AMC1 CAT.POL.A.235(a)(3) Landing — wet and contaminated runways
CAA ORS9 Decision No. 15
RUNWAYS WITH FRICTION IMPROVING CHARACTERISTICS
Materials or construction techniques meant to improve the friction characteristics of a runway may be grooved runways, runways treated with porous friction course (PFC) or other materials or techniques for which the AFM provides specific performance data.
Before taking the AFM performance credit for such runways, the operator should verify that the runways intended to be operated on are maintained to the extent necessary to ensure the expected improved friction characteristics.
