WebbDealing with the Problem of Taking Off from Slush- or Water-covered Runways to address the take-off situation. An updated version (1968) was used as the basis for guidance material for the European Joint Aviation Authorities JAR 25, now CS-25. WebbThe presence of runway contamination such as standing or running water, snow, slush or ice on the runway has a particularly serious effect on landing performance and if it cannot be cleared, it must be reported as accurately as possible using runway condition codes (RWYCC) as given by the Global Reporting Format.

Webb18 sep. 2024 · The wet and contaminated runways affect aircraft handling mainly on landing. When pilots apply braking after touchdown, a frictional force is developed. This frictional force mainly depends on two factors. One on the load on the aircraft (its weight) and the coefficient of friction (depends on surface conditions).
