Final answer:
To be dispatched, the air operator must increase the runway requirements to account for landing on a wet runway.
Step-by-step explanation:
In order to be dispatched, the air operator must increase the calculated runway requirements for an additional distance on a wet runway. This additional distance accounts for the decrease in braking ability and tire traction on a wet surface.
The air operator would need to refer to wet runway performance charts provided by the aircraft manufacturer to determine the specific distance that needs to be added. These charts take into account factors such as aircraft weight, speed, and runway conditions.
The increase in calculated runway requirements ensures that the aircraft will have enough runway available to safely land and stop on a wet surface.
