Again it appears necessary for the industry to revisit the presentation on Managing Threats and Errors during Approach and Landing; the presenter notes give additional cautionary information; … it could happen to us.
Whilst searching for more information on aquaplaning I was surprised by a paper which “concluded that modern aircraft tires have lower hydroplaning speeds than those predicted by the well-known and commonly accepted equation 9xSQR tyre pressure”. This is taken from 2nd International Meeting on Aircraft Performance on Contaminated Runways pages 14 and 265-269; (beware 11mb pdf).
Hydroplaning could occur as low as 6xSQR tyre pressure, so for a 125psi tyre instead of being at risk of aquaplaning above 100 kts it could be as low as 67kts.The paper also noted that hydroplaning has occurred on grooved runways.
Other papers given at the meeting discussed the problems of directional control on contaminated surfaces.
