Contaminated Runway
Definition
A runway with more than 25% of its surface covered by water, snow, slush, or ice. Contaminated runway performance data accounts for reduced braking action and increased stopping distances.
Why Contaminated Runway Matters for Pilots
Performance planning directly affects flight safety. Knowing how Contaminated Runway works helps you calculate whether a takeoff or landing is safe for given conditions. FAA and EASA exams frequently test performance concepts, and examiners expect you to apply Contaminated Runway to real-world scenarios during oral exams and checkrides.
Exam Tip
This concept is commonly tested in performance-related questions on FAA and EASA exams. Make sure you can explain Contaminated Runway in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
