What is the primary function of snow melters in airport snow management?

The primary function of snow melters in airport snow management is to melt snow delivered by carrier trucks. Snow melters are specifically designed for this purpose, allowing airports to efficiently manage large quantities of snow accumulation. Instead of hauling snow away or using other methods that can be time-consuming or less efficient, snow melters provide a way to handle excess snow by converting it into water, which can then be safely drained away. This process not only helps keep the airport operational during winter weather but also reduces the need for additional manpower and equipment for snow removal.

The other options, while related to snow and ice management, do not directly pertain to the primary role of snow melters. Hauling snow away involves transporting snow off-site, which is a separate process that may be necessary in certain circumstances but is not the main function of snow melters. Removing ice from runways typically requires different equipment and methods, such as plows or chemical treatments. Similarly, spreading de-icing chemicals is a method utilized to enhance safety on runways and taxiways but is distinct from the melting of snow, which is what snow melters specifically address.
