When do runway snow and ice control operations start?

• A. Prior to onset of snowfall or icing conditions
• B. During the snowfall
• C. After icing conditions
• D. Only after the runway is closed

Answer: (A)

Proactive pretreatment of the runway before precipitation begins is the best practice in runway snow and ice control. The goal is to apply anti-icing agents ahead of snowfall or icing so a protective film forms on the pavement, reducing ice and snow bonding and preserving pavement friction. This proactive approach allows quicker, more effective snow removal and safer operations when aircraft start to use the runway. Waiting until snowfall is underway or icing has started means the agents have less time to work, ice bonding is already forming, and removal becomes harder and slower, increasing risk and the chance of closures. In practice, snow and ice control activities are initiated before adverse weather reaches the runway, not only after it’s closed. So, the start of runway snow and ice control operations is before the onset of snowfall or icing conditions.
