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)
“Thus Winter falls,
A heavy gloom oppressive o’er the world
Through Nature shedding influence malign,
And rouses up the seeds of dark disease.
The soul of man dies in him, loathing life,
And black with more than melancholy views.”
—James Thomson (1700–1748)
“Nor envy’s snaky eye, finds harbour here,
Nor flatterers’ venomous insinuations,
Nor cunning humorists’ puddled opinions,
Nor courteous ruin of proffered usury,
Nor time prattled away, cradle of ignorance,
Nor causeless duty, nor comber of arrogance,
Nor trifling title of vanity dazzleth us,
Nor golden manacles stand for a paradise;”
—Sir Philip Sidney (1554–1586)
“A sociosphere of contact, control, persuasion and dissuasion, of exhibitions of inhibitions in massive or homeopathic doses...: this is obscenity. All structures turned inside out and exhibited, all operations rendered visible. In America this goes all the way from the bewildering network of aerial telephone and electric wires ... to the concrete multiplication of all the bodily functions in the home, the litany of ingredients on the tiniest can of food, the exhibition of income or IQ.”
—Jean Baudrillard (b. 1929)
“There is a mountain in the distant West
That, sun-defying, in its deep ravines
Displays a cross of snow upon its side.
Such is the cross I wear upon my breast
These eighteen years, through all the changing scenes
And seasons, changeless since the day she died.”
—Henry Wadsworth Longfellow (1809–1882)
“[Panurge] spent everything in a thousand little banquets and joyous feasts open to all comers, particularly jolly companions, young lasses, and delightful wenches, and in clearing his lands, burning the big logs to sell the ashes, taking money in advance, buying dear, selling cheap, and eating his wheat in the blade.”
—François Rabelais (1494–1553)
