Snow removal is somewhat of an art form if you really want to do it right, and even more challenging for an airport where salt cannot be used!!
There’s more science and math behind airfield snow removal than you might realize.
When severe winter weather hits MKG, it might look like we’re just plowing,
but behind every pass of a plow, broom, blower, or deice truck is a lot of math, physics, FAA regulations and science.
Here’s how it works:
🔹 Plowing comes first to remove the bulk accumulation. We have to keep pavement friction high enough for aircraft to safely land and take off and every eighth-inch of snow affects braking distance - significantly!
🔹 Sweeping immediately follows. This isn’t simply “dusting off” the runway, especially with MKG’s prevalent wet snow. Sweeping removes the thin bonded layer of snow in the top asphalt course that a plow can’t get. If that layer is left behind, it can quickly turn into ice and close a runway. Minutes matter here.
🔹 Chemical application (like potassium acetate) is timed with precision. Too early and it dilutes or gets buried in snow. Too late and ice bonds to the pavement. The goal is to prevent ice from forming in the first place (called anti-icing) break it apart if it has already formed (called de-icing). Remember, we can’t use traditional salt on the airfield.
🔹 Temperature matters. Pavement temps, significantly affect when chemicals work best. Believe it or not, runway pavement can be 5–15 degrees warmer or colder than the air around it. The sun helps a lot, which we don’t see much of.
🔹 Wind & humidity matter too. They change how fast snow sticks, melts, or re-freezes, which affects how fast we have to respond and how often we need to make another pass. Wind often creates “finger drifts” that we always have to control.
So if you ever see our crews out there making the same lap for the 20th time in a storm… that’s because keeping runways safe isn’t a one-and-done job. It’s a full-on science experiment in real time, 24-hours a day, 7-days a week, all winter long. Todays complex wet weather right at freezing temps was tough.
