The thing is none of this stuff is hard, CASA make it hard. The difficulty of the ATPL exams have no correlation to air safety, but try telling CASA that.
For each type of hydroplaning, pilots may need to adjust their actions and techniques to mitigate the risks and maintain control of the aircraft:
- Dynamic hydroplaning:
- To minimize the risk of dynamic hydroplaning, pilots should ensure that their aircraft is equipped with effective anti-skid systems, which can help prevent the tires from losing traction.
- Pilots should also be prepared to reduce their approach speed and increase their following distance during wet conditions to allow for increased stopping distance.
- Reverted rubber hydroplaning:
- Pilots should be aware of runway surface conditions, especially if rubber deposits are present, such as on heavily trafficked or older runways.
- To reduce the risk of reverted rubber hydroplaning, pilots can apply gentle braking pressure to keep the tires from skidding and maintain better traction.
- Viscous hydroplaning:
- Pilots should be vigilant for standing water on the runway surface, especially during heavy rain or poor drainage conditions.
- To mitigate the risk of viscous hydroplaning, pilots should consider using higher tire pressures, which can help reduce the likelihood of tire sinking into the water film.
- Steam hydroplaning:
- Pilots should be particularly cautious when landing or taking off from runways with standing water and high surface temperatures.
- To minimize the risk of steam hydroplaning, pilots can consider reducing their approach or takeoff speeds, providing additional margin for error in case of loss of traction.
- Pilots should also be prepared to apply firm, but smooth, braking and steering inputs to regain control if hydroplaning occurs.
