Practise Operational Procedures
Using the EASA training approximation for rotating-tyre dynamic hydroplaning spin-down speed, V (kt) = 9 × √p, with p in psi, estimate V for a tyre pressure of 12 bar. Use 1 bar = 14.5038 psi and round to the nearest knot.
Under the current Air OPS definition, a wet runway has visible dampness or water up to and including 3 mm deep within the area intended for use. Which listed conditions fall within that definition? 1 - water no deeper than 3 mm; 2 - visible dampness that changes the surface colour without a shiny appearance; 3 - a reflective moisture film no deeper than 3 mm; 4 - standing water deeper than 3 mm.
Using the EASA training approximation for rotating-tyre dynamic hydroplaning spin-down speed, V (kt) = 9 × √p, with p in psi, estimate V for a tyre pressure of 10 bar. Use 1 bar = 14.5038 psi and round to the nearest knot.
Under the current Air OPS definition, a runway with visible dampness but no shiny appearance is classified as:
Using the EASA training approximation for rotating-tyre dynamic hydroplaning spin-down speed, V (kt) = 9 × √p with p in psi, estimate V for 8 bar. Use 1 bar = 14.5038 psi and round to the nearest knot.
For a performance class A CAT aeroplane at dispatch, weather information indicates a wet runway at ETA. No applicable AFM wet-runway landing-distance data, special friction-improving data or reduced-landing-distance approval is available. Under CAT.POL.A.235(a)(2), by what percentage is the required dry-runway landing distance determined under CAT.POL.A.230 increased?
