For a lot of components of the Northern Hemisphere, the 2022/2023 winter was gentle in comparison with earlier years. Regardless of this, airport managers know they need to put together effectively prematurely for winter seasons as you by no means know what mom nature can throw at you.
Very similar to maintaining the roads open in order that car visitors can get from level A to level B, airports have plans in place to take care of snow and ice. Because of specialist gear and chemical compounds, airports can hold their runways away from such contamination in order that plane can safely take off and land.
Airports assessment their previous winter efficiency and start planning for the subsequent
Typically talking, as quickly as the prospect of receiving extra snow and ice lessens, airports will assess how they carried out and begin planning for the next winter. Airports have to be prepared for winter climate and work with suppliers and contractors to make sure they’ve all of the gear and chemical compounds to do the job.
Additionally they want to arrange staffing ranges to make sure they’ve sufficient staff for when the dangerous climate hits. Moreover having sufficient workers for the job, airports should educate new personnel, so that they know what they are going to be required to do. This entails coaching which often begins in October in preparation for early winter snow storms.

As Finland lies on the identical northern latitude as Nunavut, Canada, Helsinki Airport (HEL) is aware of a factor or two about snow elimination. Finnish airport operator Finavia can clear an 11,500 ft lengthy, 180 ft broad runway of snow in 13 minutes.
To perform this, they use highly effective Vammas PSB 5500 sweeper blowers, specifically constructed to be used at End airports. The monster snow plows can take away any snow from the runway, and potent 1,500 hp snowblowers shoot the snow within the air, the place it lands 164 ft away.
Smaller snow-removing gear just like the snow plows you see on highways are additionally used to take away snow, and loaders then fill dump vans with snow to move it to an space far-off from the runway. This prevents it from blowing again on the runway by the wind.
Chemical compounds are used to soften ice
As soon as the runway is evident of snow, particular rigged vans with 82-foot booms unfold chemical compounds on the runway to soften ice. Essentially the most generally used merchandise for this objective are:
- Sodium Formate
- Ethylene/Propylene Glycol-based fluids
- Urea
- Potassium Acetate (KAc)
- Sodium Acetate
- Potassium Formate (KF)
Regardless of all of the heavy specialist gear, customary four-wheel drive SUVs are one of the crucial essential airport autos. Winter upkeep crews use them to measure the friction on the runway’s floor and to entry all components of the airport.

New climate expertise helps airports plan
As new expertise is developed, airport floor crews at all times think about making snow-clearing operations extra environment friendly. Probably the most important aids is superior climate forecasting. By utilizing GPS monitoring and reside radar feeds, airport managers can have all of the employees and gear prepared and in place for when the storm strikes.
Not all airports are as effectively equipped for snow elimination as Helsinki, and there are occasions when lots of them can’t cope and have to shut. Nonetheless, with correct planning, groups, and gear, most snow-prone airports are able to take care of winter circumstances.
