How is TOLD affected by a wet runway?

The impact of a wet runway on TOLD (Takeoff and Landing Distance) is significant, and one of the most notable effects is the increase in landing distance. When a runway is wet, the aircraft experiences reduced braking effectiveness due to hydroplaning and lower friction between the tires and the runway surface. This decreased friction means that the aircraft will take longer to stop after landing, thereby increasing the landing distance required.

In addition to the longer distance needed to land, the reduced friction affects the overall safety margins on wet runways. Pilots must account for this variability in performance, especially if weather conditions can change during a flight.

The other options, while they touch on important aspects of aircraft performance, do not accurately reflect the primary consequence of a wet runway on landing distances. Thus, the increase in landing distance is the most critical point to acknowledge regarding TOLD in such conditions.
