Airport Cleaning During Snowstorms: High-Speed Operation for Flight Safety A snowstorm for a modern airport is not a reason to stop operations, but a complex but routine engineering task solved with military precision and speed. The process of snow removal on the runway is a synchronized operation of special equipment, meteorological services, and controllers, where each element is subordinate to a single goal: maintaining the runway, taxiways, and aprons in a state as close to dry as possible. A delay of a few minutes here results in millions of dollars in losses and a chain reaction of failures in the global aviation network. Phase 1: Preparation – Work Before Snow The effectiveness of snow removal is determined by actions taken in advance. Monitoring and forecasting. The airport meteorological service works based on its own sensors installed around the field and data from national meteorological agencies. It is not only the expected precipitation that matters, but also the temperature of the runway surface, dew point, wind speed, and direction. The decision to start snow removal is made several hours before the snowstorm. Assembling the "snow caravan" (Snow Team/Fleet). This is a special column of equipment, the composition of which is strictly regulated. A typical caravan includes: Rotary Snowploughs: Powerful machines with a rotating auger and rotor capable of throwing wet and compacted snow up to 50 meters. This is "heavy artillery" for heavy snowfall. Plough Blowers: Machines combining an shovel for snow gathering and a fan for throwing it. Pavers/Tampers: Compacting loose snow to facilitate its subsequent cutting. Chemical reagent spreaders. Do not use ordinary salt, which causes corrosion of the aircraft skin. Special liquids based on potassium acetate or glycol, as well as solid granulated reagents (urea, potassium formate) are used. Their task is to prevent the formation of a "snow-surface" bond so that snow can be removed mechanically. Phase 2: Operation ... Read more
