How often must a runway that is cold milled be swept?

• A. Once a week
• B. Daily and immediately after milling
• C. Every two days
• D. Only when it rains

Answer: (B)

A runway that has been cold milled must be swept daily and immediately after the milling process to ensure safety and functionality. Cold milling generates a significant amount of debris, including aggregates and fine materials, which can create hazards for aircraft during takeoff and landing. Regular sweeping helps maintain a clear and safe runway surface by removing this debris, thereby preventing potential damage to aircraft engines and ensuring optimal traction for landing and takeoff. Immediate sweeping following the milling also prevents the initial material from settling back onto the runway, which can create uneven surfaces or potential obstacles for pilots. Implementing this procedure as part of runway maintenance practices is crucial for flight safety and operational efficiency.
