Winter Time Operations and Snow Clearing
Since its opening Stockholm Arlanda has always managed to continue its operations during heavy snowfall and difficult weather. The airport administration claims to be world-leading at clearing snow from the runways. Arlanda has a policy to never close due to snowfall. Heavy snowfall can however cause delays. During heavy snowfall at least one runway stays open but in bad weather condition there may be delays even if flight operations continue at all times. Not just runways need to be cleared, aprons and aircraft parking areas need snow clearing as well. The airport has a total of 250 000 m2 to clear from snow and ice, at the same time as the aircraft continue taking off and landing. During the colder half of the year Stockholm Arlanda has about 65 seasonally hired snow removal staff. Together with permanent staff, they form a team of 100 people who provide snow removal services. Special routes are planned for sweeping teams, which clear each route at intervals of 35 to 45 minutes. The sweeping teams are directed via radio from the air traffic control tower. When snow removal is completed on each runway the surface is tested by a friction vehicle which measures friction value. The airport announces the friction value, and then it is each pilot who decides whether this value is sufficient for a landing. The friction value determines how often a runway must be ploughed and treated with anti-skid agent.

Famous quotes containing the words winter time, winter, time, operations, snow and/or clearing:
“When I was a bachelor, I lived by myself
And I worked at the weaver’s trade;
The only, only, thing that I ever did wrong
Was to woo a fair young maid.
I wooed her in the winter time,
And in the summer too;
And the only, only thing that I ever did wrong
Was to keep her from the foggy, foggy dew.”
—Unknown. The Foggy, Foggy Dew (l. 1–8)
“People often become scholars for the same reason they become soldiers: simply because they are unfit for any other station. Their right hand has to earn them a livelihood; one might say they lie down like bears in winter and seek sustenance from their paws.”
—G.C. (Georg Christoph)
“It is a time when one’s spirit is subdued and sad, one knows not why; when the past seems a storm-swept desolation, life a vanity and a burden, and the future but a way to death.”

“Plot, rules, nor even poetry, are not half so great beauties in tragedy or comedy as a just imitation of nature, of character, of the passions and their operations in diversified situations.”
—Horace Walpole (1717–1797)
“Old age is
a flight of small
cheeping birds
skimming
bare trees
above a snow glaze.”
—William Carlos Williams (1883–1963)
“Though the words Canada East on the map stretch over many rivers and lakes and unexplored wildernesses, the actual Canada, which might be the colored portion of the map, is but a little clearing on the banks of the river, which one of those syllables would more than cover.”
—Henry David Thoreau (1817–1862)
