Dry runway意思

"Dry runway" is an aviation term that refers to a runway that is not wet or slippery due to rain, water, ice, snow, or any other type of precipitation or surface condition that could affect the traction or braking performance of an aircraft. In other words, it means that the runway surface is dry and safe for landing and taking off.

This term is used in contrast to a "wet runway," which is a runway that has standing water or is otherwise wet due to precipitation, or a "contaminated runway," which is a runway that has any type of foreign substance on it that could affect an aircraft's performance, such as snow, slush, ice, or oil.

When pilots and air traffic controllers refer to a dry runway, they are indicating that there are no special conditions that require special landing or takeoff procedures due to the runway's surface conditions. However, it's important to note that a "dry runway" can still have other factors that affect landing performance, such as strong winds, crosswinds, or high temperatures.
