More Information
A runway is considered contaminated when more than 25% of its surface is covered by certain conditions like snow, water, or ice, which can significantly affect aircraft performance.
Tips
A common mistake is assuming a damp runway is contaminated; it only applies when there is significant standing water, slush, or snow.
