GM1 CAT.POL.A.435(a)(1) Landing — wet and contaminated runways

CAA ORS9 Decision No. 15

AFM LANDING DISTANCES FOR WET RUNWAYS

Specific landing distances provided in the AFM for dispatch on wet runways, include a safety factor, which renders the application of the 15 % safety factor used in CAT.POL.A.435(a)(2) unnecessary, unless otherwise indicated. The operator should confirm whether or not such data includes a safety factor.

When the AFM distance is not factored, a safety factor of 15 % should be applied. The resulting distances may be longer or shorter than those resulting from CAT.POL.A.435(a)(2), but when factored distances are provided, they are intended as a replacement for CAT.POL.A.435(a)(2) and are mandatory for use at the time of dispatch.
