow down, and light brake pressure.
