Which equipment is commonly used for snow removal on runways?

Snow plows and snow blowers are specifically designed to efficiently remove snow from runways and other critical airport surfaces. Snow plows are used to push and clear accumulations of snow, effectively creating safe pathways for aircraft to take off and land. On the other hand, snow blowers provide the capability to not only remove snow but also to propel it away from the surface, preventing it from piling up again. This is especially useful in heavy snowfall scenarios where merely pushing the snow aside may not suffice, as it can quickly lead to dangerous conditions if not managed properly.

The other choices do not specialize in snow removal on runways. Tractors and salt spreaders might be helpful for applying materials to de-ice surfaces, but they do not primarily remove snow. Forklifts and conveyor belts are not designed for snow removal at all; they serve different functions in material handling. Airbags and de-icers are related to aircraft safety operations but do not directly address the immediate need for snow clearance on runways. Thus, snow plows and snow blowers are the most appropriate and effective tools for this critical task.
