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 16 bar. Use 1 bar = 14.5038 psi and round to the nearest knot.
Under the current Air OPS contaminated-runway definition and its AMC, a significant portion means more than 25% of one runway third within the usable length and width. Which listed runway-surface substances are contamination descriptors? 1 - ordinary visible dampness or a reflective water film no deeper than 3 mm; 2 - standing water deeper than 3 mm, or dry/wet snow or slush; 3 - compacted snow; 4 - ice, including wet ice; 5 - moist grass as the normal runway surface.
A very thin water film covers a smooth touchdown area coated with accumulated rubber. With no locked-wheel skid, which hydroplaning mechanism can occur?
The maximum validity of a SNOWTAM is:
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 10.8 bar. Use 1 bar = 14.5038 psi and round to the nearest knot.
Using the EASA training approximation for rotating-tyre dynamic hydroplaning spin-down speed, V (kt) = 9 × √p with p in psi, what is the estimate for 206 psi, rounded to the nearest knot?
Which statement correctly applies the current Air OPS contaminated-runway definition and AMC?
A NOTAM publishes new declared distances, with runway length available reduced below the published length because of reported conditions. Where is this reduced length, in metres, reported in a GRF SNOWTAM?
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 14 bar. Use 1 bar = 14.5038 psi and round to the nearest knot.
On a GRF Runway Condition Report, a Runway Condition Code (RWYCC) of 1 corresponds to a pilot-reported braking action of:
