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, operations, snow and/or clearing:
“O Time and Change!—with hair as gray
As was my sire’s that winter day,
How strange it seems, with so much gone
Of life and love, to still live on!
Ah, brother! only I and thou
Are left of all that circle now,—
The dear home faces whereupon
That fitful firelight paled and shone.”
—John Greenleaf Whittier (1807–1892)
“We give lovely parties that last through the night,
I dress as a woman and scream with delight,
We wake up at lunch time and find we’re still tight.
What could be duller than that?”
—Noël Coward (1899–1973)
“You can’t have operations without screams. Pain and the knife—they’re inseparable.”
—Jean Scott Rogers. Robert Day. Mr. Blount (Frank Pettingell)
“When men were all asleep the snow came flying,
In large white flakes falling on the city brown,
Stealthily and perpetually settling and loosely lying,
Hushing the latest traffic of the drowsy town;”
—Robert Bridges (1844–1930)
“[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)
