What types of runways are considered to have friction improving characteristics for the purpose of AMC1 CAT.POL.A.335(a)(3)?

Runways with friction improving characteristics include grooved runways, runways treated with PFC (porous friction course), or other materials or techniques for which the AFM provides specific performance data.

Which AMC section addresses landing on wet and contaminated runways and specifically mentions runways with friction improving characteristics?

AMC1 CAT.POL.A.335(a)(3) Landing -- wet and contaminated runways addresses this, and its section on runways with friction improving characteristics is the relevant part.

AMC1 CAT.POL.A.335(a)(3) Landing -- wet and contaminated runways

Q: Before taking AFM performance credit for a runway with improved friction characteristics, what must the operator verify?

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.

Q: Can an operator use AFM performance credit for a grooved runway if the runway is not maintained to preserve its friction properties?

No, the operator should verify that the runway is maintained to the extent necessary to ensure the expected improved friction characteristics before taking the AFM performance credit.

ED Decision 2021/005/R

RUNWAYS WITH FRICTION IMPROVING CHARACTERISTICS

(a) Materials or construction techniques meant to improve the friction characteristics of a runway may be grooved runways, runways treated with PFC or other materials or techniques for which the AFM provides specific performance data.

(b) 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.
