For an aeroplane with a tyre pressure of 10 bars, there is a risk of dynamic hydroplaning as soon as the…

  • A
    Speed is greater than 96 kt.
  • B
    Water depth is equal to the half of the depth of the tyre grooves.
  • C
    Speed is greater than 108 kt.
  • D
    Runway temperature is greater than 40°C.
Dynamic Hydroplaning Speed formula: V = 34 √ P
Where V stands for velocity (kt) and P is tyre pressure (bars)
  • V = 34 √ 10 = approx. 108 kt
